Class CassFolderHandler

java.lang.Object

rapture.repo.cassandra.CassFolderHandler

public class CassFolderHandler
extends java.lang.Object

A folder handler stores rows by prefix

When we add a prefix we store entries for each entry in that hierarchy - storing the next level down value at each point as a column name. The value of each column is a count of the number of children - so often we may have to attempt to retrieve the value to update it by one - and if the value is decremented to zero we should remove that cell intersection. Documents have a value of -1
