This is an abstract API that data provider implementations conform to. This file defines methods signatures and intentionally leaves all the methods unimplemented. For more information on the , please visit: http://dojotoolkit.org/reference-guide/dojo/store.html Every method and property is optional, and is only needed if the functionality it provides is required. Every method may return a promise for the specified return value if the execution of the operation is asynchronous (except for query() which already defines an async return value).
Defined by: dojo/store/api/Store
If the store has a single primary key, this indicates the property to use as the identity property. The values of this property should be unique.
queryEngine
Defined by: dojo/store/api/Store
If the store can be queried locally (on the client side in JS), this defines the query engine to use for querying the data store. This takes a query and query options and returns a function that can execute the provided query on a JavaScript array. The queryEngine may be replace to provide more sophisticated querying capabilities. For example:
var query = store.queryEngine({foo:"bar"}, {count:10});
query(someArray) -> filtered array
The returned query function may have a "matches" property that can be
used to determine if an object matches the query. For example:
query.matches({id:"some-object", foo:"bar"}) -> true
query.matches({id:"some-object", foo:"something else"}) -> false
