public AnnotationDB()

Method Detail

getAnnotationIndex

public Map<String,Set<String>> getAnnotationIndex()

returns a map keyed by the fully qualified string name of a annotation class. The Set returne is a list of classes that use that annotation somehow.

getClassIndex

public Map<String,Set<String>> getClassIndex()

returns a map keyed by the list of classes scanned. The value set returned is a list of annotations used by that class.

getInterfacesIndex

public Map<String,Set<String>> getInterfacesIndex()

Returns:

setScanMethodAnnotations

public void setScanMethodAnnotations(boolean scanMethodAnnotations)

Wheter or not you want AnnotationDB to scan for method level annotations

Parameters:

scanMethodAnnotations -

setScanParameterAnnotations

public void setScanParameterAnnotations(boolean scanParameterAnnotations)

Whether or not you want AnnotationDB to scan for parameter level annotations

Parameters:

scanParameterAnnotations -

setScanFieldAnnotations

public void setScanFieldAnnotations(boolean scanFieldAnnotations)

Whether or not you want AnnotationDB to scan for parameter level annotations

Parameters:

scanFieldAnnotations -

scanArchives

public void scanArchives()

Scan a url that represents an "archive" this is a classpath directory or jar file

Parameters:

urls - variable list of URLs to scan as archives

resetScanner

public void resetScanner()

Specified by:
