Detailed Description

The LiteralOperand is defined in OPC UA 1.05 part 4, 7.7.4.3. It contains a literal value that is to be used as operand for filters.

Setting the type should be done to match the expected types on the server. Otherwise the type will be guessed and may lead to errors because it does not match on the server.
