Method Detail

run

public void run()

Send ValidationRequest to replica

Specified by:

run in interface java.lang.Runnable

treesReceived

public void treesReceived(MerkleTrees trees)

Receive MerkleTrees from replica node.

Parameters:

trees - MerkleTrees that is sent from replica. Null if validation failed on replica node.

abort

public void abort()

Release any trees already received by this task, and place it a state where any trees received subsequently will be properly discarded.

isActive

public boolean isActive()
