Examples of mondrian.olap.Member

mondrian.olap.Member
A Member is a 'point' on a dimension of a cube. Examples are [Time].[1997].[January], [Customer].[All Customers], [Customer].[USA].[CA], [Measures].[Unit Sales].
Every member belongs to a {@link Level} of a {@link Hierarchy}. Members except the root member have a parent, and members not at the leaf level have one or more children.
Measures are a special kind of member. They belong to their own dimension, [Measures].
There are also special members representing the 'All' value of a hierarchy, the null value, and the error value.
Members can have member properties. Their {@link Level#getProperties}defines which are allowed.
