                              RolapLevel childLevel,
                              Object value,
                              Object captionValue,

                              int columnOffset)
                       throws SQLException

Description copied from interface: TupleReader.MemberBuilder

Creates a new member (together with its properties).

Specified by:

makeMember in interface TupleReader.MemberBuilder

Parameters:

parentMember - Parent member

childLevel - Child level

value - Member value

captionValue - Caption

parentChild - Whether a parent-child hierarchy

stmt - SQL statement

key - Member key

columnOffset - Column ordinal (0-based)

Returns:

new member

Throws:

SQLException - on error

getMemberCache

public mondrian.rolap.MemberCache getMemberCache()

Description copied from interface: TupleReader.MemberBuilder

Returns the MemberCache to look up members before creating them.

Specified by:

getMemberCache in interface TupleReader.MemberBuilder

Returns:

member cache

getMemberCacheLock

public Object getMemberCacheLock()

use the same lock in the RolapCubeMemberSource as the RolapCubeHiearchyMemberReader to avoid deadlocks

Specified by:

getMemberCacheLock in interface TupleReader.MemberBuilder

Returns:

Object to lock

allMember

public RolapMember allMember()

Description copied from interface: TupleReader.MemberBuilder

Returns the 'all' member of the hierarchy.

Specified by:

allMember in interface TupleReader.MemberBuilder

Returns:

The 'all' member

getHierarchy

public RolapHierarchy getHierarchy()

Description copied from interface: MemberSource

Returns the hierarchy that this source is reading for.

Specified by:

getHierarchy in interface MemberSource

setCache

public boolean setCache(mondrian.rolap.MemberCache cache)

Description copied from interface: MemberSource

Sets the cache which this MemberSource will write to.

Cache-writeback is optional (for example, SqlMemberSource supports it, and ArrayMemberSource does not), and the return value from this method indicates whether this object supports it.

If this method returns true, the MemberSource.getMembers(), MemberSource.getRootMembers() and MemberSource.getMemberChildren(mondrian.rolap.RolapMember, java.util.List<mondrian.rolap.RolapMember>) methods must write to the cache, in addition to returning members as a return value.

Specified by:

setCache in interface MemberSource

Parameters:

cache - The MemberCache which the caller would like this MemberSource to write to.

Returns:

Whether this MemberSource supports cache-writeback.

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
