Module: state-store

Module: state-store

The state store can keep track of any JSON-style data object for other modules to access and use.

The state store is used as centralized data storage for all modules, especially when concerning data that is shared among 2 or more modules. When individual modules need to update specific data, modifications through the state store ensure that other modules that need to be aware of the latest available data can do so without specific input from the module changing it.

The state store can store any number of states, as defined by a data string. See module:event-store#event:ModifyState. It is able to associate any data object with that particular state, although it is optimized to store key-value Objects.

Fires:
Listens to Events:
Example
var StateStore = require('state-store.js');

// a generic Viewer constructor
function Viewer(opts) {
    // other modules will expect this to be present
    this.stateStore = StateStore(this);
}

(require("state-store"))(viewer)

Creates and initializes the state store.

Parameters:
Name Type Description
viewer Core

The core viewer to which the module will attach.
