Constructor Detail

OutOnly

public OutOnly(Parameter ref)

Constructs a new pointer to a given object. The constructed pointer is a non-null pointer parameter that points to the memory area big enough to hold the given object.

Parameters:

ref - referenced object.

public OutOnly(java.lang.Class parameterClass)

Method Detail

clone

public java.lang.Object clone()

Overrides:

clone in class Pointer

write

public void write(DataBuffer stackBuffer,
                  int offset,
                  boolean invokedByCallback)
           throws MemoryAccessViolationException

Description copied from class: Parameter

Writes this parameter to a specified data source.

Overrides:

write in class Pointer

Throws:

MemoryAccessViolationException

push

public void push(DataBuffer stackBuffer,
                 int offset,
                 boolean invokedByCallback)

Description copied from class: Parameter

Writes a parameter to a function stacks.

Overrides:

push in class Pointer

pop

public void pop(DataBuffer stackBuffer,
                int offset,
                boolean invokedByCallback)
         throws MemoryAccessViolationException

Description copied from class: Parameter

Default implementation that does nothing because most primitive types do nothing on pop. Reads a parameter from a function stack.

Overrides:

pop in class Pointer

Throws:

MemoryAccessViolationException
