Parameters:

desc - original descriptor

Returns:

copy of the given descriptor

isValid

public static boolean isValid(OperatorDescriptor descriptor)

Checks if the given descriptor has an associated class file.

Parameters:

descriptor - operator descriptor

Returns:

true, if the descriptor is valid, false instead

locateDescriptor

public static java.net.URI locateDescriptor(java.lang.Class clazz)

Locates a descriptor for the given class.

Parameters:

clazz - class

Returns:

URI poiting to the descriptor or null if no descriptor has been found

locateDescriptor

public static java.net.URI locateDescriptor(java.lang.String className)

Locates a descriptor for the given class.

Parameters:

className - name of the class

Returns:

URI poiting to the descriptor or null if no descriptor has been found

locateDescriptor

public static java.net.URI locateDescriptor(java.lang.String className,
                                            java.lang.ClassLoader loader)

Locates a descriptor for a given class by using the provided class loader.

resolve

public static void resolve(AttributeDescriptor ad,
                           java.lang.Class clazz)

Resolves the given attribute descriptor.

Parameters:

ad - descriptor to be resolved

clazz - class that is the parent of the property to be resolved

Parameters:

descriptor - operator descriptor to be resolved

loader - class loader to be used for resolving
