modifyEvent in interface EditorListenertopLine - Topmost modified line of text.public void startParsing(int lno)

startParsing in interface RegionHandlerlno - Start line numberpublic void endParsing(int lno)
RegionHandler
endParsing in interface RegionHandlerlno - End line number
public void clearLine(int lno,
java.lang.String line)
RegionHandler
clearLine in interface RegionHandlerlno - Line number
public void addRegion(int lno,
java.lang.String line,
int sx,
int ex,
Region region)
RegionHandler
addRegion in interface RegionHandlerlno - Current line numbersx - Start X position of region in lineex - End X position of region in lineregion - Region information
public void enterScheme(int lno,
java.lang.String line,
int sx,
int ex,
Region region,
java.lang.String scheme)
RegionHandlerregion is used to specify
scheme background region information.
If text is parsed not from the first line, this method is called
with fake parameters to compensate required scheme structure.
enterScheme in interface RegionHandlerlno - Current line numbersx - Start X position of region in lineex - End X position of region in lineregion - Scheme Region information (background)scheme - Additional Scheme information
public void leaveScheme(int lno,
java.lang.String line,
int sx,
int ex,
Region region,
java.lang.String scheme)
RegionHandlerregion is used to specify
scheme background region information.
If text parse process ends, but current schemes stack is not balanced
(this can happends because of bad balanced structure of source text,
or partial text parse) this method is not called for unbalanced
levels.
