public interface AudioMetadataReadMap

AudioMetadataMap

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 <T> boolean`	`containsKey(Key<T> key)` Returns true if the key exists in the map.
`abstract AudioMetadataMap`	`dup()` Returns a copy of the map.
`abstract <T> T`	`get(Key<T> key)` 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

public abstract boolean containsKey (Key<T> key)

Returns true if the key exists in the map.

Parameters
`key`	`Key`: interface for requesting the value. This value cannot be `null`.

Returns
`boolean`	true if key exists in the Map.

dup

Added in API level 30

public abstract 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.

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

get

Added in API level 30

public abstract T get (Key<T> key)

Returns the value associated with the key.

Parameters
`key`	`Key`: interface for requesting the value. This value cannot be `null`.

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

size

Added in API level 30

public abstract int size ()

Returns the number of elements in the map.

Returns
`int`	Value is 0 or greater
