java.lang.Object
org.eclipse.jgit.lfs.lib.AnyLongObjectId
org.eclipse.jgit.lfs.lib.MutableLongObjectId
All Implemented Interfaces:

Since:
4.3

  • Constructor Details

    • MutableLongObjectId

      public MutableLongObjectId()
      Empty constructor. Initialize object with default (zeros) value.

  • Method Details

    • setByte

      public void setByte(int index, int value)
      Set any byte in the id.
      Parameters:
      index - index of the byte to set in the raw form of the ObjectId. Must be in range [0, Constants.LONG_OBJECT_ID_LENGTH).
      value - the value of the specified byte at index. Values are unsigned and thus are in the range [0,255] rather than the signed byte range of [-128, 127].
      Throws:
      ArrayIndexOutOfBoundsException - index is less than 0, equal to Constants.LONG_OBJECT_ID_LENGTH, or greater than Constants.LONG_OBJECT_ID_LENGTH.

    • clear

      public void clear()
      Make this id match LongObjectId.zeroId().

    • fromObjectId

      public void fromObjectId(AnyLongObjectId src)
      Copy a LongObjectId into this mutable buffer.
      Parameters:
      src - the source id to copy from.

    • fromRaw

      public void fromRaw(byte[] bs)
      Convert a LongObjectId from raw binary representation.
      Parameters:
      bs - the raw byte buffer to read from. At least 32 bytes must be available within this byte array.

    • fromRaw

      public void fromRaw(byte[] bs, int p)
      Convert a LongObjectId from raw binary representation.
      Parameters:
      bs - the raw byte buffer to read from. At least 32 bytes after p must be available within this byte array.
      p - position to read the first byte of data from.

    • fromRaw

      public void fromRaw(long[] longs)
      Convert a LongObjectId from binary representation expressed in integers.
      Parameters:
      longs - the raw long buffer to read from. At least 4 longs must be available within this longs array.

    • fromRaw

      public void fromRaw(long[] longs, int p)
      Convert a LongObjectId from binary representation expressed in longs.
      Parameters:
      longs - the raw int buffer to read from. At least 4 longs after p must be available within this longs array.
      p - position to read the first integer of data from.

    • fromString

      public void fromString(byte[] buf, int offset)
      Convert a LongObjectId from hex characters (US-ASCII).
      Parameters:
      buf - the US-ASCII buffer to read from. At least 32 bytes after offset must be available within this byte array.
      offset - position to read the first character from.

    • fromString

      public void fromString(String str)
      Convert a LongObjectId from hex characters.
      Parameters:
      str - the string to read from. Must be 64 characters long.

    • toObjectId

      public LongObjectId toObjectId()
      Obtain an immutable copy of this current object.

      See AnyLongObjectId.copy() if this is a possibly subclassed (but immutable) identity and the application needs a lightweight identity only reference.

      Specified by:
      toObjectId in class AnyLongObjectId
      Returns:
      an immutable copy. May be this if this is already an immutable instance.
