C# Class GitSharp.Core.ObjectDatabase

Abstraction of arbitrary object storage. An object database stores one or more Git objects, indexed by their unique ObjectId. Optionally an object database can reference one or more alternates; other ObjectDatabase instances that are searched in addition to the current database. Databases are usually divided into two halves: a half that is considered to be fast to search, and a half that is considered to be slow to search. When alternates are present the fast half is fully searched (recursively through all alternates) before the slow half is considered.

Public Methods

Method Description
Dispose ( ) : void
OpenObjectInAllPacks ( ICollection @out, GitSharp.Core.WindowCursor windowCursor, AnyObjectId objectId ) : void

Open the object from all packs containing it. If any alternates are present, their packs are also considered.
OpenObjectInAllPacksImplementation ( ICollection @out, GitSharp.Core.WindowCursor windowCursor, AnyObjectId objectId ) : void

Open the object from all packs containing it. If any alternates are present, their packs are also considered.
close ( ) : void

Close any resources held by this database and its active alternates.
closeAlternates ( ) : void

Fully close all loaded alternates and clear the alternate list.
closeSelf ( ) : void

Close any resources held by this database only; ignoring alternates. To fully close this database and its referenced alternates, the caller should instead invoke close().
create ( ) : void

Initialize a new object database at this location.
exists ( ) : bool

Gets if this database is already created; If it returns false, the caller should invoke create to create this database location.
getAlternates ( ) : GitSharp.Core.ObjectDatabase[]

Get the alternate databases known to this database.
hasObject ( AnyObjectId objectId ) : bool

Does the requested object exist in this database? Alternates (if present) are searched automatically.
hasObject1 ( AnyObjectId objectId ) : bool

Fast half of hasObject(AnyObjectId).
hasObject2 ( string objectName ) : bool

Slow half of hasObject(AnyObjectId).
loadAlternates ( ) : GitSharp.Core.ObjectDatabase[]

Load the list of alternate databases into memory. This method is invoked by getAlternates() if the alternate list has not yet been populated, or if closeAlternates() has been called on this instance and the alternate list is needed again. If the alternate array is empty, implementors should consider using the constant NoAlternates.
openObject ( GitSharp.Core.WindowCursor curs, AnyObjectId objectId ) : GitSharp.Core.ObjectLoader

Open an object from this database. Alternates (if present) are searched automatically.
openObject1 ( GitSharp.Core.WindowCursor curs, AnyObjectId objectId ) : GitSharp.Core.ObjectLoader

Fast half of openObject(WindowCursor, AnyObjectId).
openObject2 ( GitSharp.Core.WindowCursor curs, string objectName, AnyObjectId objectId ) : GitSharp.Core.ObjectLoader

Slow half of openObject(WindowCursor, AnyObjectId).
tryAgain1 ( ) : bool

true if the fast-half search should be tried again.
