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.OBJECT_ID_LENGTH
).value
- the value of the specified byte atindex
. 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 toConstants.OBJECT_ID_LENGTH
, or greater thanConstants.OBJECT_ID_LENGTH
.
-
clear
public void clear()
Make this id matchObjectId.zeroId()
.
-
fromObjectId
public void fromObjectId(AnyObjectId src)
Copy an ObjectId into this mutable buffer.- Parameters:
src
- the source id to copy from.
-
fromRaw
public void fromRaw(byte[] bs)
Convert an ObjectId from raw binary representation.- Parameters:
bs
- the raw byte buffer to read from. At least 20 bytes must be available within this byte array.
-
fromRaw
public void fromRaw(byte[] bs, int p)
Convert an ObjectId from raw binary representation.- Parameters:
bs
- the raw byte buffer to read from. At least 20 bytes after p must be available within this byte array.p
- position to read the first byte of data from.
-
fromRaw
public void fromRaw(int[] ints)
Convert an ObjectId from binary representation expressed in integers.- Parameters:
ints
- the raw int buffer to read from. At least 5 integers must be available within this integers array.
-
fromRaw
public void fromRaw(int[] ints, int p)
Convert an ObjectId from binary representation expressed in integers.- Parameters:
ints
- the raw int buffer to read from. At least 5 integers after p must be available within this integers array.p
- position to read the first integer of data from.
-
set
public void set(int a, int b, int c, int d, int e)
Convert an ObjectId from binary representation expressed in integers.- Parameters:
a
- an int.b
- an int.c
- an int.d
- an int.e
- an int.- Since:
- 4.7
-
fromString
public void fromString(byte[] buf, int offset)
Convert an ObjectId from hex characters (US-ASCII).- Parameters:
buf
- the US-ASCII buffer to read from. At least 40 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 an ObjectId from hex characters.- Parameters:
str
- the string to read from. Must be 40 characters long.
-
toObjectId
public ObjectId toObjectId()
Obtain an immutable copy of this current object name value.See
AnyObjectId.copy()
ifthis
is a possibly subclassed (but immutable) identity and the application needs a lightweight identity only reference.- Specified by:
toObjectId
in classAnyObjectId
- Returns:
- an immutable copy. May be
this
if this is already an immutable instance.
