Member Data Documentation

string ScannerDfaSpec::className

The name of the generated scanner class. Definition at line 92 of file scanner_dfa_spec.hh.

CodeChunk ScannerDfaSpec::preambleCode

The user code to be inserted before the scanner's class declaration. Definition at line 97 of file scanner_dfa_spec.hh.

vector< CodeChunk > ScannerDfaSpec::userCode

The user code that will be lumped inside the scanner's class. If multiple blocks or code are found inside the lexical section, they are concatenated into one big chunk of code stored into this string. Definition at line 104 of file scanner_dfa_spec.hh.

CodeChunk ScannerDfaSpec::inheritance

This string contains the inheritance provided by the user for the scanner class. Definition at line 110 of file scanner_dfa_spec.hh.

vector< BasicDfaSpec *> ScannerDfaSpec::states

This holds the list with the DFAs for each lexical state. Definition at line 115 of file scanner_dfa_spec.hh.
