public DistinctTypeListener(Set<String> visitedSet)

Method Details

enter

public ScanningMode enter(CtElement element)

Description copied from interface: CtScannerListener

Called before the scanner enters an element

Specified by:

enter in interface CtScannerListener

Parameters:

element - the element about to be scanned.

Returns:

a ScanningMode that drives how the scanner processes this element and its children. For instance, returning ScanningMode.SKIP_ALL causes that element and all children to be skipped and CtScannerListener.exit(CtElement) are be NOT called for that element.

exit

public void exit(CtElement element)

Description copied from interface: CtScannerListener

This method is called after the element and all its children have been visited. This method is NOT called if an exception is thrown in CtScannerListener.enter(CtElement) or during the scanning of the element or any of its children element. This method is NOT called for an element for which CtScannerListener.enter(CtElement) returned ScanningMode.SKIP_ALL.

Specified by:

exit in interface CtScannerListener

Parameters:

element - the element that has just been scanned.

enter

public ScanningMode enter(CtTypeReference<?> typeRef,
 boolean isClass)

Called before the scanner enters an type

Parameters:

typeRef - the type reference to be scanned.

isClass - true if type reference refers to class, false if it is an interface

Returns:

a ScanningMode that drives how the scanner processes this element and its children. For instance, returning ScanningMode.SKIP_ALL causes that element and all children to be skipped and CtScannerListener.exit(CtElement) are be NOT called for that element.

exit

public void exit(CtTypeReference<?> typeRef,
 boolean isClass)

This method is called after the element and all its children have been visited. This method is NOT called if an exception is thrown in CtScannerListener.enter(CtElement) or during the scanning of the element or any of its children element. This method is NOT called for an element for which CtScannerListener.enter(CtElement) returned ScanningMode.SKIP_ALL.

Parameters:

typeRef - the type reference that has just been scanned.

isClass - true if type reference refers to class, false if it is an interface
