Methods Summary
public java.lang.String	getKeyValue(java.lang.String key) Retrieve the value found in the metadata associated with the given key. Only keys obtained from getKeys are valid and can be used to retrieve metadata values. If null or an invalid key is used, an IllegalArgumentException will be thrown. Some keys are valid but the associated metadata may not be available before a certain portion of the media is played. For example, some streaming media types may contain metadata that's stored at the end of the file. As a result, the metadata may not be available until the playback reaches the end of media. When that happens, calling getKeyValues with those keys will return null before the data is available. However, when the playback reaches the end of media, all metadata values must be made available. param key a key to retrieve the value. return the value of the key or null if the given key is valid but the value is not yet available. exception IllegalArgumentException Thrown if the given key is null or invalid.
