SyntaxThe LetPattern type exposes the following members.
Constructors| Name | Description | |
|---|---|---|
 | LetPattern |
Creates a new LET Pattern.
|
Properties| Name | Description | |
|---|---|---|
 | AssignExpression |
Gets the Expression that is used to generate values to be assigned.
|
| FixedVariables |
Returns an empty enumeration as any evaluation error will result in an unbound value so we can't guarantee any variables are bound.
(Overrides BaseTriplePatternFixedVariables.) |
| FloatingVariables |
Returns the variable being assigned to as any evaluation error will result in an unbound value so we can't guarantee it is bound.
(Overrides BaseTriplePatternFloatingVariables.) |
| HasNoBlankVariables |
Returns true as a LET can never contain Blank Nodes.
(Overrides BaseTriplePatternHasNoBlankVariables.) |
| IsAcceptAll |
Returns that this is not an accept all since it is a LET assignment.
(Overrides BaseTriplePatternIsAcceptAll.) |
| PatternType |
Gets the Pattern Type.
(Overrides BaseTriplePatternPatternType.) |
| UsesDefaultDataset |
Gets whether the Pattern uses the Default Dataset.
(Overrides BaseTriplePatternUsesDefaultDataset.) |
| VariableName |
Gets the Name of the Variable to which values will be assigned.
|
| Variables |
Gets the List of Variables used in the Pattern.
(Inherited from BaseTriplePattern.) |
Methods| Name | Description | |
|---|---|---|
| CompareTo(IAssignmentPattern) |
Compares this Let to another Let.
|
| CompareTo(ITriplePattern) |
Compares a Triple Pattern to another Triple Pattern.
(Inherited from BaseTriplePattern.) |
| CompareTo(LetPattern) |
Compares this Let to another Let.
|
| Equals | Determines whether the specified object is equal to the current object. (Inherited from Object.) |
| Evaluate |
Evaluates a LET assignment in the given Evaluation Context.
(Overrides BaseTriplePatternEvaluate(SparqlEvaluationContext).) |
 | 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.) |
| MemberwiseClone | Creates a shallow copy of the current Object. (Inherited from Object.) |
