Returns the current phase.

getPhaseDescription

public String getPhaseDescription()

Returns the description for the current phase.

getErrorCollector

public ErrorCollector getErrorCollector()

Errors found during the compilation should be reported through the ErrorCollector.

Returns:

the ErrorCollector for this ProcessingUnit

completePhase

public void completePhase()
                   throws CompilationFailedException
