class %DeepSee.Query.expression extends group
This class defines an expression within a DeepSee query.
An expression belongs to a set. Though an expression is a group, it only makes use of its first two children.
Format string to apply to this member.property isScalarFunction as %Boolean(XMLPROJECTION="attribute") [ InitialExpression = 0 ];
Set true if this operator is a scalar function.property label as %DeepSee.Datatype.string(XMLPROJECTION="attribute") [ InitialExpression = "Expression" ];
Axis label used for this expression.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").property scalarArgCount as %String(XMLPROJECTION="attribute") [ InitialExpression = 0 ];
If this operator is a scalar function, this is the number of expected arguments. This takes the form "arguments:optional arguments".property solveOrder as %Integer(MINVAL=0,XMLPROJECTION="attribute");
Solve order to apply to this expression (applied from outer calcMember).
