Class State

Maintain state for a collection of items. Individual properties are stored in hash tables. This is instead of having state objects for each item in the collection. For large collections, especially changing ones, this approach may perform better.

name <string> identifier for this attribute
o <object> hash of attributes
Returns: void

get

get ( name , key )
For a given item, gets an attribute. If key is not supplied, a disposable object with all attributes is returned. Use of the latter option makes sense when working with single items, but not if object explosion might cause gc problems.

remove

void remove ( name , o )
Remove entire item, or optionally specified fields
Parameters:
name <string> name of attribute
o <string|object|array> single key or collection of keys to delete
