Method Detail

read

public Event read()
           throws java.io.IOException

Description copied from interface: ObjectStream

Overrides:

read in class AbstractObjectStream<Event>

Returns:

the next object or null to signal that the stream is exhausted

Throws:

java.io.IOException - if there is an error during reading

calculateHashSum

public java.math.BigInteger calculateHashSum()

Calculates the hash sum of the stream. The method must be called after the stream is completely consumed.

Returns:

the hash sum

Throws:

java.lang.IllegalStateException - if the stream is not consumed completely, completely means that hasNext() returns false

remove
