DrmUtils.ExtendedMetadataParser

Kotlin |Java

public static class DrmUtils.ExtendedMetadataParser
extends Object

java.lang.Object
↳	android.drm.DrmUtils.ExtendedMetadataParser

Utility that parses extended metadata embedded in DRM constraint information.

Usage example:

byte[] extendedMetadata
     = constraints.getAsByteArray(DrmStore.ConstraintsColumns.EXTENDED_METADATA);
ExtendedMetadataParser parser = getExtendedMetadataParser(extendedMetadata);
Iterator keyIterator = parser.keyIterator();
while (keyIterator.hasNext()) {
    String extendedMetadataKey = keyIterator.next();
    String extendedMetadataValue = parser.get(extendedMetadataKey);
}

Summary

Public methods
`String`	`get(String key)` This method retrieves the metadata value associated with a given key.
`Iterator<String>`	`iterator()` This method returns an iterator object that can be used to iterate over all values of the metadata.
`Iterator<String>`	`keyIterator()` This method returns an iterator object that can be used to iterate over all keys of the metadata.

From class


        
          java.lang.Object

`Object`	`clone()` Creates and returns a copy of this object.
`boolean`	`equals(Object obj)` Indicates whether some other object is "equal to" this one.
`void`	`finalize()` Called by the garbage collector on an object when garbage collection determines that there are no more references to the object.
`final Class<?>`	`getClass()` Returns the runtime class of this `Object`.
`int`	`hashCode()` Returns a hash code value for the object.
`final void`	`notify()` Wakes up a single thread that is waiting on this object's monitor.
`final void`	`notifyAll()` Wakes up all threads that are waiting on this object's monitor.
`String`	`toString()` Returns a string representation of the object.
`final void`	`wait(long timeoutMillis, int nanos)` Causes the current thread to wait until it is awakened, typically by being notified or interrupted, or until a certain amount of real time has elapsed.
`final void`	`wait(long timeoutMillis)` Causes the current thread to wait until it is awakened, typically by being notified or interrupted, or until a certain amount of real time has elapsed.
