Detailed Description

This is a visitor that converts a parse tree into a list of transitions that a shift-reduce parser would have to take in order to generate it.

The transitions are built up via side-effect on the visitor, so its visiting functions return void, but the visitor itself has a function to obtain the list of transitions after visiting has been completed.

Member Function Documentation

void meta::parser::transition_finder::operator() ( const leaf_node &  )

overridevirtual

Returns

the result of running the visitor on the supplied leaf node

Implements meta::parser::const_visitor< void >.

void meta::parser::transition_finder::operator() ( const internal_node &  )

overridevirtual

Returns

the result of running the visitor on the supplied internal node

Implements meta::parser::const_visitor< void >.

std::vector< transition > meta::parser::transition_finder::transitions

(

)

Extracts the transitions out of the visitor.

This moves the transition vector from the visitor.

Returns

the transtions found when running the visitor on the tree
