## Saxon.Api
Class DynamicContext

    public class DynamicContext

implements object

  The class `DynamicContext` provides information about the dynamic context of an expression

Property Summary
`XdmItem` | `ContextItem` The context item. May be null if no context item is defined
`int` | `ContextPosition` The context position (equivalent to the XPath position() function).
`int` | `ContextSize` The context size (equivalent to the XPath last() function).
`JXPathContext` | `Implementation` The underlying object in the Saxon implementation, an instance of class `net.sf.saxon.expr.XPathContext`

Property Detail

### ContextItem

    public XdmItem ContextItem {get; }

  The context item. May be null if no context item is defined

### ContextPosition

    public int ContextPosition {get; }

  The context position (equivalent to the XPath position() function).

  Calling this method throws an exception if the context item is undefined.

### ContextSize

    public int ContextSize {get; }

  The context size (equivalent to the XPath last() function).

  Calling this method throws an exception if the context item is undefined.

### Implementation

    public JXPathContext Implementation {get; }

  The underlying object in the Saxon implementation, an instance of class `net.sf.saxon.expr.XPathContext`

  This property provides access to internal methods in the Saxon engine that are not specifically exposed in the .NET API. In general these methods should be considered to be less stable than the classes in the Saxon.Api namespace.

  The internal methods follow Java naming conventions rather than .NET conventions.

  Information about the returned object (and the objects it provides access to) is included in the Saxon JavaDoc docmentation, available online.
