org.olap4j.CellSetAxis
Axis of a CellSet.
A cell set has the same number of axes as the MDX statement which was executed to produce it. For example, a typical cell set, resulting from an MDX query with COLUMNS and ROWS expressions is two-dimensional, and therefore has two axes.

Each axis is an ordered collection of members or tuples. Each member or tuple on an axis is called a {@link Position}.

The positions on the cell set axis can be accessed sequentially or random-access. Use the {@link #getPositions()} method to return a list forrandom access, or the {@link #iterator()} method to obtain an iterator forsequential access. @author jhyde @version $Id: CellSetAxis.java 315 2010-05-29 00:56:11Z jhyde $ @since Aug 22, 2006
