h4 What is <code>ref</code>?
|
|
p
|
|
code ref
|
|
| is a native addon for
|
|
a(href="http://nodejs.org") Node.js
|
|
| that aids in doing C programming in JavaScript, by extending
|
|
| the built-in
|
|
a(href="http://nodejs.org/api/buffer.html")
|
|
code Buffer
|
|
| class
|
|
| with some fancy additions like:
|
|
ul
|
|
li Getting the memory address of a Buffer
|
|
li Checking the endianness of the processor
|
|
li Checking if a Buffer represents the NULL pointer
|
|
li Reading and writing "pointers" with Buffers
|
|
li Reading and writing C Strings (NULL-terminated)
|
|
li Reading and writing JavaScript Object references
|
|
li Reading and writing
|
|
strong int64_t
|
|
| and
|
|
strong uint64_t
|
|
| values
|
|
li A "type" convention to define the contents of a Buffer
|
|
p
|
|
| There is indeed a lot of
|
|
em meat
|
|
| to
|
|
code ref
|
|
| , but it all fits together in one way or another in the end.
|
|
br
|
|
| For simplicity,
|
|
code ref
|
|
| 's API can be broken down into 3 sections:
|
|
a.nav.columns.five(href='#exports')
|
|
h4 ref <code>exports</code>
|
|
p
|
|
| All the static versions of
|
|
code ref
|
|
| 's functions and default "types" available on the exports returned from
|
|
code require('ref')
|
|
| .
|
|
a.nav.columns.five(href='#types')
|
|
h4 <em>"type"</em> system
|
|
p
|
|
| The
|
|
em "type"
|
|
| system allows you to define a "type" on any Buffer instance, and then
|
|
| use generic
|
|
code ref()
|
|
| and
|
|
code deref()
|
|
| functions to reference and dereference values.
|

h4 <code>Buffer</code> extensions
|
|
p
|
|
code Buffer.prototype
|
|
| gets extended with some convenience functions. These all just mirror
|
|
| their static counterpart, using the Buffer's
|
|
code this
|
|
| variable as the
|
|
code buffer
|
|
| variable.

p
|
|
| A "type" in
|
|
code ref
|
|
| is simply an plain 'ol JavaScript Object, with a set
|
|
| of expected properties attached that implement the logic for getting
|
|
| & setting values on a given
|
|
code Buffer
|
|
| instance.
|
|
p
|
|
| To attach a "type" to a Buffer instance, you simply attach the "type"
|
|
| object to the Buffer's <code>type</code> property.
|
|
code ref
|
|
| comes with a set of commonly used types which are described in this
|
|
| section.
|
|
h4 Creating your own "type"
|
|
p
|
|
| It's trivial to create your own "type" that reads and writes your
|
|
| own custom datatype/class to and from Buffer instances using
|
|
code ref
|
|
| 's unified API.
|
|
br
|
|
| To create your own "type", simply create a JavaScript Object with
|
|
| the following properties defined:
|
|
table
|
|
tr
|
|
th Name
|
|
th Data Type
|
|
th Description
|
|
tr
|
|
td: code size
|
|
td: code Number
|
|
td The size in bytes required to hold this datatype.
|
|
tr
|
|
td: code indirection
|
|
td: code Number
|
|
td
|
|
| The current level of indirection of the buffer. When defining
|
|
| your own "types", just set this value to <code>1</code>.
|
|
tr
|
|
td: code get
|
|
td: code Function
|
|
td
|
|
| The function to invoke when
|
|
a(href="#exports-get")
|
|
code ref.get()
|
|
| is invoked on a buffer of this type.
|
|
tr
|
|
td: code set
|
|
td: code Function
|
|
td
|
|
| The function to invoke when
|
|
a(href="#exports-set")
|
|
code ref.set()
|
|
| is invoked on a buffer of this type.
|
|
tr
|
|
td: code name
|
|
td: code String
|
|
td
|
|
em (Optional)
|
|
| The name to use during debugging for this datatype.
|
|
tr
|
|
td: code alignment
|
|
td: code Number
|
|
td
|
|
em (Optional)
|
|
| The alignment of this datatype when placed inside a struct.
|
|
| Defaults to the type's
|
|
code size
|
|
| .
|
|
h4 The built-in "types"
|
|
p
|
|
| Here is the list of
|
|
code ref
|
|
| 's built-in "type" Objects. All these built-in "types" can be found
|
|
| on the
|
|
code ref.types
|
|
| export Object. All the built-in types use "native endianness" when
|
|
| multi-byte datatypes are involved.
