SyntaxThe GraphPattern type exposes the following members.
Properties| Name | Description | |
|---|---|---|
 | ChildGraphPatterns |
Gets the Child Graph Patterns of this Pattern.
|
| Filter |
Gets/Sets the FILTER that applies to this Graph Pattern.
|
| GraphSpecifier |
Gets/Sets the Graph Specifier that applies to this Graph Pattern.
|
| HasChildGraphPatterns |
Checks whether this Pattern has any Child Graph Patterns.
|
| HasInlineData |
Gets whether this Graph Pattern contains an Inline Data block (VALUES clause).
|
| HasModifier |
Determines whether the Graph Pattern has any kind of Modifier (GRAPH, MINUS, OPTIONAL etc) applied.
|
| InlineData |
Gets the inline data (VALUES block if any).
|
| IsEmpty |
Gets whether this is an empty Graph Pattern.
|
| IsExists |
Gets/Sets whether the Graph Pattern is an EXISTS clause.
|
| IsFiltered |
Gets/Sets whether the Graph Pattern is Filtered.
|
| IsGraph |
Gets/Sets whether the Graph Pattern operates on a specific Graph.
|
| IsMinus |
Gets/Sets whether the Graph Pattern is a MINUS clause.
|
| IsNotExists |
Gets/Sets whether the Graph Pattern is a NOT EXISTS clause.
|
| IsOptimised |
Gets whether Optimisation has been applied to this query.
|
| IsOptional |
Gets/Sets whether the Graph Pattern is Optional.
|
| IsService |
Gets/Sets whether the Graph Pattern is a SERVICE clause.
|
| IsSilent |
Gets whether Evaluation Errors in this Graph Pattern are suppressed (currently only valid with SERVICE).
|
| IsSubQuery |
Gets whether this Graph Pattern is a Sub-query which can be simplified.
|
| IsUnion |
Gets/Sets whether the Graph Pattern is a Union of its Child Graph Patterns.
|
| TriplePatterns |
Gets the Triple Patterns in this Pattern.
|
| UnplacedAssignments |
Gets the enumeration of LET assignments that are in this Graph Pattern which will be placed appropriately later.
|
| UnplacedFilters |
Gets the enumeration of Filters that apply to this Graph Pattern which will have yet to be placed within the Graph Pattern.
|
| UsesDefaultDataset |
Gets whether the Graph Pattern uses the Default Dataset.
|
| Variables |
Gets the Variables used in the Pattern.
|
Methods| Name | Description | |
|---|---|---|
 | Equals | Determines whether the specified object is equal to the current object. (Inherited from Object.) |
 | Finalize | Allows an object to try to free resources and perform other cleanup operations before it is reclaimed by garbage collection. (Inherited from Object.) |
| GetHashCode | Serves as the default hash function. (Inherited from Object.) |
| GetType | Gets the Type of the current instance. (Inherited from Object.) |
| InsertAssignment |
Inserts an Assignment at a given position.
|
| InsertFilter |
Inserts a Filter at a given position.
|
| MemberwiseClone | Creates a shallow copy of the current Object. (Inherited from Object.) |
| Optimise() |
Optimises the Graph Pattern using the current global optimiser.
|
| Optimise(IQueryOptimiser) |
Optimises the Graph Pattern using the given optimiser.
|
| Optimise(IQueryOptimiser, IEnumerable<String>) |
Optimises the Graph Pattern using the given optimiser and with the given variables.
|
| SwapTriplePatterns |
Swaps the position of the two given Triple Patterns.
|
| ToAlgebra |
Gets the Algebra representation of the Graph Pattern.
|
| ToString |
