Method Detail

• public static MethodNode findSAM(ClassNode type)

  Returns the single abstract method of a class node, if it is a SAM type, or null otherwise.

  Parameters:

  type - a type for which to search for a single abstract method

  Returns:

  the method node if type is a SAM type, null otherwise

• public static ClassNode getNextSuperClass(ClassNode clazz, ClassNode goalClazz)

  Returns a super class or interface for a given class depending on a given target. If the target is no super class or interface, then null will be returned. For a non-primitive array type, returns an array of the componentType's super class or interface if the target is also an array.

  Parameters:

  clazz - the start class

  goalClazz - the goal class

  Returns:

  the next super class or interface

• public static ClassNode getUnwrapper(ClassNode cn)

• public static ClassNode getWrapper(ClassNode cn)

  Creates a ClassNode containing the wrapper of a ClassNode of primitive type. Any ClassNode representing a primitive type should be created using the predefined types used in class. The method will check the parameter for known references of ClassNode representing a primitive type. If Reference is found, then a ClassNode will be contained that represents the wrapper class. For example for boolean, the wrapper class is java.lang.Boolean.

  If the parameter is no primitive type, the redirected ClassNode will be returned

  Parameters:

  cn - the ClassNode containing a possible primitive type

  make(Class)

  make(String)

• public static boolean isCachedType(ClassNode type)

• public static boolean isFunctionalInterface(ClassNode type)

• public static boolean isGeneratedFunction(ClassNode type)

  Checks if the type is a generated function, i.e. closure or lambda.

  Since:

  3.0.0

• public static boolean isNumberType(ClassNode cn)

• public static boolean isPrimitiveType(ClassNode cn)

  Test to determine if a ClassNode is a primitive type. Note: this only works for ClassNodes created using a predefined ClassNode

  Parameters:

  cn - the ClassNode containing a possible primitive type

  Returns:

  true if the ClassNode is a primitive type

  See Also:

  make(Class)

  make(String)

• public static boolean isSAMType(ClassNode type)

• public static boolean isStaticConstantInitializerType(ClassNode cn)

  Test to determine if a ClassNode is a type belongs to the list of types which are allowed to initialize constants directly in bytecode instead of using <cinit>

  Note: this only works for ClassNodes created using a predefined ClassNode

  Parameters:

  cn - the ClassNode to be tested

  Returns:

  true if the ClassNode is of int, float, long, double or String type

  make(Class)

  make(String)

• public static ClassNode[] make(Class[] classes)

  Creates an array of ClassNodes using an array of classes. For each of the given classes a new ClassNode will be created

  Parameters:

  classes - an array of classes used to create the ClassNodes

  Returns:

  an array of ClassNodes

  See Also:

  make(Class)

• public static ClassNode make(Class c)

  Creates a ClassNode using a given class. A new ClassNode object is only created if the class is not one of the predefined ones

  Parameters:

  c - class used to created the ClassNode

  Returns:

  ClassNode instance created from the given class

• public static ClassNode make(Class c, boolean includeGenerics)

• public static ClassNode make(String name)

  Creates a ClassNode using a given class. If the name is one of the predefined ClassNodes then the corresponding ClassNode instance will be returned. If the name is null or of length 0 the dynamic type is returned

  Parameters:

  name - of the class the ClassNode is representing

• public static ClassNode makeCached(Class c)

• public static ClassNode makeReference()

• public static ClassNode makeWithoutCaching(Class c)

• public static ClassNode makeWithoutCaching(Class c, boolean includeGenerics)

• public static ClassNode makeWithoutCaching(String name)

  Creates a ClassNode using a given class. Unlike make(String) this method will not use the cache to create the ClassNode. This means the ClassNode created from this method using the same name will have a different reference

  Parameters:

  name - of the class the ClassNode is representing
