*** ** * ** ***

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);  

}
