Method Detail

getProcessor

AnnotationProcessor getProcessor()

Returns the AnnotationProcessor instance this context is associated with.

Returns:

annotation processor instance

getProcessingInput

Scanner getProcessingInput()

Returns the Scanner implementation which is responsible for providing access to all the .class files the processing tool needs to scan.

Returns:

scanner instance

getArchive

org.glassfish.api.deployment.archive.ReadableArchive getArchive()

Returns the module archive that can be used to load files/resources, that assist in the processing of annotations. Using the ClassLoader is preferred, but not all files can be loaded by it and this can be handy in those cases.

Returns:

module archive

setArchive

void setArchive(org.glassfish.api.deployment.archive.ReadableArchive archive)

setProcessingInput

void setProcessingInput(Scanner scanner)

Sets the Scanner implementation which is responsible for accessing all the .class files the AnnotationProcessor should process.

pushHandler

void pushHandler(AnnotatedElementHandler handler)

Push a new handler on the stack of handlers. This handler will receive all the AnnotedElementHandler events until it is removed from the stack with a popHandler() call.

Parameters:

handler - the new events handler.

getHandler

AnnotatedElementHandler getHandler()

Return the current handler (if any) receving all the annotated elements start and stop events.

Returns:

the top handler

popHandler

AnnotatedElementHandler popHandler()

Removes the top handler

Returns:

the removed handler

getHandler

<U extends AnnotatedElementHandler> U getHandler(Class<U> handlerType)
                                          throws ClassCastException

Return the top handler casted to the requested handler type

Parameters:

requested - handler type

Returns:

the top handler

Throws:

ClassCastException - if the top handler cannot be casted to the requested handler type.

setErrorHandler

void setErrorHandler(ErrorHandler errorHandler)

Sets the ErrorHandler instance for all errors/warnings that may be raised during the annotation processing.

Parameters:

handler - the annotation handler

getErrorHandler

ErrorHandler getErrorHandler()

Return the error handler for this processing context.

Returns:

the error handler
