Detailed Description

template<typename T_Impl>
struct codi::TraversalLogic< T_Impl >

Traversal of CoDiPack expressions.

For a detailed explanation of the traversal structure please see Expression traversal.

Implementing classes can have members which store information required for the traversal.

Template Parameters

T_Impl

Class implementing this interface.

Member Function Documentation

leaf()

template<typename T_Impl >

template<typename Node , typename... Args>

void codi::TraversalLogic< T_Impl >::leaf ( Node const &  node, Args &&...  args  )

inline

Called for all leaf nodes in the expression.

Default: Does nothing.

link()

template<typename T_Impl >

template<size_t ChildNumber, typename Child , typename Root , typename... Args>

void codi::TraversalLogic< T_Impl >::link ( Child const &  child, Root const &  root, Args &&...  args  )

inline

Called for all links in the expression.

Implementations can call the toNode method in order to evaluate either leaf or node depending on the child.

Default: Call the child node and forward all arguments.

node()

template<typename T_Impl >

template<typename Node , typename... Args>

void codi::TraversalLogic< T_Impl >::node ( Node const &  node, Args &&...  args  )

inline

Called for each node in the expression.

Implementations can call the toLinks method in order to evaluate all links of the node.

Default: Call each link of the node and forward all arguments.
