Constructor Detail

SphereBranchImpl

protected SphereBranchImpl(org.chronos.chronograph.api.branch.GraphBranch backingBranch,
                           SphereBranch origin)

Method Detail

createMasterBranch

public static SphereBranchImpl createMasterBranch(org.chronos.chronograph.api.branch.GraphBranch backingMasterBranch)

createBranch

public static SphereBranchImpl createBranch(org.chronos.chronograph.api.branch.GraphBranch backingBranch,
                                            SphereBranch origin)

getName

public java.lang.String getName()

Description copied from interface: SphereBranch

Returns the name of this branch, which also acts as its unique identifier.

Specified by:

getName in interface SphereBranch

Returns:

The branch name. Never null. Branch names are unique.

getOrigin

public SphereBranch getOrigin()

Description copied from interface: SphereBranch

Returns the branch from which this branch originates.

Specified by:

getOrigin in interface SphereBranch

Returns:

The origin (parent) branch. May be null if this branch is the master branch.

getBranchingTimestamp

public long getBranchingTimestamp()

Description copied from interface: SphereBranch

Returns the timestamp at which this branch was created from the origin (parent) branch.

Specified by:

getBranchingTimestamp in interface SphereBranch

Returns:

The branching timestamp. Never negative.

getOriginsRecursive

public java.util.List<SphereBranch> getOriginsRecursive()

Description copied from interface: SphereBranch

Returns the list of direct and transitive origin branches.

The first entry in the list will always be the master branch. The remaining entries are the descendants of the previous branch in the list which are also direct or transitive origins of the current branch.

For example, if there were the following branching actions:

1. master is forked into new branch A
2. A is forked into new branch B
3. B is forked into new branch C

... and C.getOriginsRecursive() is invoked, then the returned list will consist of [master, A, B] (in exactly this order).

Specified by:

getOriginsRecursive in interface SphereBranch

Returns:

The list of origin branches. Will be empty for the master branch, and will start with the master branch for all other branches. Never null. The returned list is a calculated object which may freely be modified without changing any internal state.

getNow

public long getNow()

Description copied from interface: SphereBranch

Returns the "now" timestamp on this branch, i.e. the timestamp at which the last full commit was successfully executed.

Specified by:

getNow in interface SphereBranch

Returns:

The "now" timestamp. The minimum is the branching timestamp (or zero for the master branch). Never negative.

hashCode

public int hashCode()

Overrides:

hashCode in class java.lang.Object

equals

public boolean equals(java.lang.Object obj)

Overrides:

equals in class java.lang.Object
