Property methods: isScalarFunctionDisplayToLogical(), isScalarFunctionGet(), isScalarFunctionIsValid(), isScalarFunctionLogicalToDisplay(), isScalarFunctionLogicalToXSD(), isScalarFunctionNormalize(), isScalarFunctionSet(), isScalarFunctionXSDToLogical()
property label as %DeepSee.Datatype.string (XMLPROJECTION = "attribute") [ InitialExpression = "Expression" ];
Axis label used for this expression.
Property methods: labelDisplayToLogical(), labelGet(), labelIsValid(), labelLogicalToDisplay(), labelLogicalToOdbc(), labelNormalize(), labelSet()
property operator as %DeepSee.Datatype.string (MAXLEN = 25, XMLPROJECTION = "attribute");
Logical operator that is applied to the children of this expression. This can be an operator (such as "+", or a SCALAR function, such as "SQRT").
