Syntax

public sealed class PathEvaluationContext

Properties

CurrentObject

Gets or sets the current object (the result of the previous traversal). This will be null if IsRoot is true.

Declaration

public object CurrentObject { get; }

Property Value

Type	Description
System.Object	The current object.

ExpressionContext

Gets the expression context associated with this evaluation context.

Declaration

public ExpressionContext ExpressionContext { get; }

Property Value

Type	Description
ExpressionContext	The expression context.

IsRoot

Gets a value indicating whether this PathEvaluationContext is the root context in a traversal. If this is true then the CurrentObject will be null.

Declaration

public bool IsRoot { get; }

Property Value

Type	Description
System.Boolean	true if this is the root context; otherwise, false.

Methods

CreateChild(Object)

Creates a child context, based upon the current instance but with a different CurrentObject.

Declaration

public PathEvaluationContext CreateChild(object currentObject)

Parameters

Type	Name	Description
System.Object	currentObject	The new 'current' object for the created context.

Returns

Type	Description
PathEvaluationContext	The child context.

CreateRoot(ExpressionContext)

Creates a new root context instance.

Declaration

public static PathEvaluationContext CreateRoot(ExpressionContext expressionContext)

Parameters

Type	Name	Description
ExpressionContext	expressionContext	The expression context.

Returns

Type	Description
PathEvaluationContext	The root path evaluation context.
