interface AudioMetadataMap : AudioMetadataReadMap
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? |
Removes the value associated with the key.
|
| abstract T? |
Sets a value for the key.

Public methods
remove
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
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. |
