Abstract:
A method in a data processing system for generating a metadata stream, the method comprising the data processing system implemented steps of:receiving an attribute call to set an attribute; querying a first group of attributes to determine whether the attribute call is present in the first group of attributes; updating the first group of attributes in response to the attribute call being absent in the first group of attributes; receiving a primitive call; erasing all attribute calls stored in a second group of attributes in response to the primitive call being a call for a new section; retrieving an attribute call associated with the primitive from the first group of attributes; determining whether the attribute call associated with the primitive is present in a second group of attributes; updating the second group of attributes to include the attribute call associated with the primitive call in response to the attribute call associated with the primitive call being absent in the second group of attributes; placing the attribute call associated with the primitive call in the metadata stream in response to updating the second group of attributes; and placing the primitive call in the metadata stream.
