java.lang.Objectorg.eclipse.ocl.util.ProblemHandlerWrapper
public class ProblemHandlerWrapper
A wrapper for ProblemHandlers, convenient for subclassing to
decorate/intercept an existing problem handler instance.
| Nested Class Summary | |
|---|---|
static class |
ProblemHandlerWrapper.Tee
Like the UNIX tool tee, a Tee forks problem handling in two directions, that is, to two other problem-handler instances. |

ProblemHandlerWrapper(ProblemHandler delegate)
Initializes me with the problem-handler to which I delegate. |
|
| Method Summary | |
|---|---|
void |
analyzerProblem(ProblemHandler.Severity problemSeverity,
String problemMessage,
String processingContext,
int startOffset,
int endOffset)
Convenience method typically invoking handleProblem
with a analyzerProblem processing phase. |
void |
beginParse()
Notifies me that parsing is about to begin, from which I may receive problems. |
void |
beginValidation()
Notifies me that validation is about to begin, from which I may receive problems. |
void |
endParse()
Notifies me that parsing has completed, and I will get no further problems in this session. |
void |
endValidation()
Notifies me that validation has completed, and I will get no further problems in this session. |
void |
flush(Monitor monitor)
Flush all problems to their recipient. |
int |
getErrorReportLineOffset()
Queries the line offset for reporting errors. |
AbstractParser |
getParser()
Queries the parser from which I obtain source tokens and text. |
void |
handleProblem(ProblemHandler.Severity problemSeverity,
ProblemHandler.Phase processingPhase,
String problemMessage,
String processingContext,
int startOffset,
int endOffset)
Handle a problem of problemSeverity that has arisen during processingPhase and which is explained by problemMessage optionally clarified, if non-null, by processingContext, and if non-negative by the startOffset and endOffset character indexes in the parsing stream. |
void |
lexerProblem(ProblemHandler.Severity problemSeverity,
String problemMessage,
String processingContext,
int startOffset,
int endOffset)
Convenience method typically invoking handleProblem
with a lexerProblem processing phase. |
void |
parserProblem(ProblemHandler.Severity problemSeverity,
String problemMessage,
String processingContext,
int startOffset,
int endOffset)
Convenience method typically invoking handleProblem
with a parserProblem processing phase. |
void |
setErrorReportLineOffset(int offset)
Sets the line offset for reporting errors. |
void |
setParser(AbstractParser parser)
Define the syntactic parser from which source tokens and text may be obtained. |
void |
utilityProblem(ProblemHandler.Severity problemSeverity,
String problemMessage,
String processingContext,
int startOffset,
int endOffset)
Convenience method typically invoking handleProblem
with a utilityProblem processing phase. |
void |
validatorProblem(ProblemHandler.Severity problemSeverity,
