◆ Clone()

ParserTokenReader * mu::ParserTokenReader::Clone ( ParserBase * a_pParent ) const

Create an error containing the parse error position.

This function will create an Parser Exception object containing the error text and its position.

Parameters

a_iErrc	[in] The error code of type EErrorCodes.
a_iPos	[in] The position where the error was detected.
a_strTok	[in] The token string representation associated with the error.

Check Expression for the presence of a binary operator token.

Userdefined binary operator "++" gives inconsistent parsing result for the equations "a++b" and "a ++ b" if alphabetic characters are allowed in operator tokens. To avoid this this function checks specifically for operator tokens.
