Package net.sf.saxon.expr.instruct

## Class ApplyTemplates.ApplyTemplatesPackage

- java.lang.Object
- - net.sf.saxon.expr.instruct.ApplyTemplates.ApplyTemplatesPackage

- All Implemented Interfaces:
    `TailCall`
  Enclosing class:
    ApplyTemplates

      protected static class ApplyTemplates.ApplyTemplatesPackage
      extends java.lang.Object
      implements TailCall

  An ApplyTemplatesPackage is an object that encapsulates the sequence of nodes to be processed, the mode, the parameters to be supplied, and the execution context. This object can be returned as a tail call, so that the actual call is made from a lower point on the stack, allowing a tail-recursive template to execute in a finite stack size

    - #### processLeavingTail

          public TailCall processLeavingTail()
                                      throws XPathException

      Description copied from interface: `TailCall`
      Process this TailCall (that is, executed the template call that is packaged in this object). This may return a further TailCall, which should also be processed: this is the mechanism by which a nested set of recursive calls is converted into an iteration.
      Specified by:
        `processLeavingTail` in interface `TailCall`
      Returns:
        a further TailCall, if the recursion continues, or null, indicating that the recursion has terminated.
      Throws:
        `XPathException` - if any error occurs processing the tail call
