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 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
See Also:
make(Class)
make(String)

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 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)

isStaticConstantInitializerType

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
See Also:
make(Class)
make(String)

make

public static ClassNode[] make(java.lang.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)

make

public static ClassNode make(java.lang.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

make

public static ClassNode make(java.lang.Class c, boolean includeGenerics)

make

public static ClassNode make(java.lang.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

makeCached

public static ClassNode makeCached(java.lang.Class c)

makeReference

public static ClassNode makeReference()

makeWithoutCaching

public static ClassNode makeWithoutCaching(java.lang.Class c)

makeWithoutCaching

public static ClassNode makeWithoutCaching(java.lang.Class c, boolean includeGenerics)

makeWithoutCaching

public static ClassNode makeWithoutCaching(java.lang.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
See Also:
make(String)
