EntityQuery(T) Class

EntityQueryT Class

Breeze.sharp

An EntityQuery instance is used to query entities either from a remote datasource or from a local EntityManager. EntityQueries are immutable - this means that all EntityQuery methods that return an EntityQuery actually create a new EntityQuery. Therefore EntityQueries can be 'modified' without affecting any current instances.

Type Parameters

T

The EntityQueryT type exposes the following members.

Constructors

	Name	Description
	EntityQueryT	Constructor
	EntityQueryT(String)	Contructor for a query against a specific resource.
	EntityQueryT(EntityQueryT)	May be called by subclasses that need to add additional behavior to a query. The basic idea is to use this method to clone the query first and then add or modify properties on the cloned instance.
	EntityQueryT(Expression, IQueryable)	Initializes a new instance of the EntityQueryT class

Methods

	Name	Description
	CheckEm	(Inherited from EntityQuery.)
	Clone	For internal use only. (Overrides EntityQueryClone.)
	Equals	Determines whether the specified object is equal to the current object. (Inherited from Object.)
	Execute(EntityManager)	Executes this query, against an optionally specified EntityManager. If no EntityManager is specified then the query is run on the EntityManager specified by the EntityManager property on this instance. ( WithTQuery(TQuery, EntityManager) ) If this value is null an exception will be thrown.
	Execute(CancellationToken, EntityManager)	Executes this query, against an optionally specified EntityManager. If no EntityManager is specified then the query is run on the EntityManager specified by the EntityManager property on this instance. ( WithTQuery(TQuery, EntityManager) ) If this value is null an exception will be thrown.
	ExecuteLocally	Executes this query against the EntityManager's local cache, with an optionally specfied EntityManager. If no EntityManager is specified then the query is run on the EntityManager specified by the EntityManager property on this instance. ( WithTQuery(TQuery, EntityManager) ) If this value is null an exception will be thrown.
	Expand(String)	Returns a new query that will return related entities nested within its results. The Expand method allows you to identify related entities, via navigation property names such that a graph of entities may be retrieved with a single request. Any filtering occurs before the results are 'expanded'.
	ExpandTTarget(ExpressionFuncT, TTarget)	Returns a new query that will return related entities nested within its results. The Expand method allows you to identify related entities, via navigation property names such that a graph of entities may be retrieved with a single request. Any filtering occurs before the results are 'expanded'.
	ExpandNonGeneric	(Overrides EntityQueryExpandNonGeneric(String).)
	Finalize	Allows an object to try to free resources and perform other cleanup operations before it is reclaimed by garbage collection. (Inherited from Object.)
	From	Returns a new query with the specified resource name.
	GetEnumerator
	GetHashCode	Serves as the default hash function. (Inherited from Object.)
	GetResourcePath	For internal use. (Overrides EntityQueryGetResourcePath(MetadataStore).)
	GetType	Gets the Type of the current instance. (Inherited from Object.)
	InlineCount	Returns a query with the 'inlineCount' capability either enabled or disabled. With 'InlineCount' enabled, an additional 'InlineCount' property will be returned with the query results that will contain the number of entities that would have been returned by this query with only the 'where'/'filter' clauses applied, i.e. without any 'skip'/'take' operators applied. For local queries this clause is ignored.
	MemberwiseClone	Creates a shallow copy of the current Object. (Inherited from Object.)
	ToString	Returns a string that represents the current object. (Inherited from Object.)
	UpdateFrom	(Inherited from EntityQuery.)
	WithParameter	Returns a new query that includes a specified parameter to pass to the server.
	WithParameters	Returns a new query that includes a collection of parameters to pass to the server.

Extension Methods

	Name	Description
	AllEqualT	Overloaded. Returns true if all items in a cached collection are equal. (Defined by EnumerableFns.)
	AllEqualT, U(FuncT, U)	Overloaded. Returns true if all items in a cached collection have the same projected value. (Defined by EnumerableFns.)
	DistinctT, TResult	Returns distinct elements from a sequence by using a specified selector function to project objects to compare. (Defined by EnumerableFns.)
	ExceptT, TResult	Produces the set difference of two sequences by using a specified selector function to compare values. (Defined by EnumerableFns.)
	ForEachT(ActionT)	Overloaded. Enumerate a cached collection performing the specified action on each item. (Defined by EnumerableFns.)
	ForEachT(ActionT, Int32)	Overloaded. Enumerate an indexed collection in cache performing the specified action on each item. (Defined by EnumerableFns.)
	GetAggregateHashCode	Returns a hashcode for a collection that uses a similar algorithm to that used by the .NET Tuple class. Order matters. (Defined by EnumerableFns.)
	IndexOfT	Returns the index of the first item in the sequence matching a condition, or -1 if no match found. (Defined by EnumerableFns.)
	IntersectT, TResult	Produces the set intersection of two sequences by using a specified selector function to project objects to compare. (Defined by EnumerableFns.)
	OrderByTSource, TKey	Sorts the elements of a sequence in ascending order. (Defined by EntityQueryExtensions.)
	OrderByDescendingTSource, TKey	Sorts the elements of a sequence in descending order. (Defined by EntityQueryExtensions.)
	SelectTSource, TResult	Projects each element of a sequence into a new form. (Defined by EntityQueryExtensions.)
	SkipTSource	Bypasses a specified number of elements in a sequence and then returns the remaining elements. (Defined by EntityQueryExtensions.)
	TakeTSource	Returns a specified number of contiguous elements from the start of a sequence. (Defined by EntityQueryExtensions.)
	ThenByTSource, TKey	(Defined by EntityQueryExtensions.)
	ThenByDescendingTSource, TKey	(Defined by EntityQueryExtensions.)
	ToAggregateString	Concatenates the string version of each element in a collection using the delimiter provided. (Defined by EnumerableFns.)
	ToHashSetT	Returns a HashSetT of the specified collection. (Defined by EnumerableFns.)
	UnionT, TResult	Produces the set union of two sequences by using a specified selector function to project objects to compare. (Defined by EnumerableFns.)
	WhereTSource(ExpressionFuncTSource, Int32, Boolean)	Overloaded. Filters a sequence of values based on a predicate. (Defined by EntityQueryExtensions.)
	WhereTSource(ExpressionFuncTSource, Boolean)	Overloaded. Filters a sequence of values based on a predicate. (Defined by EntityQueryExtensions.)
