AudioMetadataMap

Kotlin |Java

interface AudioMetadataMap : AudioMetadataReadMap

android.media.AudioMetadataMap

AudioMetadataMap is a writeable Map-style interface of AudioMetadata.Key value pairs. This interface is not guaranteed to be thread-safe unless the underlying implementation for the AudioMetadataMap states it as thread safe. {@see AudioMetadataReadMap}

Summary

Public methods
abstract T?	`remove(key: AudioMetadata.Key<T>)` Removes the value associated with the key.
abstract T?	`set(key: AudioMetadata.Key<T>, value: T)` Sets a value for the key.

Inherited functions

From class AudioMetadataReadMap

`Boolean`	`containsKey(key: AudioMetadata.Key<T>)` Returns true if the key exists in the map.
`AudioMetadataMap`	`dup()` Returns a copy of the map. This is intended for safe conversion between a `AudioMetadataReadMap` interface and a `AudioMetadataMap` interface. Currently only simple objects are used for key values which means a shallow copy is sufficient.
`T?`	`get(key: AudioMetadata.Key<T>)` Returns the value associated with the key.
`Int`	`size()` Returns the number of elements in the map.

Public methods

remove

Added in API level 30

abstract fun <T : Any!> remove(key: AudioMetadata.Key<T>): T?

Removes the value associated with the key.

Parameters
`key`	AudioMetadata.Key<T>: interface for storing the value. This value cannot be `null`.
`<T>`	type of value.

Return
`T?`	the value of the key, null if it doesn't exist.

set

Added in API level 30

abstract fun <T : Any!> set(
    key: AudioMetadata.Key<T>, 
    value: T
): T?

Sets a value for the key.

Parameters
`key`	AudioMetadata.Key<T>: interface for storing the value. This value cannot be `null`.
`<T>`	type of value.
`value`	T: a non-null value of type T.

Return
`T?`	the previous value associated with key or null if it doesn't exist.
