Constructor Detail

Const

public Const(Parameter ref)

Constructs a new pointer to a given object. The constructed pointer is a non-null pointer parameter that points to the given object.

Parameters:

ref - referenced object.

Const

public Const(Parameter ref,
             boolean isNull)

Constructs a new pointer to a given object. The constructed pointer may be nul, in which case a referenced object value is not used or updated until the pointer value is changed to non-null by native function.

Parameters:

ref - referenced object

isNull - if true the constructed pointer is null.

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)
          throws MemoryAccessViolationException

Description copied from class: Parameter

Writes a parameter to a function stacks.

Overrides:

push in class Pointer

Throws:

MemoryAccessViolationException

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
