  - OBJECT_ID_LENGTH
```
public static final int OBJECT_ID_LENGTH

    This constant is fixed and is defined by the Git packfile format.
    
    See Also:
    
    TYPE_COMMIT, Constant Field Values
  - OBJ_TREE
```
public static final int OBJ_TREE
```
    In-pack object type: tree.
    Indicates the associated object is a tree.

    See Also:
    
    TYPE_BLOB, Constant Field Values
  - OBJ_BLOB

    Constant Field Values
  - OBJ_OFS_DELTA
```
public static final int OBJ_OFS_DELTA
```
    In-pack object type: offset delta
    Objects stored with this type actually have a different type which must be obtained from their delta base object. Delta objects store only the changes needed to apply to the base object in order to recover the original object.
    An offset delta uses a negative offset from the start of this object to refer to its delta base. The base object must exist in this packfile (even in the case of a thin pack).
    This constant is fixed and is defined by the Git packfile format.
    
    See Also:
    
    Constant Field Values
  - OBJ_REF_DELTA
```
public static final int OBJ_REF_DELTA
```
    In-pack object type: reference delta
    Objects stored with this type actually have a different type which must be obtained from their delta base object. Delta objects store only the changes needed to apply to the base object in order to recover the original object.
    A reference delta uses a full object id (hash) to reference the delta base. The base object is allowed to be omitted from the packfile, but only in the case of a thin pack being transferred over the network.
    This constant is fixed and is defined by the Git packfile format.
    
    See Also:
    
    Constant Field Values
  - PACK_SIGNATURE
```
public static final byte[] PACK_SIGNATURE
```
    Pack file signature that occurs at file header - identifies file as Git packfile formatted.
    This constant is fixed and is defined by the Git packfile format.

```
public static java.security.MessageDigest newMessageDigest()
```
    Create a new digest function for objects.
    
    Returns:
    
    a new digest object.
    
    Throws:
    
    java.lang.RuntimeException - this Java virtual machine does not support the required hash function. Very unlikely given that JGit uses a hash function that is in the Java reference specification.
  - typeString
```
public static java.lang.String typeString(int typeCode)
```
    Convert an OBJ_* type constant to a TYPE_* type constant.
    
    Parameters:
    
    typeCode - the type code, from a pack representation.
    
    Returns:
    
    the canonical string name of this type.
  - encodedTypeString
```
public static byte[] encodedTypeString(int typeCode)
```
    Convert an OBJ_* type constant to an ASCII encoded string constant.
    The ASCII encoded string is often the canonical representation of the type within a loose object header, or within a tag header.
    
    Parameters:
    
    typeCode - the type code, from a pack representation.
    
    Returns:
    
    the canonical ASCII encoded name of this type.
  - decodeTypeString
```
public static int decodeTypeString(AnyObjectId id,
                                   byte[] typeString,
                                   byte endMark,
                                   MutableInteger offset)
                            throws CorruptObjectException
```
    Parse an encoded type string into a type constant.
    
    Parameters:
    
    id - object id this type string came from; may be null if that is not known at the time the parse is occurring.
    
    typeString - string version of the type code.
    
    endMark - character immediately following the type string. Usually ' ' (space) or '\n' (line feed).
    
    offset - position within typeString where the parse should start. Updated with the new position (just past endMark when the parse is successful.
    
    Returns:
    
    a type code constant (one of OBJ_BLOB, OBJ_COMMIT, OBJ_TAG, OBJ_TREE.
    
    Throws:
    
    CorruptObjectException - there is no valid type identified by typeString.
  - encodeASCII
```
public static byte[] encodeASCII(long s)
```
    Convert an integer into its decimal representation.
    
    Parameters:
    
    s - the integer to convert.
    
    Returns:
    
    a decimal representation of the input integer. The returned array is the smallest array that will hold the value.
  - encodeASCII
```
public static byte[] encodeASCII(java.lang.String s)
```
    Convert a string to US-ASCII encoding.
    
    Parameters:
    
    s - the string to convert. Must not contain any characters over 127 (outside of 7-bit ASCII).
    
    Returns:
    
    a byte array of the same length as the input string, holding the same characters, in the same order.
    
    Throws:
    
    java.lang.IllegalArgumentException - the input string contains one or more characters outside of the 7-bit ASCII character space.
  - encode
```
public static byte[] encode(java.lang.String str)
```
    Convert a string to a byte array in the standard character encoding.
    
    Parameters:
    
    str - the string to convert. May contain any Unicode characters.
    
    Returns:
    
    a byte array representing the requested string, encoded using the default character encoding (UTF-8).
