Method Detail

open

public void open(java.lang.String qualifiedClassname,
                 java.lang.ClassLoader cl)

Using the provided class loader, load the class so that it can be passed to a bytecode manipulation library.

Specified by:

open in interface AttributeExtractor

Parameters:

qualifiedClassname - The fully qualified classname - contains package information, ie java.lang.String

cl - Classloader to use to load the class.

close

public void close()

Close any resouces that were opened.

Specified by:

close in interface AttributeExtractor

getClassAttributes

public Attribute[] getClassAttributes()

Description copied from interface: AttributeExtractor

Retreives attributes associated with the class.

Specified by:

getClassAttributes in interface AttributeExtractor

Returns:

An array of attributes that satisfy the instanceof comparison with the filter class. Null if there are no attributes associated with the class.

getClassAttributes

public Attribute[] getClassAttributes(java.lang.Class filter)

Description copied from interface: AttributeExtractor

Retrieves attributes associated with the class of a given type.

Specified by:

getClassAttributes in interface AttributeExtractor

Parameters:

filter - The class object used to filter the returned attribute classes.

Returns:

An array of attributes that satisfy the instanceof comparison with the filter class.

getCustomClassAttributes

public java.lang.Object[] getCustomClassAttributes()

Retreives custom attributes applied to the class.

Returns:

An array of custom attributes. Null if there are no attributes.

getCustomClassAttributes

public java.lang.Object[] getCustomClassAttributes(java.lang.Object filter)

Return the list (possible empty) of attribute associated with the class that instances of the 'filter' class.

Parameters:

filter - The instance that will filter out only matching class types.
