box

public void box(org.objectweb.asm.Type type)

If the argument is a primitive class, replaces the primitive value on the top of the stack with the wrapped (Object) equivalent. For example, char -> Character. If the class is Void, a null is pushed onto the stack instead.

Parameters:

type - the class indicating the current type of the top stack value

unbox

public void unbox(org.objectweb.asm.Type type)

If the argument is a primitive class, replaces the object on the top of the stack with the unwrapped (primitive) equivalent. For example, Character -> char.

Parameters:

type - the class indicating the desired type of the top stack value

create_arg_array

public void create_arg_array()

Allocates and fills an Object[] array with the arguments to the current method. Primitive values are inserted as their boxed (Object) equivalents.

zero_or_null

public void zero_or_null(org.objectweb.asm.Type type)

Pushes a zero onto the stack if the argument is a primitive class, or a null otherwise.

unbox_or_zero

public void unbox_or_zero(org.objectweb.asm.Type type)

Unboxes the object on the top of the stack. If the object is null, the unboxed primitive value becomes zero.

public void visitMaxs(int maxStack,
                      int maxLocals)

Overrides:
