%DeepSee.Query.axis

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

This class defines an axis within a DeepSee query.

Properties​

query​

Relationship query As %DeepSee.Query.query(XMLPROJECTION = "none") [ Cardinality = one, Inverse = axes ];

Query that this axis belongs to.

subqueries​

Property subqueries As list Of %DeepSee.ResultSet(XMLPROJECTION = "NONE");

Collection of subqueries associated with this axis.

nonEmpty​

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

If true, then empty tuples (e.g. complete rows or columns) are removed from the results of the query.
This is equivalent to the MDX "NON EMPTY" key word.

context​

Property context As %String(VALUELIST = "axis,filter,filterAxis", XMLPROJECTION = "none") [ InitialExpression = "axis" ];

Reference to the context where this object is used in the overall query structure

%dependencies​

Property %dependencies As %String [ Internal, MultiDimensional ];

List of facts this axis depends on.

%cmbrIndex​

Property %cmbrIndex As %String [ Internal, MultiDimensional ];

List of current member markers along this axis.

%originalSpec​

Property %originalSpec As %String;

Copy of the original string used to produce this axis object

%AxisKey​

Property %AxisKey As %String;

Once calculated the axis key is stabilized for this particular object.

Methods​

%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) As %Status [ Internal ]

Execute and build the axes output for this axis.

%CountTerms​

Method %CountTerms(pCubeIndex As %String, pAxisKey As %String, Output pStatus As %Status) As %Integer

Review the contents of an axis and count the number of terms within it that will translate into bit operations. This performs a blind count and ignores chain/child structures so it can be called at any stage of axis construction.

%IsSearch​

Method %IsSearch(Output pSC As %Status) As %Boolean [ Internal ]

Incates whether or not this axis is a placeholder %SEARCH axis.

%CopyComplexAggregate​

ClassMethod %CopyComplexAggregate(pCube As %String, pKey As %String) As %Status [ Internal ]

If the axis contains a complex aggregate, copy it and set it aside in a special
^DeepSee.Cache.Axis(cubeKey,axisKey,"agg")
node. A complex aggregate is marked by the presence of $LI(node,24).
