A class or parent that contributes (via inheritance) to the definition of an object. For class-based hierarchies, the ancestors of an object are its class(es) and all the superclasses of its class(es). For prototype-based hierarchies, the ancestors of an object are its parent(s) and the ancestors of its parent(s).
1. A tree data structure term that means some node in the succession of parent nodes on a path to the root. i.e., a node's parent and parent's parent are both ancestors of the node. 2. A reserved Lingo script property that can be used to establish inheritance.
An ancestor of a segment is a segment that refers, either directly or indirectly, to a given segment. If segment 1 contains a call_segment element referencing segment 2, and segment 2 contains a call_segment element referencing segment 3, both segments 1 and 2 would be ancestors of segment 3. Segment 2 would also be the parent segment of segment 3. Compare descendant.
A value at any level higher than a given value in a hierarchy. For example, in a Time dimension, the value 2002 might be the ancestor of the values Q1-02 and Jan-02. In a dimension hierarchy, the data value of the ancestor is the aggregated value of the data values of its descendants. Contrast with descendant. See also hierarchy, level, parent.
