MutableObjectId
public MutableObjectId()Empty constructor. Initialize object with default (zeros) value. -
MutableObjectId
MutableObjectId(MutableObjectId src) Copying constructor.- Parameters:
src- original entry, to copy id from
-
-
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.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-indexis less than 0, equal toConstants.OBJECT_ID_LENGTH, or greater thanConstants.OBJECT_ID_LENGTH.
-
set
private static int set(int w, int index, int value) -
clear
public void clear()Make this id matchObjectId.zeroId(). -
fromObjectId
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
Convert an ObjectId from hex characters.- Parameters:
str- the string to read from. Must be 40 characters long.
-
fromHexString
private void fromHexString(byte[] bs, int p) -
toObjectId
Obtain an immutable copy of this current object name value.See
AnyObjectId.copy()ifthisis a possibly subclassed (but immutable) identity and the application needs a lightweight identity only reference.- Specified by:
toObjectIdin classAnyObjectId- Returns:
- an immutable copy. May be
thisif this is already an immutable instance.
