RuntimeVariablesExpression RuntimeVariablesExpression RuntimeVariablesExpression RuntimeVariablesExpression Class

Definition

An expression that provides runtime read/write permission for variables.

Remarks

This type is necessary for implementing "eval" in dynamic languages. It evaluates to an instance of IList<T> at run time.

Properties

CanReduce CanReduce CanReduce CanReduce

Indicates that the node can be reduced to a simpler node. If this returns true, Reduce() can be called to produce the reduced form.

(Inherited from Expression)
NodeType NodeType NodeType NodeType

Returns the node type of this Expression. Extension nodes should return Extension when overriding this method.

Type Type Type Type

Gets the static type of the expression that this Expression represents.

Variables Variables Variables Variables

The variables or parameters to which to provide runtime access.

Methods

Accept(ExpressionVisitor) Accept(ExpressionVisitor) Accept(ExpressionVisitor) Accept(ExpressionVisitor)

Dispatches to the specific visit method for this node type. For example, MethodCallExpression calls the VisitMethodCall(MethodCallExpression).

(Inherited from Expression)
Equals(Object) Equals(Object) Equals(Object) Equals(Object)

Determines whether the specified object is equal to the current object.

(Inherited from Object)
GetHashCode() GetHashCode() GetHashCode() GetHashCode()

Serves as the default hash function.

(Inherited from Object)
GetType() GetType() GetType() GetType()

Gets the Type of the current instance.

(Inherited from Object)
MemberwiseClone() MemberwiseClone() MemberwiseClone() MemberwiseClone()

Creates a shallow copy of the current Object.

(Inherited from Object)
Reduce() Reduce() Reduce() Reduce()

Reduces this node to a simpler expression. If CanReduce returns true, this should return a valid expression. This method can return another node which itself must be reduced.

(Inherited from Expression)
ReduceAndCheck() ReduceAndCheck() ReduceAndCheck() ReduceAndCheck()

Reduces this node to a simpler expression. If CanReduce returns true, this should return a valid expression. This method can return another node which itself must be reduced.

(Inherited from Expression)
ReduceExtensions() ReduceExtensions() ReduceExtensions() ReduceExtensions()

Reduces the expression to a known node type (that is not an Extension node) or just returns the expression if it is already a known type.

(Inherited from Expression)
ToString() ToString() ToString() ToString()

Returns a textual representation of the Expression.

(Inherited from Expression)
Update(IEnumerable<ParameterExpression>) Update(IEnumerable<ParameterExpression>) Update(IEnumerable<ParameterExpression>) Update(IEnumerable<ParameterExpression>)

Creates a new expression that is like this one, but using the supplied children. If all of the children are the same, it will return this expression.

VisitChildren(ExpressionVisitor) VisitChildren(ExpressionVisitor) VisitChildren(ExpressionVisitor) VisitChildren(ExpressionVisitor)

Reduces the node and then calls the visitor delegate on the reduced expression. The method throws an exception if the node is not reducible.
