Constructor Detail

MutableLongObjectId

public MutableLongObjectId()

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

Method Detail

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.
