Method Details

exactRef

public Ref exactRef(String name)
             throws IOException

Read a single reference.

Unlike RefDatabase.findRef(String), this method expects an unshortened reference name and does not search using the standard RefDatabase.SEARCH_PATH.

Overrides:

exactRef in class DfsReftableDatabase

Parameters:

name - the unabbreviated name of the reference.

Returns:

the reference (if it exists); else null.

Throws:

IOException - the reference space cannot be accessed.

getRefs

public Map<String,Ref> getRefs(String prefix)
                        throws IOException

Get a section of the reference namespace.

Overrides:

getRefs in class DfsReftableDatabase

Parameters:

prefix - prefix to search the namespace with; must end with /. If the empty string (RefDatabase.ALL), obtain a complete snapshot of all references.

Returns:

modifiable map that is a complete snapshot of the current reference namespace, with prefix removed from the start of each key. The map can be an unsorted map.

Throws:

IOException - the reference space cannot be accessed.

getRefsByPrefix

public List<Ref> getRefsByPrefix(String prefix)
                          throws IOException

Returns refs whose names start with a given prefix.

The default implementation uses RefDatabase.getRefs(String). Implementors of RefDatabase should override this method directly if a better implementation is possible.

Overrides:

getRefsByPrefix in class DfsReftableDatabase

Parameters:

prefix - string that names of refs should start with; may be empty (to return all refs).

Returns:

immutable list of refs whose names start with prefix.

Throws:

IOException - the reference space cannot be accessed.

getRefsByPrefixWithExclusions

public List<Ref> getRefsByPrefixWithExclusions(String include,
 Set<String> excludes)
                                        throws IOException

Returns refs whose names start with a given prefix excluding all refs that start with one of the given prefixes.

The default implementation is not efficient. Implementors of RefDatabase should override this method directly if a better implementation is possible.

Overrides:

getRefsByPrefixWithExclusions in class DfsReftableDatabase

Parameters:

include - string that names of refs should start with; may be empty.

excludes - strings that names of refs can't start with; may be empty.

Returns:

immutable list of refs whose names start with prefix and none of the strings in exclude.

Throws:

IOException - the reference space cannot be accessed.

getTipsWithSha1

public Set<Ref> getTipsWithSha1(ObjectId id)
                         throws IOException

Returns all refs that resolve directly to the given ObjectId. Includes peeled ObjectIds. This is the inverse lookup of RefDatabase.exactRef(String...).

The default implementation uses a linear scan. Implementors of RefDatabase should override this method directly if a better implementation is possible.

Overrides:

getTipsWithSha1 in class DfsReftableDatabase

Parameters:

id - ObjectId to resolve

Returns:

a Set of Refs whose tips point to the provided id.

Throws:

IOException - the reference space cannot be accessed.
