Public constructors

Topic

Added in API level 34
Also in Ad Services Extensions 4

public Topic (long mTaxonomyVersion, 
                long mModelVersion, 
                int mTopicId)

Creates an object which represents the result from the getTopics API.

Parameters
`mTaxonomyVersion`	`long`: a long representing the version of the taxonomy.
`mModelVersion`	`long`: a long representing the version of the model.
`mTopicId`	`int`: an integer representing the unique id of a topic.

Public methods

equals

Added in API level 34

public boolean equals (Object object)

Indicates whether some other object is "equal to" this one.

The equals method implements an equivalence relation on non-null object references:

It is reflexive: for any non-null reference value x, x.equals(x) should return true.
It is symmetric: for any non-null reference values x and y, x.equals(y) should return true if and only if y.equals(x) returns true.
It is transitive: for any non-null reference values x, y, and z, if x.equals(y) returns true and y.equals(z) returns true, then x.equals(z) should return true.
It is consistent: for any non-null reference values x and y, multiple invocations of x.equals(y) consistently return true or consistently return false, provided no information used in equals comparisons on the objects is modified.
For any non-null reference value x, x.equals(null) should return false.

An equivalence relation partitions the elements it operates on into equivalence classes; all the members of an equivalence class are equal to each other. Members of an equivalence class are substitutable for each other, at least for some purposes.

Parameters
`object`	`Object`: the reference object with which to compare.

Returns
`boolean`	`true` if this object is the same as the obj argument; `false` otherwise.

getModelVersion

Added in API level 34
Also in Ad Services Extensions 4

public long getModelVersion ()

Get the ModelVersion.

Returns
`long`

getTaxonomyVersion

Added in API level 34
Also in Ad Services Extensions 4

public long getTaxonomyVersion ()

Get the TaxonomyVersion.

Returns
`long`

getTopicId

Added in API level 34
Also in Ad Services Extensions 4

public int getTopicId ()

Get the Topic ID.

Returns
`int`

hashCode

Added in API level 34

public int hashCode ()

Returns a hash code value for the object. This method is supported for the benefit of hash tables such as those provided by HashMap.

The general contract of hashCode is:

Whenever it is invoked on the same object more than once during an execution of a Java application, the hashCode method must consistently return the same integer, provided no information used in equals comparisons on the object is modified. This integer need not remain consistent from one execution of an application to another execution of the same application.
If two objects are equal according to the equals method, then calling the hashCode method on each of the two objects must produce the same integer result.
It is not required that if two objects are unequal according to the equals method, then calling the hashCode method on each of the two objects must produce distinct integer results. However, the programmer should be aware that producing distinct integer results for unequal objects may improve the performance of hash tables.

Returns
`int`	a hash code value for this object.

toString

Added in API level 34

public String toString ()

Returns a string representation of the object.

Returns
`String`	a string representation of the object.
