  mondrian.rolap.agg.SegmentHeader.ConstrainedColumn

All Implemented Interfaces:

Serializable

Enclosing class:

SegmentHeader

public static class SegmentHeader.ConstrainedColumn
extends Object
implements Serializable

Constrained columns are part of the SegmentHeader and SegmentCache. They uniquely identify a constrained column within a segment. Each segment can have many constrained columns. Each column can be constrained by multiple values at once (similar to a SQL in() predicate).

They are immutable and serializable.
