Method Detail

getName

public java.lang.String getName()

Return the name of the component

Returns:

the name

getChecksum

public abstract byte[] getChecksum()

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
