Macro Definition Documentation

◆ DEFINE_EXPRESSION_NODE_TYPE

#define DEFINE_EXPRESSION_NODE_TYPE	(		TYPE,
			... )

Value:

template<> struct TGetExpressionNodeTypeId<TYPE>\
{\
    static const FGuid& GetTypeId()\
    {\
        static FGuid Global(__VA_ARGS__);\
        return Global;\
    }\
};

Helper macro to define the necessary template specialization for a particular expression node type Variable length arguments are passed the FGuid constructor. Must be unique per type

Function Documentation

◆ TOptional< FExpressionError >()

typedef TOptional< FExpressionError > ( FExpressionDefinition ) &

Typedef that defines a function used to consume tokens Definitions may add FExpressionNodes parsed from the provided consumer's stream, or return an optional error. Where a definition performs no mutable operations, subsequent token definitions will be invoked.
