ContextStackIterator

java.lang.Object
- net.sf.saxon.trace.ContextStackIterator

All Implemented Interfaces:

java.util.Iterator
```
public class ContextStackIterator
extends java.lang.Object
implements java.util.Iterator
```
This class provides a representation of the current runtime call stack, as represented by the stack of XPathContext objects.

Constructor Summary

Constructor	Description
`ContextStackIterator(XPathContext context)`	Create an iterator over the stack of XPath dynamic context objects, starting with the top-most stackframe and working down.

Method Summary

All Methods Instance Methods Concrete Methods
Modifier and Type	Method	Description
`boolean`	`hasNext()`	Returns `true` if the iteration has more elements.
`java.lang.Object`	`next()`	Returns the next element in the iteration.
`void`	`remove()`	Removes from the underlying collection the last element returned by the iterator (optional operation).

```
public ContextStackIterator(XPathContext context)
```
    Create an iterator over the stack of XPath dynamic context objects, starting with the top-most stackframe and working down. The objects returned by this iterator will be of class ContextStackFrame
    
    Parameters:
    
    context - the current context
- Method Detail
  - hasNext
```
public boolean hasNext()
```
    Returns true if the iteration has more elements. (In other words, returns true if next would return an element rather than throwing an exception.)
    
    Specified by:
    
    hasNext in interface java.util.Iterator
    
    Returns:
    
    true if the iterator has more elements.
  - next
```
public java.lang.Object next()
```
    Returns the next element in the iteration. Calling this method repeatedly until the hasNext() method returns false will return each element in the underlying collection exactly once.
    
    Specified by:
    
    next in interface java.util.Iterator
    
    Returns:
    
    the next element in the iteration, which will always be an instance of ContextStackFrame
    
    Throws:
    
    java.util.NoSuchElementException - iteration has no more elements.
  - remove
```
public void remove()
```
    Removes from the underlying collection the last element returned by the iterator (optional operation).
    
    Specified by:
    
    remove in interface java.util.Iterator
    
    Throws:
    
    java.lang.UnsupportedOperationException - as the remove operation is not supported by this Iterator.
