Overloads
| Evaluate(IEdmExpression) |
Evaluates an expression with no value context. |
| Evaluate(IEdmExpression, IEdmStructuredValue) |
Evaluates an expression in the context of a value. |
| Evaluate(IEdmExpression, IEdmStructuredValue, IEdmTypeReference) |

Evaluate(IEdmExpression)
Evaluates an expression with no value context.
public Microsoft.OData.Edm.Vocabularies.IEdmValue Evaluate (Microsoft.OData.Edm.IEdmExpression expression);member this.Evaluate : Microsoft.OData.Edm.IEdmExpression -> Microsoft.OData.Edm.Vocabularies.IEdmValuePublic Function Evaluate (expression As IEdmExpression) As IEdmValueParameters
- expression
- IEdmExpression
Expression to evaluate. The expression must not contain paths, because no context for evaluating a path is supplied.
Returns
The value that results from evaluating the expression in the context of the supplied value.
Applies to
Evaluate(IEdmExpression, IEdmStructuredValue)
Evaluates an expression in the context of a value.
public Microsoft.OData.Edm.Vocabularies.IEdmValue Evaluate (Microsoft.OData.Edm.IEdmExpression expression, Microsoft.OData.Edm.Vocabularies.IEdmStructuredValue context);member this.Evaluate : Microsoft.OData.Edm.IEdmExpression * Microsoft.OData.Edm.Vocabularies.IEdmStructuredValue -> Microsoft.OData.Edm.Vocabularies.IEdmValuePublic Function Evaluate (expression As IEdmExpression, context As IEdmStructuredValue) As IEdmValueParameters
- expression
- IEdmExpression
Expression to evaluate.
- context
- IEdmStructuredValue
Value to use as context in evaluating the expression. Cannot be null if the expression contains paths.
Returns
The value that results from evaluating the expression in the context of the supplied value.
Applies to
Evaluate(IEdmExpression, IEdmStructuredValue, IEdmTypeReference)
Evaluates an expression in the context of a value and a target type.
public Microsoft.OData.Edm.Vocabularies.IEdmValue Evaluate (Microsoft.OData.Edm.IEdmExpression expression, Microsoft.OData.Edm.Vocabularies.IEdmStructuredValue context, Microsoft.OData.Edm.IEdmTypeReference targetType);member this.Evaluate : Microsoft.OData.Edm.IEdmExpression * Microsoft.OData.Edm.Vocabularies.IEdmStructuredValue * Microsoft.OData.Edm.IEdmTypeReference -> Microsoft.OData.Edm.Vocabularies.IEdmValuePublic Function Evaluate (expression As IEdmExpression, context As IEdmStructuredValue, targetType As IEdmTypeReference) As IEdmValueParameters
- expression
- IEdmExpression
Expression to evaluate.
- context
- IEdmStructuredValue
Value to use as context in evaluating the expression. Cannot be null if the expression contains paths.
- targetType
- IEdmTypeReference
Type to which the result value is expected to conform.
Returns
The value that results from evaluating the expression in the context of the supplied value, asserted to be of the target type.
