AudioMetadataMap

AudioMetadataMap is a writeable Map-style interface of AudioMetadata.Key value pairs.

A read only Map-style interface of AudioMetadata.Key value pairs used for AudioMetadata.

Using a AudioMetadata.Key interface, this map looks up the corresponding value. Read-only maps are thread-safe for lookup, but the underlying object values may need their own thread protection if mutable.

Summary

Public methods
abstract Boolean	`containsKey(key: AudioMetadata.Key<T>)` Returns true if the key exists in the map.
abstract AudioMetadataMap	`dup()` Returns a copy of the map.
abstract T?	`get(key: AudioMetadata.Key<T>)` Returns the value associated with the key.
abstract Int	`size()` Returns the number of elements in the map.

Public methods

containsKey

Added in API level 30

abstract fun <T : Any!> containsKey(key: AudioMetadata.Key<T>): Boolean

Returns true if the key exists in the map.

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

Return
`Boolean`	true if key exists in the Map.

dup

Added in API level 30

abstract fun dup(): AudioMetadataMap

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.

Return
`AudioMetadataMap`	a Map copied from the existing map. This value cannot be `null`.

get

Added in API level 30

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

Returns the value associated with the key.

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

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

size

Added in API level 30

abstract fun size(): Int

Returns the number of elements in the map.

Return
`Int`	Value is 0 or greater
