org.eclipse.emf.cdo.spi.common.commit.CDOChangeSetSegment

All Implemented Interfaces:: CDOBranchPoint, CDOBranchProvider, CDOTimeProvider

public class CDOChangeSetSegment extends Object implements CDOBranchPoint

A time interval on one branch used to divide a history traversal into branch-local segments. The static traversal helpers follow branch bases from an end point and report each interval to a handler, which supports change-set calculations across forks.
