Defined in header <cparse/Parser.hh>

virtual std::string getGrammarName() const noexcept = 0;

Returns a short identifier for the grammar. Used by writeTraceMessage() and suitable for embedding in log lines.

Parameters

None.

Return value

A short string identifying the grammar. Anything that makes sense in logs — "fson", "csv-lite", "umtsm-input".

Exceptions

noexcept. Implementations should not throw.

Notes

This is one of only two = 0 methods on Parser; the other is start(). Both must be overridden by concrete grammars.

Example

class CsvParser : public fedem::parser::Parser
{
public:
    std::string getGrammarName() const noexcept override { return "csv"; }
    // ...
};
