class ClassHelper
extends Object

This class is a Helper for ClassNode and classes handling ClassNodes. It does contain a set of predefined ClassNodes for the most used types and some code for cached ClassNode creation and basic ClassNode handling

Method Detail

getUnwrapper

public static ClassNode getUnwrapper(ClassNode cn)

getWrapper

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 exmaple for boolean, the wrapper class is java.lang.Boolean. If the parameter is no primitve type, the redirected ClassNode will be returned
see:
#make(Class)
see:
#make(String)
param:
cn the ClassNode containing a possible primitive type

isCachedType

public static boolean isCachedType(ClassNode type)

isNumberType

public static boolean isNumberType(ClassNode cn)

isPrimitiveType

public static boolean isPrimitiveType(ClassNode cn)
Test to determine if a ClasNode is a primitve type. Note: this only works for ClassNodes created using a predefined ClassNode
see:
#make(Class)
see:
#make(String)
param:
cn the ClassNode containing a possible primitive type
return:
true if the ClassNode is a primitve type

make

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
see:
#make(Class)
param:
classes an array of classes used to create the ClassNodes
return:
an array of ClassNodes

make

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
param:
c class used to created the ClassNode
return:
ClassNode instance created from the given class

make

public static ClassNode make(Class c, boolean includeGenerics)

make

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
param:
name of the class the ClassNode is representing

makeCached

public static ClassNode makeCached(Class c)

makeReference

public static ClassNode makeReference()

makeWithoutCaching

public static ClassNode makeWithoutCaching(Class c)

makeWithoutCaching

public static ClassNode makeWithoutCaching(Class c, boolean includeGenerics)

makeWithoutCaching

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
see:
#make(String)
param:
name of the class the ClassNode is representing
