Detailed Description

template<typename T, template< typename, typename > class CachingPolicy = no_caching, class ThreadingPolicy = sequential>
class expression_tree::node< T, CachingPolicy, ThreadingPolicy >

The tree's node class.

This class stores a pointer to its implementation. The implementation node's type is derived at runtime when it is assigned to.

Constructor & Destructor Documentation

template<typename T, template< typename, typename > class CachingPolicy = no_caching, class ThreadingPolicy = sequential>

expression_tree::node< T, CachingPolicy, ThreadingPolicy >::node ( node< T, CachingPolicy, ThreadingPolicy > *  parent = 0 )

inline

Default constructor.

Parameters

parent

Pointer to this node's parent.

Member Function Documentation

template<typename T, template< typename, typename > class CachingPolicy = no_caching, class ThreadingPolicy = sequential>

void expression_tree::node< T, CachingPolicy, ThreadingPolicy >::grow ( )

inline

Called when this node is assigned to.

Recursively notifies parent nodes of the growth that happened.

template<typename T, template< typename, typename > class CachingPolicy = no_caching, class ThreadingPolicy = sequential>

node<T, CachingPolicy, ThreadingPolicy>& expression_tree::node< T, CachingPolicy, ThreadingPolicy >::left ( )

inline

This node's left child.

Note that if this node is a leaf node, behavior is undefined.

template<typename T, template< typename, typename > class CachingPolicy = no_caching, class ThreadingPolicy = sequential>

node<T, CachingPolicy, ThreadingPolicy>& expression_tree::node< T, CachingPolicy, ThreadingPolicy >::operator= ( const T &  t )

inline

Assign a value to this node.

The assignment of a T designates this node as a leaf node. A leaf can still be changed to a branch by assigning an operation to it.

template<typename T, template< typename, typename > class CachingPolicy = no_caching, class ThreadingPolicy = sequential>

node<T, CachingPolicy, ThreadingPolicy>& expression_tree::node< T, CachingPolicy, ThreadingPolicy >::operator= ( const T *  t )

inline

Assign a pointer to this node.

The assignment of a T* designates this node as a leaf node. A leaf can still be changed to a branch by assigning an operation to it.

template<typename T, template< typename, typename > class CachingPolicy = no_caching, class ThreadingPolicy = sequential>

node<T, CachingPolicy, ThreadingPolicy>& expression_tree::node< T, CachingPolicy, ThreadingPolicy >::operator= ( const typename detail::operation< T >::t &  f )

inline

Assign an operation to this node.

The assignment of an operation designates this node as a branch. A branch can still be changed to a leaf by assigning data to it.

template<typename T, template< typename, typename > class CachingPolicy = no_caching, class ThreadingPolicy = sequential>

node<T, CachingPolicy, ThreadingPolicy>& expression_tree::node< T, CachingPolicy, ThreadingPolicy >::right ( )

inline

This node's right child.

Note that if this node is a leaf node, behavior is undefined.
