Pointer class

Pointer to arbitrary memory location.

Subclasses: Memory

Initialization

static function create(lo: Integer, hi: Integer): Pointer

Creates a new pointer with given address.

static function from_shared_array(shared_array): Pointer

Creates a new pointer with address used by the shared array.

Manipulation

function get_value(): Integer, Integer

Returns the address of this pointer as two results (low and high part).

function with_offset(offset: Integer): Pointer

Returns a new pointer with given offset.

function get_view(off: Integer, len: Integer, elem_size: Integer): Integer[]

Creates a view into memory as a shared array.

Memory access

function set_byte(offset: Integer, value: Integer)
function set_short(offset: Integer, value: Integer)
function set_int(offset: Integer, value: Integer)
function set_long(offset: Integer, value_lo: Integer, value_hi: Integer)
function set_nlong(offset: Integer, value_lo: Integer, value_hi: Integer)
function set_float(offset: Integer, value: Float)
function set_double(offset: Integer, value_lo: Integer, value_hi: Integer)
function set_pointer(offset: Integer, value: Pointer)


Sets memory location to given value. Offset is in bytes.

function get_byte(offset: Integer): Integer

function get_nlong(offset: Integer): Integer, Integer
function get_float(offset: Integer): Float
function get_double(offset: Integer): Integer, Integer
function get_pointer(offset: Integer): Pointer


Gets value from memory location. Offset is in bytes.

function set_bytes(offset: Integer, arr: Byte[])
function set_bytes(offset: Integer, arr: Byte[], off: Integer, len: Integer)


Copies bytes from given array to given memory location.

function get_bytes(offset: Integer, arr: Byte[])
function get_bytes(offset: Integer, arr: Byte[], off: Integer, len: Integer)


Copies bytes from given memory location to given array.

Utility functions

function find_int(offset: Integer, end_offset: Integer, value: Integer): Integer


Searches for value, returning an index (-1 if not found).

function get_string_length(offset: Integer): Integer

Returns length of the zero-terminated string.

function get_string(offset: Integer): String

Returns string from given memory location.

function get_string_utf8(offset: Integer): String

Returns UTF-8 string from given memory location.

function set_string(offset: Integer, value: String)

Sets string at given memory location.

function set_string_utf8(offset: Integer, value: String)

Sets UTF-8 string at given memory location.
