Properties

• property %AxisKey as %String;

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

• property %originalSpec as %String;

Copy of the original string used to produce this axis object

• 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

• 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.

• relationship query as %DeepSee.Query.query(XMLPROJECTION="none") [ Inverse = axes,Cardinality = one ];

Query that this axis belongs to.

• property subqueries as list of %DeepSee.ResultSet(XMLPROJECTION="NONE");

Collection of subqueries associated with this axis.

Methods

• 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.

• method %ToString(Output pSC As %Status) as %String

Convert this node to its text representation.
