    This method uses a double-checked locking idiom to avoid making the method fully synchronized, or potentially creating the same MemberReader more than once. Double-checked locking can cause issues if a second thread accesses the field without either a shared lock in place or the field being specified as volatile. In this case, hierarchyReaders is a ConcurrentHashMap, which internally uses volatile load semantics for read operations. This assures values written by one thread will be visible when read by others. http://en.wikipedia.org/wiki/Double-checked_locking

public void getMemberRange(Level level,
                           Member startMember,
                           Member endMember,

                                        Member m2)
```
    Description copied from interface: SchemaReader
    
    Compares a pair of Members according to their order in a prefix traversal. (that is, it is an ancestor or a earlier), is a sibling, or comes later in a prefix traversal.
    
    Specified by:
    
    compareMembersHierarchically in interface SchemaReader
    
    Returns:
    
    A negative integer if m1 is an ancestor, an earlier sibling of an ancestor, or a descendent of an earlier sibling, of m2; zero if m1 is a sibling of m2; a positive integer if m1 comes later in the prefix traversal then m2.
  - getMemberParent
```
public Member getMemberParent(Member member)
```
    Description copied from interface: SchemaReader
    
    Returns the parent of member.
    
    Specified by:
    
    getMemberParent in interface SchemaReader
    
    Parameters:
    
    member - Member
    
    Returns:
    
    null if member is a root member
  - getMemberDepth
```
public int getMemberDepth(Member member)
```
    Description copied from interface: SchemaReader
    Returns the depth of a member.
    This may not be the same as member.getLevel(). getDepth() for three reasons:
    1. Access control. The most senior visible member has level 0. If the client is not allowed to see the "All" and "Nation" levels of the "Store" hierarchy, then members of the "State" level will have depth 0.
    2. Parent-child hierarchies. Suppose Fred reports to Wilma, and Wilma reports to no one. "All Employees" has depth 0, Wilma has depth 1, and Fred has depth 2. Fred and Wilma are both in the "Employees" level, which has depth 1.
    3. Ragged hierarchies. If Israel has only one, hidden, province then the depth of Tel Aviv, Israel is 2, whereas the depth of another city, San Francisco, CA, USA is 3.
    Specified by:
    
    getMemberDepth in interface SchemaReader
  - getMemberChildren
```
public List<Member> getMemberChildren(Member member)
```
    Description copied from interface: SchemaReader
    
    Returns direct children of member.
    
    Specified by:
    
    getMemberChildren in interface SchemaReader
  - getMemberChildren
```
public List<Member> getMemberChildren(Member member,
                                      Evaluator context)
```
    Description copied from interface: SchemaReader
    
    Returns direct children of member, optimized for NON EMPTY.
    If context == null then there is no context and all members are returned - then its identical to SchemaReader.getMemberChildren(Member). If context is not null, the resulting members may be restricted to those members that have a non empty row in the fact table for context. Wether or not optimization is possible depends on the SchemaReader implementation.
