Syntax

'Declaration
Public Class DebugInfoExpression _
    Inherits Expression
public class DebugInfoExpression : Expression

The DebugInfoExpression type exposes the following members.

Properties

  Name Description
Public property 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.)
Public property Document Gets the SymbolDocumentInfo that represents the source file.
Public property EndColumn Gets the end column of this DebugInfoExpression.
Public property EndLine Gets the end line of this DebugInfoExpression.
Public property IsClear Gets the value to indicate if the DebugInfoExpression is for clearing a sequence point.
Public property NodeType Returns the node type of this Expression. (Overrides Expression.NodeType.)
Public property StartColumn Gets the start column of this DebugInfoExpression.
Public property StartLine Gets the start line of this DebugInfoExpression.
Public property Type Gets the static type of the expression that this Expression represents. (Overrides Expression.Type.)

Methods

  Name Description
Protected method Accept Dispatches to the specific visit method for this node type. For example, MethodCallExpression calls the VisitMethodCall. (Overrides Expression.Accept(ExpressionVisitor).)
Public method Equals(Object) Determines whether the specified Object is equal to the current Object. (Inherited from Object.)
Protected method Finalize Allows an object to try to free resources and perform other cleanup operations before the Object is reclaimed by garbage collection. (Inherited from Object.)
Public method GetHashCode Serves as a hash function for a particular type. (Inherited from Object.)
Public method GetType Gets the Type of the current instance. (Inherited from Object.)
Protected method MemberwiseClone Creates a shallow copy of the current Object. (Inherited from Object.)
Public method 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.)
Public method 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.)
Public method 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.)
Public method ToString Returns a textual representation of the Expression. (Inherited from Expression.)
Protected method VisitChildren Reduces the node and then calls the visitor delegate on the reduced expression. The method throws an exception if the node is not reducible. (Inherited from Expression.)
