// Stone PHP SafeCrypt Compressors
|
|
// -------------------------------
|
|
//
|
|
// To add a new compressor, create a new member in the $compressors array. Its key should be
|
|
// the string by which the user calls the compressor. Its value should be an array with two
|
|
// members, 'encode' and 'decode', each themselves arrays. Each of the compressor entries
|
|
// should also have a 'desc' member, to give a descriptive name to each compression method,
|
|
// in case someone wants to build something larger on this library and needs tooltip or
|
|
// statusbar descriptive text.
|
|
//
|
|
// Each encode and decode must have the 'fname' member, which contains the name of the encoding
|
|
// or decoding function as appropriate.
|
|
//
|
|
// Each may have the 'args' member, which is a list of arguments that will be passed to the
|
|
// function, in order. If either array has the 'args' member, it must therefore also have the
|
|
// 'data_arg' member, which is the index of the argument to override with the actual data to be
|
|
// compressed or uncompressed.
|
|
//
|
|
// If the array does not have the 'args' and 'data_args' members, the function will be assumed
|
|
// to take only one value, the data for compression or decompression.
