Interface NestedDocumentHandler

- All Known Implementing Classes:
DefaultNestedDocumentHandler
public interface NestedDocumentHandler
Interface that is used to delegate the handling of nested documents (EPS files, data sections) in a PostScript document. The implementation receives a parser instance so it can step forward until the end of the nested document is reached at which point control is given back to the original consumer.It is suggested to use the more generally usable
DSCListener
instead. This interface may be deprecated in the future.
