QString QgsSymbolLayerV2Utils::fieldOrExpressionFromExpression ( QgsExpression expression)
static

Return a field name if the whole expression is just a name of the field .

Returns full expression string if the expression is more complex than just one field. Using just expression->expression() method may return quoted field name, but that is not wanted for saving (due to backward compatibility) or display in GUI.

QgsExpression * QgsSymbolLayerV2Utils::fieldOrExpressionToExpression ( const QString &  fieldOrExpression)
static

Return a new valid expression instance for given field or expression string.

If the input is not a valid expression, it is assumed that it is a field name and gets properly quoted. If the string is empty, returns null pointer. This is useful when accepting input which could be either a non-quoted field name or expression.
