Types ¶
type Hash ¶
type Hash [20]byte
Hash SHA1 hased content
var ZeroHash Hash
ZeroHash is Hash with value zero
func ComputeHash ¶
func ComputeHash(t ObjectType, content []byte) Hash
ComputeHash compute the hash for a given ObjectType and content
type Object ¶
type Object interface {
Hash() Hash
Type() ObjectType
SetType(ObjectType)
Size() int64
SetSize(int64)
Reader() (ObjectReader, error)
Writer() (ObjectWriter, error)
}
Object is a generic representation of any git object
type ObjectIter ¶
ObjectIter is a generic closable interface for iterating over objects.
type ObjectLookupIter ¶
type ObjectLookupIter struct {
// contains filtered or unexported fields
}
ObjectLookupIter implements ObjectIter. It iterates over a series of object hashes and yields their associated objects by retrieving each one from object storage. The retrievals are lazy and only occur when the iterator moves forward with a call to Next().
The ObjectLookupIter must be closed with a call to Close() when it is no longer needed.
func NewObjectLookupIter ¶
func NewObjectLookupIter(storage ObjectStorage, series []Hash) *ObjectLookupIter
NewObjectLookupIter returns an object iterator given an object storage and a slice of object hashes.
func (*ObjectLookupIter) Close ¶
func (iter *ObjectLookupIter) Close()
Close releases any resources used by the iterator.
func (*ObjectLookupIter) Next ¶
func (iter *ObjectLookupIter) Next() (Object, error)
Next returns the next object from the iterator. If the iterator has reached the end it will return io.EOF as an error. If the object can't be found in the object storage, it will return ObjectNotFoundErr as an error. If the object is retreieved successfully error will be nil.
type ObjectReader ¶
type ObjectReader io.ReadCloser
ObjectReader is a generic representation of an object reader.
ObjectReader implements io.ReadCloser. Close should be called when finished with it.
type ObjectSliceIter ¶
type ObjectSliceIter struct {
// contains filtered or unexported fields
}
ObjectSliceIter implements ObjectIter. It iterates over a series of objects stored in a slice and yields each one in turn when Next() is called.
The ObjectSliceIter must be closed with a call to Close() when it is no longer needed.
func NewObjectSliceIter ¶
func NewObjectSliceIter(series []Object) *ObjectSliceIter
NewObjectSliceIter returns an object iterator for the given slice of objects.
func (*ObjectSliceIter) Close ¶
func (iter *ObjectSliceIter) Close()
Close releases any resources used by the iterator.
func (*ObjectSliceIter) Next ¶
func (iter *ObjectSliceIter) Next() (Object, error)
Next returns the next object from the iterator. If the iterator has reached the end it will return io.EOF as an error. If the object is retreieved successfully error will be nil.
type ObjectStorage ¶
type ObjectStorage interface {
New() (Object, error)
Set(Object) (Hash, error)
Get(Hash) (Object, error)
Iter(ObjectType) ObjectIter
}
ObjectStorage generic storage of objects
type ObjectType ¶
type ObjectType int8
ObjectType internal object type's
const ( CommitObject ObjectType = 1 TreeObject ObjectType = 2 BlobObject ObjectType = 3 TagObject ObjectType = 4 OFSDeltaObject ObjectType = 6 REFDeltaObject ObjectType = 7 )
func ParseObjectType ¶
func ParseObjectType(value string) (typ ObjectType, err error)
ParseObjectType parses a string representation of ObjectType. It returns an error on parse failure.
func (ObjectType) Bytes ¶
func (t ObjectType) Bytes() []byte
func (ObjectType) String ¶
func (t ObjectType) String() string
func (ObjectType) Valid ¶
func (t ObjectType) Valid() bool
Valid returns true if t is a valid ObjectType.
type ObjectWriter ¶
type ObjectWriter io.WriteCloser
ObjectWriter is a generic representation of an object writer.
ObjectWriter implements io.WriterCloser. Close should be called when finished with it.
type PermanentError ¶
type PermanentError struct {
Err error
}
func NewPermanentError ¶
func NewPermanentError(err error) *PermanentError
func (*PermanentError) Error ¶
func (e *PermanentError) Error() string
type UnexpectedError ¶
type UnexpectedError struct {
Err error
}
func NewUnexpectedError ¶
func NewUnexpectedError(err error) *UnexpectedError
func (*UnexpectedError) Error ¶
func (e *UnexpectedError) Error() string
