Model of relationships between streams based on properties in both streams that are specified as equal in a filter expression.

The following tables list the members exposed by the QueryGraph type.

Public Methods

  NameDescription
Add
Add properties for 2 streams that are equal.

Equals
Determines whether the specified Object is equal to the current Object.
(Inherited from Object.)
static memberFillEquivalentNav
Fill in equivalent key properties (navigation entries) on all streams. For example, if a=b and b=c then add a=c. The method adds new equalivalent key properties until no additional entries to be added are found, ie. several passes can be made.

GetHashCode
Serves as a hash function for a particular type. GetHashCode() is suitable for use in hashing algorithms and data structures like a hash table.
(Inherited from Object.)
GetIndexProperties
Returns index properties.

GetKeyProperties
Returns key properties.

GetNavigableStreams
Returns set of streams that the given stream is navigable to.

GetType
Gets the Type of the current instance.
(Inherited from Object.)
IsNavigable
Returns true if there is a relationship between streams via equal properties.

ToString
Returns a String that represents the current Object.
(Overrides .ToString().)

Protected Methods

  NameDescription
Finalize
Allows an Object to attempt to free resources and perform other cleanup operations before the Object is reclaimed by garbage collection.
(Inherited from Object.)
MemberwiseClone
Creates a shallow copy of the current Object.
(Inherited from Object.)
