public interface CDOBranch extends CDOBranchPoint, CDONameProvider, org.eclipse.net4j.util.container.IContainer<CDOBranch>, java.lang.Comparable<CDOBranch>, IAdaptable
Represents a stream of changes that is isolated from other streams of changes.A branch starts at a fixed
basepoint and ends at a floatingheadpoint. Between these two points there can be a number of otherbranch points:-
Commit infosare points in a branch that represent commit operations. -
Branch tagsare named points in a branch. -
Base pointsof sub branches of a branch.

getID
int getID()
Returns the ID of this branch.The
main branchhas the fixed ID 0 (zero),Local brancheshave negative IDs and normal branches have positive IDs.
-
getName
java.lang.String getName()
Returns the name of this branch as specified when it was created withcreateBranch()orMAIN_BRANCH_NAMEif this branch is themain branch.- Specified by:
getNamein interfaceCDONameProvider
-
setName
void setName(java.lang.String name)
- Since:
- 4.4
-
getPathName
java.lang.String getPathName()
Returns the fully qualified path name of this branch, a concatenation of the names of all branches from themain branchto this branch, separated byslashes("/" characters). Example: "MAIN/team1/smith".
-
getBasePath
CDOBranchPoint[] getBasePath()
Returns an array of thebasebranch points starting from the base of themain branchdown to and including the base of this branch.
-
getBase
CDOBranchPoint getBase()
Returns the immutable base branch point of this branch, the point in the parent branch that marks the creation of this branch.The base of the
main branchmarks the creation of therepository.- See Also:
getHead(),getPoint(long)
-
getHead
CDOBranchPoint getHead()
Returns the floating end point of this branch, a pair of this branch and the fixed special time stampunspecified.- See Also:
getBase(),getPoint(long)
-
getPoint
CDOBranchPoint getPoint(long timeStamp)
Returns the branch point in this branch with the given time stamp.This factory method never returns
null.- See Also:
getBase(),getHead(),getVersion(int)

-
getBranch
CDOBranch getBranch(java.lang.String path)
Returns the sub branch of this branch with the given relative path, ornullif no sub branch with this path exists in this branch.The path name is the concatenation of the names of all branches from a direct sub branch of this branch, separated by
slashes("/" characters). Example: "team1/smith".
-
