Detailed Description

template<typename T, template< typename, typename > class CachingPolicy, class ThreadingPolicy>
class expression_tree::detail::default_branch< T, CachingPolicy, ThreadingPolicy >

Branch class.

This class stores an operation and two children nodes. This default implementation does no caching optimization.

Constructor & Destructor Documentation

template<typename T, template< typename, typename > class CachingPolicy, class ThreadingPolicy>

expression_tree::detail::default_branch< T, CachingPolicy, ThreadingPolicy >::default_branch	(	const typename operation< T >::t &	f,
		const node< T, CachingPolicy, ThreadingPolicy > &	l,
		const node< T, CachingPolicy, ThreadingPolicy > &	r
	)		[inline]

Constructor.

Parameters:

f	The operation to apply to this branch's children,
l	This branch's left child.
r	This branch's right child.

template<typename T, template< typename, typename > class CachingPolicy, class ThreadingPolicy>

virtual void expression_tree::detail::default_branch< T, CachingPolicy, ThreadingPolicy >::grow

(

)

[inline, virtual]

This function is called when anyone of this branch's children is modified. This default implementation does nothing when that happens.

Reimplemented in expression_tree::cache_on_assignment< T, ThreadingPolicy >::branch, and expression_tree::cache_on_evaluation< T, ThreadingPolicy >::branch.
