Checksum
public final class CRC32C extends Object implements Checksum
CRC-32C is defined in RFC 3720: Internet Small Computer Systems Interface (iSCSI).
Passing a null
argument to a method in this class will cause a NullPointerException
to be thrown.
Constructor | Description |
---|---|
CRC32C() |
Creates a new CRC32C object. |
Modifier and Type | Method | Description |
---|---|---|
long |
getValue() |
Returns CRC-32C value. |
void |
reset() |
Resets CRC-32C to initial value. |
void |
update |
Updates the CRC-32C checksum with the specified array of bytes. |
void |
update |
Updates the CRC-32C checksum with the specified byte (the low eight bits of the argument b). |
void |
update |
Updates the CRC-32C checksum with the bytes from the specified buffer. |

in interface Checksum
b
- the byte array to update the checksum withoff
- the start offset of the datalen
- the number of bytes to use for the updateArrayIndexOutOfBoundsException
- if off
is negative, or len
is negative, or off+len
is negative or greater than the length of the array b
