interface AudioMetadataReadMap
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.
{@see AudioMetadataMap}
Summary
| Public methods |
| abstract Boolean |
Returns true if the key exists in the map.
|
| abstract AudioMetadataMap |
Returns a copy of the map.
|
| abstract T? |
Returns the value associated with the key.
|
| abstract Int |
Returns the number of elements in the map.
|
Public methods
containsKey
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
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
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
abstract fun size(): Int
Returns the number of elements in the map.
| Return |
Int |
Value is 0 or greater |
