%DeepSee.Query.expression

Class %DeepSee.Query.expression Extends group [ System = 3 ]

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.

Properties​

operator​

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").

isScalarFunction​

Property isScalarFunction As %Boolean(XMLPROJECTION = "attribute") [ InitialExpression = 0 ];

Set true if this operator is a scalar function.

scalarArgCount​

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".

label​

Property label As %DeepSee.Datatype.string(XMLPROJECTION = "attribute") [ InitialExpression = "Expression" ];

Axis label used for this expression.

formatString​

Property formatString As %String(MAXLEN = 255, XMLPROJECTION = "attribute");

Format string to apply to this member.

solveOrder​

Property solveOrder As %Integer(MINVAL = 0, XMLPROJECTION = "attribute");

Solve order to apply to this expression (applied from outer calcMember).

Methods​

%GetType​

Method %GetType() As %String

Return the type of this node.

%ToString​

Method %ToString(Output pSC As %Status) As %String

Convert this node to its text representation.

%ProcessAxes​

Method %ProcessAxes(pCube As %String, pKey As %String, ByRef pNodeNo As %Integer, Output pNewNodeNo As %Integer, pParent As %Integer, pVisible As %Boolean = 1) As %Status [ Internal ]

Execute and build the axes output for this expression.

%ProcessFilter​

Method %ProcessFilter(ByRef pFilterTree As %List, pCube As %String, ByRef pNodeNo As %Integer, Output pNewNodeNo As %Integer, pParent As %Integer) As %Status [ Internal ]

Process the filter output for this expression.
