com.ibm.lpex.core.LpexCommonParser
com.ibm.lpex.rexx.RexxParser
- All Implemented Interfaces:
- LpexConstants, LpexParser
- public class RexxParser
- extends LpexCommonParser
Document parser for REXX.
Actions and assigned keys added by this document parser:
- comment (Ctrl+/) - to comment out the current selection
- errors - for a selective view of the errors
- labels (Ctrl+G) - for a selective view of the labels in the document.
Keys already defined (e.g., by the active base profile) to an action
different from nullAction are not redefined in here.
Action modified by this document parser:
- contextHome - to skip comment-defining characters when determining
the start of the text.

supported.
- Parameters:
- lpexView - the LPEX document view associated with this parser
parseAll
public void parseAll()
- Total parse of the entire document.
- Specified by:
- parseAll in class LpexCommonParser

parseElement
public void parseElement(int element)
- Incremental parse.
- Specified by:
- parseElement in class LpexCommonParser
- Parameters:
- element - the element whose committed change triggered the parse,
or the element that precedes / follows a deleted block.
The parser may identify other neighbouring elements that
will have to be reparsed as a unit
- See Also:
- LpexView.parsePending(int),

Total and incremental parse
getProfile
public ResourceBundle getProfile()
- Returns the parser's properties profile resource bundle.
