Method Detail

add

public abstract void add(RevCommit c)

Add a commit to the queue.

This method always adds the commit, even if it is already in the queue or previously was in the queue but has already been removed. To control queue admission use add(RevCommit, RevFlag).

Parameters:

c - commit to add.

add

public final void add(RevCommit c,
                      RevFlag queueControl)

Add a commit if it does not have a flag set yet, then set the flag.

This method permits the application to test if the commit has the given flag; if it does not already have the flag than the commit is added to the queue and the flag is set. This later will prevent the commit from being added twice.

Parameters:

c - commit to add.

queueControl - flag that controls admission to the queue.

addParents

public final void addParents(RevCommit c,
                             RevFlag queueControl)

Add a commit's parents if one does not have a flag set yet.

This method permits the application to test if the commit has the given flag; if it does not already have the flag than the commit is added to the queue and the flag is set. This later will prevent the commit from being added twice.

Parameters:

c - commit whose parents should be added.

queueControl - flag that controls admission to the queue.

next

public abstract RevCommit next()

Return the next commit to the application, or the next generator.

Remove the first commit from the queue.

Specified by:

next in class Generator

Returns:

next available commit; null if no more are to be returned.

clear

public abstract void clear()

Remove all entries from this queue.

everbodyHasFlag

abstract boolean everbodyHasFlag(int f)

anybodyHasFlag

abstract boolean anybodyHasFlag(int f)

outputType

int outputType()

Description copied from class: Generator

Obtain flags describing the output behavior of this generator.

Specified by:

outputType in class Generator

Returns:

one or more of the constants declared in this class, describing how this generator produces its results.

describe

protected static void describe(java.lang.StringBuilder s,
                               RevCommit c)

Describe this queue

Parameters:

s - a StringBuilder

c - a RevCommit
