Bice, a tiny module that offers a fast way to swap arbitrary length sequences of bytes within a Buffer, using only the Buffer itself and the bitwise XOR operator.
$ npm install bice [-g]
require returns an helper hash/obj.
var Bice = ;
to run all test files, install devDependecies:
$ cd bice/# install or update devDependecies$ npm install --dev# run tests$ npm test
to execute a single test file simply do:
$ node test/file-name.js
Arguments within [ ] are optional.
/** Swap 2 sequences in a Buffer, swapping 1 byte at the time.* It returns true if swapping was successfull, false otherwise.** NOTE:* - sequences shouldn't overlap.* - sequences shouldn't overflow Buffer length.* - sequence 1 starts from pos1 and ends to pos1 + bytes - 1.* - sequence 2 starts from pos2 and ends to pos2 + bytes - 1.* - pos1 could be > than pos2, the order of indexes doesn't matter.*/Bice# : Boolean/** Reverse an entire Buffer or a part of it, swapping 1 byte at the time.* It returns true if reversing was successfull, false otherwise.*/Bice#reverse : function ( Buffer buffer [, Number pos [, Number bytes ] ] ) : Boolean/** Compares values from 2 buffers.* Optionally, it accepts the number of bytes to read; if it is not specified,* it compares a number of bytes equals to the length of the smaller Buffer.** It returns:** - 0 when b1 === b2* - +1 when b1 > b2* - -1 when b1 < b2* - null otherwise (read index overflow, 0-length Buffers, ..)**/Bice#compare : function ( Buffer b1, Number p1, Buffer b2, Number p2 [, Number bytes ] ) : Number
