Functions
ExpressionItem	NES::Attribute (std::string name)
	Attribute(name) allows the user to reference a field in his expression. Attribute("f1") < 10 todo rename to field if conflict with legacy code is resolved. More...

ExpressionItem	NES::Attribute (std::string name, BasicType type)
	Attribute(name, type) allows the user to reference a field, with a specific type in his expression. Field("f1", Int) < 10. todo remove this case if we added type inference at Runtime from the operator tree. todo rename to field if conflict with legacy code is resolved. More...

ExpressionNodePtr	NES::WHEN (const ExpressionNodePtr &conditionExp, const ExpressionNodePtr &valueExp)
	WHEN(condition,value) can only be used as part of the left vector in a CASE() expression. Allows to only return the value expression if condition is met. More...

ExpressionNodePtr	NES::WHEN (ExpressionItem conditionExp, ExpressionNodePtr valueExp)

ExpressionNodePtr	NES::WHEN (ExpressionNodePtr conditionExp, ExpressionItem valueExp)

ExpressionNodePtr	NES::WHEN (ExpressionItem conditionExp, ExpressionItem valueExp)

ExpressionNodePtr	NES::CASE (const std::vector< ExpressionNodePtr > &whenExpressions, ExpressionNodePtr defaultValueExp)
	CASE({WHEN(condition,value),WHEN(condition, value)} , value) allows to evaluate all WHEN expressions from the vector list and only return the first one where the condition evaluated to true, or the value of the default expression. The CASE({WHEN()},default) is evaluated as a concatenated ternary operator in C++. More...
