Examples of org.jamesii.gui.syntaxeditor.DocumentReader

org.jamesii.gui.syntaxeditor.DocumentReader
Implements a {@link Reader} using a {@link Document} as source. It providesthe option to actually track changes made to the document. This way this reader stays consistent even though the document gets changed while reading from it.
NOTE: Consistency in a memory friendly way can only be ensured if the supplied {@link Document} is a sub class of {@link AbstractDocument} andtherefore supports {@link DocumentFilter}s. Nevertheless the current implementation becomes memory unfriendly if any change occurs to the document while reading because to ensure consistency a copy of the old content is created if any change occurs. @author Stefan Rybacki
