std::pair<unsigned int,unsigned int> coco::model::model::detect_0chain_visitor::calculate_value ( bool  eval_all  )  [inline, virtual]

This is a method which has to be defined for a cached forward evaluator.

See also:
cached_forward_evaluator_base.

Reimplemented from coco::cached_forward_evaluator_base< model::detect_0chain_visitor_st, expression_node, std::pair< unsigned int, unsigned int >, model::const_walker >.

virtual void coco::cached_forward_evaluator_base< model::detect_0chain_visitor_st , expression_node , std::pair< unsigned int, unsigned int > , model::const_walker >::cleanup ( const node_data_type __data  )  [inline, virtual, inherited]

The cleanup method is called just before calculate_value and should be used to clean up dynamically allocated data. The __data parameter contains the node data of the graph node being visited.

Definition at line 804 of file evaluator.h.

int coco::cached_forward_evaluator_base< model::detect_0chain_visitor_st , expression_node , std::pair< unsigned int, unsigned int > , model::const_walker >::collect ( const node_data_type __data,
const return_value &  __rval 
) [inline, virtual, inherited]

This method is needed by a visitor (see VGTL documentation) and is called for each normal node everytime a child node has been visited passing the return value of the child. It is translated to a call to update.

Reimplemented from coco::_evaluator_base< model::detect_0chain_visitor_st, expression_node, std::pair< unsigned int, unsigned int >,model::const_walker >.

Definition at line 750 of file evaluator.h.

int coco::model::model::detect_0chain_visitor::initialize ( const expression_node __data  )  [inline, virtual]

This is a method which has to be defined for a cached forward evaluator.

See also:
cached_forward_evaluator_base.

Reimplemented from coco::cached_forward_evaluator_base< model::detect_0chain_visitor_st, expression_node, std::pair< unsigned int, unsigned int >, model::const_walker >.

This method is needed by a visitor (see VGTL documentation) and is called right after all children of a node have been visited. It is translated into calls to calculate and cleanup.

Reimplemented from coco::_evaluator_base< model::detect_0chain_visitor_st, expression_node, std::pair< unsigned int, unsigned int >,model::const_walker >.

Definition at line 744 of file evaluator.h.

int coco::cached_forward_evaluator_base< model::detect_0chain_visitor_st , expression_node , std::pair< unsigned int, unsigned int > , model::const_walker >::preorder ( const node_data_type __data  )  [inline, virtual, inherited]

This method is needed by a visitor (see VGTL documentation) and is called right before any children of a node are visited. It checks whether the result of this node is cached and calls either retrieve_from_cache and stops the downwards walk or calls initialize.

Reimplemented from coco::cached_evaluator_base< model::detect_0chain_visitor_st, expression_node, std::pair< unsigned int, unsigned int >,model::const_walker >.

Definition at line 732 of file evaluator.h.

void coco::model::model::detect_0chain_visitor::retrieve_from_cache ( const expression_node __data  )  [inline, virtual]

This is a method which has to be defined for a cached forward evaluator.

The short_cut_to method is called whenever a short-cut is signalled during the graph walk, and the const_walker returned is the target of the short-cut.

return_value coco::cached_forward_evaluator_base< model::detect_0chain_visitor_st , expression_node , std::pair< unsigned int, unsigned int > , model::const_walker >::value (  )  [inline, virtual, inherited]

This method is needed by a visitor (see VGTL documentation) and is called right before the end of the visit of a normal node to retrieve the return value. It is translated to a call to calculate_value with parameter false.

This method is needed by a visitor (see VGTL documentation) and is called for each virtual node everytime a child node has been visited passing the return value of the child. It is translated to a call to update.

Reimplemented from coco::_evaluator_base< model::detect_0chain_visitor_st, expression_node, std::pair< unsigned int, unsigned int >,model::const_walker >.

void coco::cached_forward_evaluator_base< model::detect_0chain_visitor_st , expression_node , std::pair< unsigned int, unsigned int > , model::const_walker >::vinit (  )  [inline, inherited]

This method is needed by a visitor using recursive_short_cut_walk for traversing the graph. It is called before performing any graph walk when at a virtual node. It is translated to initialize.

This method is needed by a visitor (see VGTL documentation) and is called right before the end of the visit of a virtual node to retrieve the return value. It is translated to a call to calculate_value with parameter true.
