Class RTFReader.TextHandlingDestination

java.lang.Object
  javax.swing.text.rtf.RTFReader.AttributeTrackingDestination
      javax.swing.text.rtf.RTFReader.TextHandlingDestination

All Implemented Interfaces:

RTFReader.Destination

Direct Known Subclasses:

RTFReader.DocumentDestination

Enclosing class:

RTFReader

abstract class RTFReader.TextHandlingDestination

extends RTFReader.AttributeTrackingDestination

implements RTFReader.Destination

RTFReader.TextHandlingDestination provides basic text handling functionality. Subclasses must implement:

deliverText()

to handle a run of text with the same attributes

finishParagraph()

to end the current paragraph and set the paragraph's attributes

endSection()

to end the current section
