C# 클래스 GitSharp.Core.DirectoryCache.DirCacheTree

Single tree record from the 'TREE' DirCache extension. A valid cache tree record contains the object id of a tree object and the total number of DirCacheEntry instances (counted recursively) from the DirCache contained within the tree. This information facilitates faster traversal of the index and quicker generation of tree objects prior to creating a new commit. An invalid cache tree record indicates a known subtree whose file entries have changed in ways that cause the tree to no longer have a known object id. Invalid cache tree records must be revalidated prior to use.

DirCacheTree ( ) : System
DirCacheTree ( byte @in, MutableInteger off, DirCacheTree myParent ) : System
contains ( byte a, int aOff, int aLen ) : bool
getChild ( int i ) : DirCacheTree	Get the i-th child cache tree.
getChildCount ( ) : int	Get the number of cached subtrees contained within this tree.
getEntrySpan ( ) : int	Get the number of entries this tree spans within the DirCache. If this tree is not valid (see isValid()) this method's return value is always strictly negative (less than 0) but is otherwise an undefined result.
getNameString ( ) : string	Get the tree's name within its parent. This method is not very efficient and is primarily meant for debugging and final output generation. Applications should try to avoid calling it, and if invoked do so only once per interesting entry, where the name is absolutely required for correct function.
getObjectId ( ) : ObjectId
getPathString ( ) : string	Get the tree's path within the repository. This method is not very efficient and is primarily meant for debugging and final output generation. Applications should try to avoid calling it, and if invoked do so only once per interesting entry, where the name is absolutely required for correct function.
isValid ( ) : bool	Determine if this cache is currently valid. A valid cache tree knows how many DirCacheEntry instances from the parent DirCache reside within this tree (recursively enumerated). It also knows the object id of the tree, as the tree should be readily available from the repository's object database.
nameLength ( ) : int
validate ( DirCacheEntry cache, int cCnt, int cIdx, int pathOff ) : void	Update (if necessary) this tree's entrySpan.
write ( byte tmp, TemporaryBuffer os ) : void
writeTree ( DirCacheEntry cacheEntry, int cIdx, int pathOffset, ObjectWriter ow ) : ObjectId	Write (if necessary) this tree to the object store.
