Namespace:  System.Data.Services
Assembly:  System.Data.Services (in System.Data.Services.dll)

public class ExpandSegment

The ExpandSegment type exposes the following members.

Public methodExpandSegmentInitializes an ExpandSegment object with the specified property name and a filtering expression, possibly null.

Public propertyExpandedPropertyGets the property to be expanded.
Public propertyFilterThe filter option in the query to which the expand segment applies.
Public propertyHasFilterA Boolean value that indicates whether the expand statement is used with a filter expression.
Public propertyMaxResultsExpectedGets the maximum number of results expected.
Public propertyNameThe name of the property to be expanded.

Public methodEquals(Object)Determines whether the specified Object is equal to the current Object. (Inherited from Object.)
Protected methodFinalizeAllows an object to try to free resources and perform other cleanup operations before it is reclaimed by garbage collection. (Inherited from Object.)
Public methodGetHashCodeServes as a hash function for a particular type. (Inherited from Object.)
Public methodGetTypeGets the Type of the current instance. (Inherited from Object.)
Protected methodMemberwiseCloneCreates a shallow copy of the current Object. (Inherited from Object.)
Public methodStatic memberPathHasFilterA Boolean value that indicates whether the path includes a filter option on target data.
Public methodToStringReturns a string that represents the current object. (Inherited from Object.)

An $expandclause indicates that each $expanditem should be fully expanded. For example, the value OrderLines.Product.Image with $expand causes OrderLines, the Product of each element in OrderLines, and the Image of the Product of each element in OrderLines to be expanded.

The left-most property in an $expand clause must be a property on the entity type within the entity set identified by the last path segment in the request URI.

Redundant expand clause rules are acceptable and ignored.

The following URI expands the OrderLines associated with each Order returned by the query.
