Method Detail

getPointer

public Pointer getPointer(long offset)

Description copied from class: Pointer

Reads an Pointer value at the given offset.

Specified by:

getPointer in class Pointer

Parameters:

offset - the offset from the start of the memory this Pointer represents at which the value will be read.

Returns:

the Pointer value read from memory.

public Pointer getPointer(long offset,
                          long size)

Description copied from class: Pointer

Reads an Pointer value at the given offset.

Specified by:

getPointer in class Pointer

Parameters:

offset - the offset from the start of the memory this Pointer represents at which the value will be read.

size - the maximum size of the memory location the returned Pointer represents.

Returns:

the Pointer value read from memory.

putPointer

public void putPointer(long offset,
                       Pointer value)

Description copied from class: Pointer

Writes a Pointer value at the given offset.

Specified by:

putPointer in class Pointer

Parameters:

offset - The offset from the start of the memory this Pointer represents at which the value will be written.

value - the Pointer value to be written to memory.
