setCompileErrorHandler

public void setCompileErrorHandler(ErrorHandler optionalCompileErrorHandler)(Code)

By default, CompileException s are thrown on compile errors, but an application my install its own (thread-local) ErrorHandler .

Be aware that a single problem during compilation often causes a bunch of compile errors, so a good ErrorHandler counts errors and throws a CompileException when a limit is reached.

If the given ErrorHandler does not throw CompileException s, then UnitCompiler.compileUnit(EnumeratorSet) will throw one when the compilation of the unit is finished, and errors had occurred. In other words: The ErrorHandler may throw a CompileException or not, but UnitCompiler.compileUnit(EnumeratorSet) will definitely throw a CompileException if one or more compile errors have occurred.
Parameters:
optionalCompileErrorHandler - null to restore the default behavior (throwing a CompileException

setWarningHandler
