Instances of the EntityManager contain and manage collections of entities, either retrieved from a backend datastore or created on the client.
@class EntityManager
 
At its most basic an EntityManager can be constructed with just a service name
@example
var entityManager = new EntityManager( "breeze/NorthwindIBModel");
This is the same as calling it with the following configuration object
@example
var entityManager = new EntityManager( {serviceName: "breeze/NorthwindIBModel" });
Usually however, configuration objects will contain more than just the 'serviceName';
@example
var metadataStore = new MetadataStore();
var entityManager = new EntityManager( {
serviceName: "breeze/NorthwindIBModel",
metadataStore: metadataStore
});
or
@example
return new QueryOptions({
mergeStrategy: obj,
fetchStrategy: this.fetchStrategy
});
var queryOptions = new QueryOptions({
mergeStrategy: MergeStrategy.OverwriteChanges,
fetchStrategy: FetchStrategy.FromServer
});
var validationOptions = new ValidationOptions({
validateOnAttach: true,
validateOnSave: true,
validateOnQuery: false
});
var entityManager = new EntityManager({
serviceName: "breeze/NorthwindIBModel",
queryOptions: queryOptions,
validationOptions: validationOptions
});
@method <ctor> EntityManager
@param [config] {Object|String} Configuration settings or a service name.
@param [config.serviceName] {String}
@param [config.dataService] {DataService} An entire DataService (instead of just the serviceName above).
@param [config.metadataStore=MetadataStore.defaultInstance] {MetadataStore}
@param [config.queryOptions] {QueryOptions}
@param [config.saveOptions] {SaveOptions}
@param [config.validationOptions=ValidationOptions.defaultInstance] {ValidationOptions}
@param [config.keyGeneratorCtor] {Function}
