Member Function Documentation

parse()

bool MutationOfJB::CallMacroCommandParser::parse ( const Common::String &  line, ScriptParseContext &  parseCtx, Command *&  command  )

overridevirtual

Parses the specified line and possibly returns a Command instance.

Parameters

line	Line to parse.
parseCtx	Parse context.
command	Output parameter for newly created command.

Returns

True if the line has been successfully parsed by this parser, false otherwise.

Note

You may return true and set command to nullptr. That means the line has been successfully parsed, but no command is needed.

Implements MutationOfJB::CommandParser.

transition()

void MutationOfJB::CallMacroCommandParser::transition ( ScriptParseContext &  parseCtx, Command *  oldCommand, Command *  newCommand, CommandParser *  newCommandParser  )

overridevirtual

Called when transitioning parsing between two commands.

For example, cmdParserA->transition(parseCtx, cmdA, cmdB, cmdParserB) is called after command B is done parsing to notify command A parser about the transition from command A to command B. This is useful for sequential commands, because at the time command A is being parsed, we don't have any information about command B, so we cannot set the next pointer. Transition method can be used to set the next pointer after command B is available.

Parameters

parseCtx	Parse context.
oldCommand	Old command (created by this parser).
newCommand	New command (created by newCommandParser).
newCommandParser	Command parser which created the new command.

Reimplemented from MutationOfJB::CommandParser.
