Constructor Detail

NameRevCommand

protected NameRevCommand(Repository repo)

Create a new name-rev command.

Parameters:

repo - the Repository

Method Detail

call

public java.util.Map<ObjectId,java.lang.String> call()
                                              throws GitAPIException

Execute the command

Specified by:

call in interface java.util.concurrent.Callable<java.util.Map<ObjectId,java.lang.String>>

Specified by:

call in class GitCommand<java.util.Map<ObjectId,java.lang.String>>

Throws:

GitAPIException

add

public NameRevCommand add(ObjectId id)
                   throws MissingObjectException,
                          JGitInternalException

Add an object to search for.

Parameters:

id - object ID to add.

Returns:

this

Throws:

MissingObjectException - the object supplied is not available from the object database.

JGitInternalException - a low-level exception of JGit has occurred. The original exception can be retrieved by calling Throwable.getCause().

add

public NameRevCommand add(java.lang.Iterable<ObjectId> ids)
                   throws MissingObjectException,
                          JGitInternalException

Add multiple objects to search for.

Parameters:

ids - object IDs to add.

Returns:

this

Throws:

MissingObjectException - the object supplied is not available from the object database.

JGitInternalException - a low-level exception of JGit has occurred. The original exception can be retrieved by calling Throwable.getCause().

addPrefix

public NameRevCommand addPrefix(java.lang.String prefix)

Add a ref prefix to the set that results must match.

If an object matches multiple refs equally well, the first matching ref added with addRef(Ref) is preferred, or else the first matching prefix added by addPrefix(String).

Parameters:

prefix - prefix to add; see RefDatabase.getRefs(String)

Returns:

this

addAnnotatedTags

public NameRevCommand addAnnotatedTags()

Add all annotated tags under refs/tags/ to the set that all results must match.

Calls addRef(Ref); see that method for a note on matching priority.

Returns:

this

Throws:

JGitInternalException - a low-level exception of JGit has occurred. The original exception can be retrieved by calling Throwable.getCause().

addRef

public NameRevCommand addRef(Ref ref)

Add a ref to the set that all results must match.

If an object matches multiple refs equally well, the first matching ref added with addRef(Ref) is preferred, or else the first matching prefix added by addPrefix(String).

Parameters:

ref - ref to add.

Returns:

this

setMergeCost

NameRevCommand setMergeCost(int cost)
