public abstract interface Checksum

Checksum is an interface that all data checksum objects (such as Adler32 and CRC32) should implement.

Method Summary

long	getValue() Returns the current value of the checksum
void	reset() Resets the checksum to the initial value
void	update(byte[] b, int offset, int length) Updates the checksum with the data in the given array
void	update(int b) Updates the checksum with the given byte

Method Detail

getValue

public long getValue()

Returns the current value of the checksum

update

public void update(int b)

Updates the checksum with the given byte

Parameters:

b - the byte of data to update the checksum with

update

public void update(byte[] b,
                   int offset,
                   int length)

Updates the checksum with the data in the given array

Parameters:

b - the array containing the data

offset - the index of the first byte of data

length - the number of data bytes in the array

reset
