GenericDocument | Google Play services

Represents a document unit.

Documents contain structured data conforming to their AppSearchSchema type. Each document is uniquely identified by a namespace and a String ID within that namespace.

Documents are constructed by using the GenericDocument.Builder.

clone()

finalize()

getClass()

hashCode()

notify()

notifyAll()

toString()

wait(long arg0, int arg1)

wait(long arg0)

wait()

Creates a new GenericDocument from an existing instance.

This method should be only used by constructor of a subclass.

Retrieves the property value with the given path as Object.

A path can be a simple property name, such as those returned by getPropertyNames(). It may also be a dot-delimited path through the nested document hierarchy, with nested GenericDocument properties accessed via '.' and repeated properties optionally indexed into via [n].

For example, given the following GenericDocument:

     (Message) {
         from: "sender@example.com"
         to: [{
             name: "Albert Einstein"
             email: "einstein@example.com"
           }, {
             name: "Marie Curie"
             email: "curie@example.com"
           }]
         tags: ["important", "inbox"]
         subject: "Hello"
     }
 

Here are some example paths and their results:

• "from" returns "sender@example.com" as a String array with one element
• "to" returns the two nested documents containing contact information as a GenericDocument array with two elements
• "to[1]" returns the second nested document containing Marie Curie's contact information as a GenericDocument array with one element
• "to[1].email" returns "curie@example.com"
• "to[100].email" returns null as this particular document does not have that many elements in its "to" array.
• "to.email" aggregates emails across all nested documents that have them, returning ["einstein@example.com", "curie@example.com"] as a String array with two elements.

If you know the expected type of the property you are retrieving, it is recommended to use one of the typed versions of this method instead, such as getPropertyString(String) or getPropertyStringArray(String).

If the property was assigned as an empty array using one of the Builder#setProperty functions, this method will return an empty array. If no such property exists at all, this method returns null.

Note: If the property is an empty GenericDocument[] or byte[][], this method will return a null value in versions of Android prior to Android T. Starting in Android T it will return an empty array if the property has been set as an empty array, matching the behavior of other property types.

• The entry with the given path as an object or null if there is no such path. The returned object will be one of the following types: String[], long[], double[], boolean[], byte[][], GenericDocument[].

Retrieves a boolean property by path.

See getProperty(String) for a detailed description of the path syntax.

• The first boolean associated with the given path or default value false if there is no such value or the value is of a different type.

• The boolean[] associated with the given path, or null if no value is set or the value is of a different type.

Retrieves a byte[] property by path.

See getProperty(String) for a detailed description of the path syntax.

• The first byte[] associated with the given path or null if there is no such value or the value is of a different type.

• The byte[][] associated with the given path, or null if no value is set or the value is of a different type.

• The first GenericDocument associated with the given path or null if there is no such value or the value is of a different type.

• The GenericDocument[] associated with the given path, or null if no value is set or the value is of a different type.

Retrieves a double property by path.

See getProperty(String) for a detailed description of the path syntax.

• The first double associated with the given path or default value 0.0 if there is no such value or the value is of a different type.

• The double[] associated with the given path, or null if no value is set or the value is of a different type.

Retrieves a long property by path.

See getProperty(String) for a detailed description of the path syntax.

• The first long associated with the given path or default value 0 if there is no such value or the value is of a different type.

• The long[] associated with the given path, or null if no value is set or the value is of a different type.

Returns the names of all properties defined in this document.

• The first String associated with the given path or null if there is no such value or the value is of a different type.

• The String[] associated with the given path, or null if no value is set or the value is of a different type.
