org.eclipse.jgit.revwalk.RevCommitList<PlotCommit<L>>

org.eclipse.jgit.revplot.PlotCommitList<L>

Type Parameters:

L - type of lane used by the application.

All Implemented Interfaces:

Iterable<PlotCommit<L>>, Collection<PlotCommit<L>>, List<PlotCommit<L>>

public class PlotCommitList<L extends PlotLane>
extends RevCommitList<PlotCommit<L>>

An ordered list of PlotCommit subclasses.

Commits are allocated into lanes as they enter the list, based upon their connections between descendant (child) commits and ancestor (parent) commits.

The source of the list must be a PlotWalk and RevCommitList.fillTo(int) must be used to populate the list.

Method Detail

clear

public void clear()

Specified by:

clear in interface Collection<PlotCommit<L extends PlotLane>>

Specified by:

clear in interface List<PlotCommit<L extends PlotLane>>

Overrides:

clear in class RevCommitList<PlotCommit<L extends PlotLane>>

source

public void source(RevWalk w)

Description copied from class: RevCommitList

Set the revision walker this list populates itself from.

Overrides:

source in class RevCommitList<PlotCommit<L extends PlotLane>>

Parameters:

w - the walker to populate from.

RevCommitList.fillTo(int)

findPassingThrough

public void findPassingThrough(PlotCommit<L> currCommit,
                      Collection<L> result)

Find the set of lanes passing through a commit's row.

Lanes passing through a commit are lanes that the commit is not directly on, but that need to travel through this commit to connect a descendant (child) commit to an ancestor (parent) commit. Typically these lanes will be drawn as lines in the passed commit's box, and the passed commit won't appear to be connected to those lines.

This method modifies the passed collection by adding the lanes in any order.

Parameters:

currCommit - the commit the caller needs to get the lanes from.

result - collection to add the passing lanes into.

enter

protected void enter(int index,
         PlotCommit<L> currCommit)

Description copied from class: RevCommitList

Optional callback invoked when commits enter the list by fillTo.

This method is only called during RevCommitList.fillTo(int).

Overrides:

enter in class RevCommitList<PlotCommit<L extends PlotLane>>

Parameters:

index - the list position this object will appear at.

currCommit - the object being added (or set) into the list.

createLane

protected L createLane()

Returns:

a new Lane appropriate for this particular PlotList.

recycleLane

protected void recycleLane(L lane)

Return colors and other reusable information to the plotter when a lane is no longer needed.

Parameters:

lane -
