FX::FXExpression::FXExpression ( )

Construct empty expression object.

FX::FXExpression::FXExpression ( const FXExpression & orig )

Copy expression object.

FX::FXExpression::FXExpression	(	const FXchar *	expression,
		const FXchar *	variables = `NULL`,
		FXExpressionError *	error = `NULL`
	)

Compile expression; if error is not NULL, error code is returned.

FX::FXExpression::FXExpression	(	const FXString &	expression,
		const FXString &	variables = `FXString::null`,
		FXExpressionError *	error = `NULL`
	)

Compile expression; if error is not NULL, error code is returned.

FX::FXExpression::~FXExpression ( )

Delete.

FXExpression& FX::FXExpression::operator= ( const FXExpression & orig )

Assign another expression to this one.

bool FX::FXExpression::empty ( ) const [inline]

See if expression is empty.

FXdouble FX::FXExpression::evaluate ( const FXdouble * args = NULL )

Evaluate expression with given arguments, if any.

FXExpressionError FX::FXExpression::parse	(	const FXchar *	expression,
		const FXchar *	variables = `NULL`
	)

Parse expression, return error code if syntax error is found.

FXExpressionError FX::FXExpression::parse	(	const FXString &	expression,
		const FXString &	variables = `FXString::null`
	)

Parse expression, return error code if syntax error is found.

static const FXchar* FX::FXExpression::getError ( FXExpressionError err ) [inline, static]

Returns error code for given error.
