Description copied from interface: ProblemHandler

Convenience method typically invoking handleProblem with a analyzerProblem processing phase.

Specified by:

analyzerProblem in interface ProblemHandler

Overrides:

Parameters:

problemSeverity - text describing the problem severity

problemMessage - message describing the problem

endOffset - (exclusive) index of last source character influencing the problem, -ve if unknown

beginParse

public void beginParse()

Description copied from interface: ProblemHandler

Notifies me that parsing is about to begin, from which I may receive problems. I should initialize myself accordingly, if necessary.

Specified by:

public void beginValidation()

Description copied from interface: ProblemHandler

Notifies me that validation is about to begin, from which I may receive problems. I should initialize myself accordingly, if necessary.

Specified by:

beginValidation in interface ProblemHandler

Overrides:

endParse in interface ProblemHandler

Overrides:

Flush all problems to their recipient. This method allows handlers to batch up error reports into a single composite report or transaction.

Specified by:

flush in interface ProblemHandler

Overrides:

flush in class ProblemHandlerWrapper

Parameters:

monitor - an optional EMF monitor for reporting progress. May be null if not needed by the caller

handleProblem

public void handleProblem(ProblemHandler.Severity problemSeverity,

                          String problemMessage,
                          String processingContext,
                          int startOffset,
                          int endOffset)

Description copied from interface: ProblemHandler

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. All other problem handling messages should redirect to this method.

Specified by:

handleProblem in interface ProblemHandler

Overrides:

handleProblem in class ProblemHandlerWrapper

Parameters:

problemSeverity - text describing the problem severity (e.g. errorSeverity)

processingPhase - optional text describing the processing phase (e.g. analyzerProblem)
