Method Detail

getBufferSize

public int getBufferSize()

Description copied from interface: ComponentMapping

Get the number of elements which are buffered before being stored persistently by the index

Returns:

the number of elements which are buffered before being stored persistently by the index

rebuildMapping

public void rebuildMapping(boolean online)
                    throws OnlineRebuildNotSupportedException

Description copied from interface: ComponentMapping

Rebuilds and optimzes the mapping (for instance an index).

Parameters:

online - - if true allows concurrent modifications to this ComponentMapping while rebuilding. If false this ComponentMapping is locked and no modifications are allowed during the rebuild.

Throws:

OnlineRebuildNotSupportedException
