Method Detail

getMetaDataForClass

public AbstractClassMetaData getMetaDataForClass(java.lang.Class cls,
                                                 PackageMetaData pmd,
                                                 ClassLoaderResolver clr)

Accessor for the MetaData for the specified class, read from annotations. The annotations can be of any supported type.

Specified by:

getMetaDataForClass in interface AnnotationManager

Parameters:

cls - The class

pmd - PackageMetaData to use as a parent

clr - ClassLoader resolver

Returns:

The ClassMetaData

getClassAnnotationHasHandler

public boolean getClassAnnotationHasHandler(java.lang.String annotationName)

Specified by:

getClassAnnotationHasHandler in interface AnnotationManager

getMemberAnnotationHasHandler

public boolean getMemberAnnotationHasHandler(java.lang.String annotationName)

Specified by:

getMemberAnnotationHasHandler in interface AnnotationManager

getHandlerForClassAnnotation

public ClassAnnotationHandler getHandlerForClassAnnotation(java.lang.String annotationName)

Description copied from interface: AnnotationManager

Accessor for a handler for the specified class annotation.

Specified by:

getHandlerForClassAnnotation in interface AnnotationManager
