Constructor Detail

PlotCommit

protected PlotCommit(AnyObjectId id)

Create a new commit.

Parameters:

id - the identity of this commit.

Method Detail

addForkingOffLane

void addForkingOffLane(PlotLane f)

addPassingLane

void addPassingLane(PlotLane c)

addMergingLane

void addMergingLane(PlotLane m)

addLane

private static PlotLane[] addLane(PlotLane l,
                                  PlotLane[] lanes)

addChild

void addChild(PlotCommit c)

getChildCount

public final int getChildCount()

Get the number of child commits listed in this commit.

Returns:

number of children; always a positive value but can be 0.

getChild

public final PlotCommit getChild(int nth)

Get the nth child from this commit's child list.

Parameters:

nth - child index to obtain. Must be in the range 0 through getChildCount()-1.

Returns:

the specified child.

Throws:

java.lang.ArrayIndexOutOfBoundsException - an invalid child index was specified.

isChild

public final boolean isChild(PlotCommit c)

Determine if the given commit is a child (descendant) of this commit.

Parameters:

c - the commit to test.

Returns:

true if the given commit built on top of this commit.

getRefCount

public final int getRefCount()

Get the number of refs for this commit.

Returns:

number of refs; always a positive value but can be 0.

getRef

public final Ref getRef(int nth)

Get the nth Ref from this commit's ref list.

Parameters:

nth - ref index to obtain. Must be in the range 0 through getRefCount()-1.

Returns:

the specified ref.

Throws:

java.lang.ArrayIndexOutOfBoundsException - an invalid ref index was specified.

getLane

public final L getLane()

Obtain the lane this commit has been plotted into.

Returns:

the assigned lane for this commit.

reset

public void reset()

Reset this commit to allow another RevWalk with the same instances.

Subclasses must call super.reset() to ensure the basic information can be correctly cleared out.

Overrides:

reset in class RevCommit
