A5.u.jsoncompress Method
Syntax
A5.u.json.compress(object,map)
Arguments
- objectobjectarray
The object or array to compress.
- mapobject
The object that will be dynamically filled in with the property name map.
Returns
- compressedObjectobject
The compressed version of the passed in object.
Description
Compress an object for storage purposes.
Discussion
This method will take an arbitrary object and convert all property names to a short name (such as "a"). The passed in map object will be populated with the long names to match the short names generated, to be used by A5.u.json.expand to return the original uncompressed object. This is useful for compressing large, repetitive data.
Example
var map = {};
var obj = [{name: 'Bob', age: 54},{name: 'Fred', age: 32}];
var cObj = A5.u.json.compress(obj,map);
// cObj = [{a: 'Bob', b: 54},{a: 'Fred', b: 32}];
// map = {a: 'name', b: 'age'};
