Member Typedef Documentation

A define.

The dictionary.

Error codes.

LSBOOL LSE_CALL lsg::CPreProc::EvalNode	(	LSUINT32	_ui32Index,
		LSINT64 &	_i64Return,
		const LSG_MACROS &	_mMacros
	)		const `[protected]`

Process a single node and return the result of that node.

Parameters:

_ui32Index	The index of the node to process.
_i64Return	Holds the return value of the node.
_mMacros	The macros.

CPreProcContainer& LSE_CALL lsg::CPreProc::GetContainer ( )

Get the container.

LSBOOL LSE_CALL lsg::CPreProc::GetResult	(	const LSG_MACROS &	_mMacros,
		LSBOOL &	_bRet
	)		const

Evaluate the parsed expression with the given macro dictionary.

Parameters:

_mMacros	The macros.
_bRet	Holds the result of the expression.

LSG_ERRORS LSE_CALL lsg::CPreProc::Parse ( const CString & _sExp )

Parse an expression, returning an error code.

Parameters:

_sExp The expression to parse.

Returns:: Returns an error code depending on the result of the expression. LSG_E_ERROR is returned if the expression is bad. LSG_E_FAILURE indicates the expression is valid, but evaluates to 0. LSG_E_SUCCESS indicates that the expression is valid and evaluates to 1.

The container for holding the parsed data.
