Method Detail

getRoleHandler

public static RoleHandler getRoleHandler(java.lang.Class<? extends CtElement> targetClass,
                                         CtRole role)

Parameters:

targetClass - the class of the to be manipulated node

role - defines the to be manipulated attribute

Returns:

RoleHandler implementation which knows how to manipulate the attribute of CtRole on `targetClass` or throws exception if such role doesn't exist on the `targetClass`

getOptionalRoleHandler

public static RoleHandler getOptionalRoleHandler(java.lang.Class<? extends CtElement> targetClass,
                                                 CtRole role)

Parameters:

targetClass - the Class of the to be manipulated node

role - defines the to be manipulated attribute

Returns:

RoleHandler implementation, which knows how to manipulate the attribute of CtRole on `targetClass` or returns null if such role doesn't exist on the `targetClass`

getRoleHandlers

public static java.util.List<RoleHandler> getRoleHandlers(java.lang.Class<? extends CtElement> targetClass)

Parameters:

targetClass - a Class whose handlers we are looking for

Returns:

all RoleHandlers available for the `targetClass`

forEachRoleHandler

public static void forEachRoleHandler(java.util.function.Consumer<RoleHandler> consumer)

Parameters:

consumer - is called for each RoleHandler of SpoonModel

getRoleHandlerWrtParent

public static RoleHandler getRoleHandlerWrtParent(CtElement element)

Parameters:

element - the CtElement whose relation from `element.getParent()` to `element` is needed.

Returns:

RoleHandler handling relation from `element.getParent()` to `element`
