Component firstLine

A relative positioning constant, that can be used instead of north, south, east, west or center. mixing the two types of constants can lead to unpredicable results. If you use both types, the relative constants will take precedence. For example, if you add components using both the NORTH and BEFORE_FIRST_LINE constants in a container whose orientation is LEFT_TO_RIGHT, only the BEFORE_FIRST_LINE will be layed out. This will be the same for lastLine, firstItem, lastItem.

 

Component lastLine

A relative positioning constant, that can be used instead of north, south, east, west or center. Please read Description for firstLine.

 

Component firstItem

A relative positioning constant, that can be used instead of north, south, east, west or center. Please read Description for firstLine.

See Also:

Component.dispatchEvent(java.awt.AWTEvent)

long eventMask

The eventMask is ONLY set by subclasses via enableEvents. The mask should NOT be set when listeners are registered so that we can distinguish the difference between when listeners request events and subclasses request them. One bit is used to indicate whether input methods are enabled; this bit is set by enableInputMethods and is on by default.

int gridx

Specifies the cell containing the leading edge of the component's display area, where the first cell in a row has gridx=0. The leading edge of a component's display area is its left edge for a horizontal, left-to-right container and its right edge for a horizontal, right-to-left container. The value RELATIVE specifies that the component be placed immediately following the component that was added to the container just before this component was added.

The default value is RELATIVE. gridx should be a non-negative value.

 

See Also:

GridBagConstraints.clone(), GridBagConstraints.gridy, ComponentOrientation

int gridy

Specifies the cell at the top of the component's display area, where the topmost cell has gridy=0. The value RELATIVE specifies that the component be placed just below the component that was added to the container just before this component was added.

double weightx

Specifies how to distribute extra horizontal space.

The grid bag layout manager calculates the weight of a column to be the maximum weightx of all the components in a column. If the resulting layout is smaller horizontally than the area it needs to fill, the extra space is distributed to each column in proportion to its weight. A column that has a weight of zero receives no extra space.

If all the weights are zero, all the extra space appears between the grids of the cell and the left and right edges.

The default value of this field is 0. weightx should be a non-negative value.

 

See Also:

GridBagConstraints.clone(), GridBagConstraints.weighty

double weighty

Specifies how to distribute extra vertical space.

The grid bag layout manager calculates the weight of a row to be the maximum weighty of all the components in a row. If the resulting layout is smaller vertically than the area it needs to fill, the extra space is distributed to each row in proportion to its weight. A row that has a weight of zero receives no extra space.

If all the weights are zero, all the extra space appears between the grids of the cell and the top and bottom edges.

The default value of this field is 0. weighty should be a non-negative value.

 

See Also:

GridBagConstraints.clone(), GridBagConstraints.weightx

int anchor

This field is used when the component is smaller than its display area. It determines where, within the display area, to place the component.

The absolute values are: CENTER, NORTH, NORTHEAST, EAST, SOUTHEAST, SOUTH, SOUTHWEST, WEST, and NORTHWEST. The relative values are: PAGE_START, PAGE_END, LINE_START, LINE_END, FIRST_LINE_START, FIRST_LINE_END, LAST_LINE_START and LAST_LINE_END. The default value is CENTER.

 

See Also:

GridBagConstraints.clone(), ComponentOrientation

int fill

This field is used when the component's display area is larger than the component's requested size. It determines whether to resize the component, and if so, how.

The following values are valid for fill:

• NONE: Do not resize the component.
• HORIZONTAL: Make the component wide enough to fill its display area horizontally, but do not change its height.
• VERTICAL: Make the component tall enough to fill its display area vertically, but do not change its width.
• BOTH: Make the component fill its display area entirely.

The default value is NONE.

Reads default serializable fields from the stream. Reads from the stream a string and an array of bytes as additional data.

Serial Data:

The String is the name of one of CS_* constants defined in the ColorSpace class if the profile object is a profile for a predefined color space (for example "CS_sRGB"). The string is null otherwise.

The byte[] array is the profile data for the profile. It will usually be null for the predefined profiles.

If the string is recognized as a constant name for predefined color space the object will be resolved into profile obtained with getInstance(int cspace) and the profile data are ignored. Otherwise the object will be resolved into profile obtained with getInstance(byte[] data).

Throws:

IOException - thrown by ObjectInputStream.

ClassNotFoundException - thrown by ObjectInputStream.

Serial Data:

The String is the name of one of CS_* constants defined in the ColorSpace class if the profile object is a profile for a predefined color space (for example "CS_sRGB"). The string is null otherwise.

The byte[] array is the profile data for the profile. For predefined color spaces null is written instead of the profile data. If in the future versions of Java API new predefined color spaces will be added, future versions of this class may choose to write for new predefined color spaces not only the color space name, but the profile data as well so that older versions could still deserialize the object.

readObject for custom serialization.

This method reads this object's serialized form for this class as follows:

The readObject method is invoked on in to read this object's unique identifier (a UID instance).

Next, the readUTF method is invoked on in to read the external ref type name of the RemoteRef instance for this object's activator. Next, the RemoteRef instance is created of an implementation-specific class corresponding to the external ref type name (returned by readUTF), and the readExternal method is invoked on that RemoteRef instance to read the external form corresponding to the external ref type name.

Note: If the external ref type name is "UnicastRef", "UnicastServerRef", "UnicastRef2", "UnicastServerRef2", or "ActivatableRef", a corresponding implementation-specific class must be found, and its readExternal method must read the serial data for that external ref type name as specified to be written in the serialData documentation for this class. If the external ref type name is any other string (of non-zero length), a ClassNotFoundException will be thrown, unless the implementation provides an implementation-specific class corresponding to that external ref type name, in which case the RemoteRef will be an instance of that implementation-specific class.

Throws:

IOException

writeObject for custom serialization.

This method writes this object's serialized form for this class as follows:

The writeObject method is invoked on out passing this object's unique identifier (a UID instance) as the argument.

Next, the getRefClass method is invoked on the activator's RemoteRef instance to obtain its external ref type name. Next, the writeUTF method is invoked on out with the value returned by getRefClass, and then the writeExternal method is invoked on the RemoteRef instance passing out as the argument.

Serial Data:

The serialized data for this class comprises a java.rmi.server.UID (written with ObjectOutput.writeObject) followed by the external ref type name of the activator's RemoteRef instance (a string written with ObjectOutput.writeUTF), followed by the external form of the RemoteRef instance as written by its writeExternal method.

The external ref type name of the RemoteRef instance is determined using the definitions of external ref type names specified in the RemoteObject writeObject method serialData specification. Similarly, the data written by the writeExternal method and read by the readExternal method of RemoteRef implementation classes corresponding to each of the defined external ref type names is specified in the RemoteObject writeObject method serialData specification.

                        ClassNotFoundException

readObject for custom serialization.

This method reads this object's serialized form for this class as follows:

The readUTF method is invoked on in to read the external ref type name for the RemoteRef instance to be filled in to this object's ref field. If the string returned by readUTF has length zero, the readObject method is invoked on in, and than the value returned by readObject is cast to RemoteRef and this object's ref field is set to that value. Otherwise, this object's ref field is set to a RemoteRef instance that is created of an implementation-specific class corresponding to the external ref type name returned by readUTF, and then the readExternal method is invoked on this object's ref field.

If the external ref type name is "UnicastRef", "UnicastServerRef", "UnicastRef2", "UnicastServerRef2", or "ActivatableRef", a corresponding implementation-specific class must be found, and its readExternal method must read the serial data for that external ref type name as specified to be written in the serialData documentation for this class. If the external ref type name is any other string (of non-zero length), a ClassNotFoundException will be thrown, unless the implementation provides an implementation-specific class corresponding to that external ref type name, in which case this object's ref field will be set to an instance of that implementation-specific class.

Throws:

IOException

ClassNotFoundException

                         ClassNotFoundException

writeObject for custom serialization.

This method writes this object's serialized form for this class as follows:

The getRefClass method is invoked on this object's ref field to obtain its external ref type name. If the value returned by getRefClass was a non-null string of length greater than zero, the writeUTF method is invoked on out with the value returned by getRefClass, and then the writeExternal method is invoked on this object's ref field passing out as the argument; otherwise, the writeUTF method is invoked on out with a zero-length string (""), and then the writeObject method is invoked on out passing this object's ref field as the argument.

Serial Data:

The serialized data for this class comprises a string (written with ObjectOutput.writeUTF) that is either the external ref type name of the contained RemoteRef instance (the ref field) or a zero-length string, followed by either the external form of the ref field as written by its writeExternal method if the string was of non-zero length, or the serialized form of the ref field as written by passing it to the serialization stream's writeObject if the string was of zero length.

If this object is an instance of RemoteStub or RemoteObjectInvocationHandler that was returned from any of the UnicastRemoteObject.exportObject methods and custom socket factories are not used, the external ref type name is "UnicastRef". If this object is an instance of RemoteStub or RemoteObjectInvocationHandler that was returned from any of the UnicastRemoteObject.exportObject methods and custom socket factories are used, the external ref type name is "UnicastRef2". If this object is an instance of RemoteStub or RemoteObjectInvocationHandler that was returned from any of the java.rmi.activation.Activatable.exportObject methods, the external ref type name is "ActivatableRef". If this object is an instance of RemoteStub or RemoteObjectInvocationHandler that was returned from the RemoteObject.toStub method (and the argument passed to toStub was not itself a RemoteStub), the external ref type name is a function of how the remote object passed to toStub was exported, as described above. If this object is an instance of RemoteStub or RemoteObjectInvocationHandler that was originally created via deserialization, the external ref type name is the same as that which was read when this object was deserialized.

If this object is an instance of java.rmi.server.UnicastRemoteObject that does not use custom socket factories, the external ref type name is "UnicastServerRef". If this object is an instance of UnicastRemoteObject that does use custom socket factories, the external ref type name is "UnicastServerRef2".

Following is the data that must be written by the writeExternal method and read by the readExternal method of RemoteRef implementation classes that correspond to the each of the defined external ref type names:

For "UnicastRef":

• the hostname of the referenced remote object, written by DataOutput.writeUTF(String)
• the port of the referenced remote object, written by DataOutput.writeInt(int)
• the data written as a result of calling {link java.rmi.server.ObjID#write(java.io.ObjectOutput)} on the ObjID instance contained in the reference
• the boolean value false, written by DataOutput.writeBoolean(boolean)

For "UnicastRef2" with a null client socket factory:

• the byte value 0x00 (indicating null client socket factory), written by DataOutput.writeByte(int)
• the hostname of the referenced remote object, written by DataOutput.writeUTF(String)
• the port of the referenced remote object, written by DataOutput.writeInt(int)
• the data written as a result of calling {link java.rmi.server.ObjID#write(java.io.ObjectOutput)} on the ObjID instance contained in the reference
• the boolean value false, written by DataOutput.writeBoolean(boolean)

For "UnicastRef2" with a non-null client socket factory:

• the byte value 0x01 (indicating non-null client socket factory), written by DataOutput.writeByte(int)
• the hostname of the referenced remote object, written by DataOutput.writeUTF(String)
• the port of the referenced remote object, written by DataOutput.writeInt(int)
• a client socket factory (object of type java.rmi.server.RMIClientSocketFactory), written by passing it to an invocation of writeObject on the stream instance
• the data written as a result of calling {link java.rmi.server.ObjID#write(java.io.ObjectOutput)} on the ObjID instance contained in the reference
• the boolean value false, written by DataOutput.writeBoolean(boolean)

For "ActivatableRef" with a null nested remote reference:

• an instance of java.rmi.activation.ActivationID, written by passing it to an invocation of writeObject on the stream instance
• a zero-length string (""), written by DataOutput.writeUTF(String)

For "ActivatableRef" with a non-null nested remote reference:

• an instance of java.rmi.activation.ActivationID, written by passing it to an invocation of writeObject on the stream instance
• the external ref type name of the nested remote reference, which must be "UnicastRef2", written by DataOutput.writeUTF(String)
• the external form of the nested remote reference, written by invoking its writeExternal method with the stream instance (see the description of the external form for "UnicastRef2" above)

For "UnicastServerRef" and "UnicastServerRef2", no data is written by the writeExternal method or read by the readExternal method.

Throws:

IOException

ClassNotFoundException
