Specified by:

initializeDocument in interface IlvDocument

Overrides:

initializeDocument in class IlvAbstractDocument

Parameters:

userData - The user data to initialize the document with; can be null.

Returns:

true: an overridden method returns true if the document was successfully initialized, false otherwise.

clean

public void clean()

readDocument

protected boolean readDocument(Reader reader,
                               IlvFileFilter filter)

Reads the text of the document data from the specified reader. If a javax.swing.text.Document instance has not been initialized for the document, it is created with the method createTextDocument() and initialized with the method initializeTextDocument(javax.swing.text.Document).
This text read from the specified reader is then set to this javax.swing.text.Document instance.

Overrides:

readDocument in class IlvAbstractFileDocument

Parameters:

reader - The reader to read document text from.

filter - Parameter not used by default.

Returns:

true if the document could read its data; false otherwise.

See Also:
