abstract class RTFReader.AttributeTrackingDestination

extends Object

implements RTFReader.Destination

RTFReader.TextHandlingDestination is an abstract RTF destination which simply tracks the attributes specified by the RTF control words in internal form and can produce acceptable AttributeSets for the current character, paragraph, and section attributes. It is up to the subclasses to determine what is done with the actual text.
