close

public void close()

Description copied from class: ConsumerLease

Abstract method that is intended to be extended by the pool that created this ConsumerLease object. It should ensure that the session given to create this session is rolled back and that the underlying kafka consumer is either returned to the pool for continued use or destroyed if this lease has been poisoned. It can only be called once. Calling it more than once can result in undefined and non threadsafe behavior.

Specified by:

close in interface Closeable

Specified by:

close in interface AutoCloseable

Overrides:

close

public void close(boolean forceClose)
