Method Detail

getName

public String getName()

Return the name of the component

Returns:

the name

getChecksum

public abstract byte[] getChecksum()

Return the checksum of the component. The checksum is an aribitrary byte array. It is up the component implementing this class to determine what a sensible checksum consists of.

Returns:

the component's checksum as a byte array

compareChecksum

public boolean compareChecksum(byte[] otherChecksum)

compare the current checksum with another one.

Parameters:

otherChecksum - checksum to compare

Returns:

false if they aren't the same, true if they are

makeListOfBytes

public static List makeListOfBytes(byte[] b)

toString

public String toString()

Overrides:

toString in class Object

Returns:

a human readable version of this checksum
