public interface Checksum

java.util.zip.Checksum

Known indirect subclasses

Adler32	A class that can be used to compute the Adler-32 checksum of a data stream.
CRC32	A class that can be used to compute the CRC-32 of a data stream.

An interface representing a data checksum.

Public methods
`abstract long`	`getValue()` Returns the current checksum value.
`abstract void`	`reset()` Resets the checksum to its initial value.
`abstract void`	`update(byte[] b, int off, int len)` Updates the current checksum with the specified array of bytes.
`abstract void`	`update(int b)` Updates the current checksum with the specified byte.

public abstract long getValue ()

Returns the current checksum value.

Returns
`long`	the current checksum value

public abstract void reset ()

Resets the checksum to its initial value.

public abstract void update (byte[] b, 
                int off, 
                int len)

Updates the current checksum with the specified array of bytes.

Parameters
`b`	`byte`: the byte array to update the checksum with
`off`	`int`: the start offset of the data
`len`	`int`: the number of bytes to use for the update

public abstract void update (int b)

Updates the current checksum with the specified byte.

Parameters
`b`	`int`: the byte to update the checksum with
