public Cursor(int type)

Creates a new cursor object with the specified type.

Parameters:

type - the type of cursor

Throws:

IllegalArgumentException - if the specified cursor type is invalid

protected Cursor(String name)

Creates a new custom cursor object with the specified name.

Note: this constructor should only be used by AWT implementations as part of their support for custom cursors. Applications should use Toolkit.createCustomCursor().

Parameters:

name - the user-visible name of the cursor.

Toolkit.createCustomCursor(java.awt.Image, java.awt.Point, java.lang.String)

public static Cursor getPredefinedCursor(int type)

Returns a cursor object with the specified predefined type.

Parameters:

type - the type of predefined cursor

Returns:

the specified predefined cursor

Throws:

IllegalArgumentException - if the specified cursor type is invalid

public static Cursor getSystemCustomCursor(String name)
                                    throws AWTException,
                                           HeadlessException

Returns a system-specific custom cursor object matching the specified name. Cursor names are, for example: "Invalid.16x16"

Parameters:

name - a string describing the desired system-specific custom cursor

Returns:

the system specific custom cursor named

Throws:

HeadlessException - if GraphicsEnvironment.isHeadless returns true

AWTException

public static Cursor getDefaultCursor()

Return the system default cursor.

public int getType()

Returns the type for this cursor.

public String getName()

Returns the name of this cursor.

Returns:

a localized description of this cursor.

Since:

1.2

public String toString()

Returns a string representation of this cursor.

Overrides:

toString in class Object

Returns:

a string representation of this cursor.

Since:

1.2

protected void finalize()
                 throws Throwable

Description copied from class: Object

Called by the garbage collector on an object when garbage collection determines that there are no more references to the object. A subclass overrides the finalize method to dispose of system resources or to perform other cleanup.

The general contract of finalize is that it is invoked if and when the Java^TM virtual machine has determined that there is no longer any means by which this object can be accessed by any thread that has not yet died, except as a result of an action taken by the finalization of some other object or class which is ready to be finalized. The finalize method may take any action, including making this object available again to other threads; the usual purpose of finalize, however, is to perform cleanup actions before the object is irrevocably discarded. For example, the finalize method for an object that represents an input/output connection might perform explicit I/O transactions to break the connection before the object is permanently discarded.

The finalize method of class Object performs no special action; it simply returns normally. Subclasses of Object may override this definition.

The Java programming language does not guarantee which thread will invoke the finalize method for any given object. It is guaranteed, however, that the thread that invokes finalize will not be holding any user-visible synchronization locks when finalize is invoked. If an uncaught exception is thrown by the finalize method, the exception is ignored and finalization of that object terminates.

After the finalize method has been invoked for an object, no further action is taken until the Java virtual machine has again determined that there is no longer any means by which this object can be accessed by any thread that has not yet died, including possible actions by other objects or classes which are ready to be finalized, at which point the object may be discarded.

The finalize method is never invoked more than once by a Java virtual machine for any given object.

Any exception thrown by the finalize method causes the finalization of this object to be halted, but is otherwise ignored.

Overrides:

finalize in class Object

Throws:

Throwable - the Exception raised by this method
