Field Detail

cubeSource

protected final RolapCubeHierarchy.RolapCubeSqlMemberSource cubeSource

cubeSource is passed as our member builder

rolapCubeCacheHelper

protected MemberCacheHelper rolapCubeCacheHelper

this cache caches RolapCubeMembers that are light wrappers around shared and non-shared Hierarchy RolapMembers. The inherited cacheHelper object contains non-shared hierarchy RolapMembers. non-shared hierarchy RolapMembers are created when a member lookup involves the Cube's fact table.

Constructor Detail

NoCacheRolapCubeHierarchyMemberReader

public NoCacheRolapCubeHierarchyMemberReader()

Method Detail

getMemberBuilder

public TupleReader.MemberBuilder getMemberBuilder()

Specified by:

getMemberBuilder in interface MemberReader

Overrides:

getMemberBuilder in class NoCacheMemberReader

getRolapCubeMemberCacheHelper

public MemberCacheHelper getRolapCubeMemberCacheHelper()

Specified by:

getRolapCubeMemberCacheHelper in interface RolapCubeHierarchy.RolapCubeHierarchyMemberReader

getRootMembers

public List<RolapMember> getRootMembers()

Description copied from interface: MemberSource

Returns all members of this hierarchy which do not have a parent, sorted by ordinal.

If this object supports cache-writeback, also writes these members to the cache.

Specified by:

getRootMembers in interface MemberSource

Overrides:

getRootMembers in class NoCacheMemberReader

Returns:

List of RolapMembers

readMemberChildren

protected void readMemberChildren(List<RolapMember> parentMembers,
                                  List<RolapMember> children,
                                  MemberChildrenConstraint constraint)

Description copied from class: NoCacheMemberReader

Reads the children of member into result.

Overrides:

readMemberChildren in class NoCacheMemberReader

Parameters:

parentMembers - Members whose children to read

children - Children are written here, in order

constraint - restricts the returned members if possible (optional optimization)

getMemberChildren

public Map<? extends Member,Access> getMemberChildren(List<RolapMember> parentMembers,
                                                            List<RolapMember> children,
                                                            MemberChildrenConstraint constraint)

Description copied from interface: MemberReader

Populates a list of the children of a given set of Members, optionally applying a constraint.

Specified by:

getMemberChildren in interface MemberReader

Overrides:

getMemberChildren in class NoCacheMemberReader

Parameters:

parentMembers - List of members whose children to find

children - List to populate with members

constraint - Constraint

Returns:

After populating the list passed as an argument, this method returns a map of the members it just populated along with the Access information applicable. If no access control applies to the member, the map will contain null values.

getMembersInLevel

public List<RolapMember> getMembersInLevel(RolapLevel level,
                                           TupleConstraint constraint)

Description copied from interface: MemberReader

Returns the members in the given Level, optionally applying a constraint.

Specified by:

getMembersInLevel in interface MemberReader

Overrides:

getMembersInLevel in class NoCacheMemberReader

Parameters:

level - Level

constraint - Constraint

Returns:

list of members

lookupCubeMember

public RolapCubeMember lookupCubeMember(RolapCubeMember parent,
                                        RolapMember member,
                                        RolapCubeLevel level)

Specified by:

lookupCubeMember in interface RolapCubeHierarchy.RolapCubeHierarchyMemberReader

getMemberCount

public int getMemberCount()

Description copied from interface: MemberSource

Returns an estimate of number of members in this hierarchy.

Specified by:

getMemberCount in interface MemberSource

Overrides:

getMemberCount in class NoCacheMemberReader
