Methods

edge($edge_name)

Returns a string being the name of the edge detected by Marpa::R2 in the input stream.

Pushes this edge onto a stack declared in MarpaX::Demo::StringParser.

The stack's elements are documented in "How is the parsed graph stored in RAM?" in MarpaX::Demo::StringParser.

graph($graph)

Returns the result of Marpa::R2's parse.

The result is a data structure of arrayrefs of arrayrefs nested very deeply, with the depth of nesting depending on which rules in the grammar were triggered for a given input.
