currentState

public Object[] currentState()

Description copied from interface: Snapshotable

Used to collect the serializable state of the processing element, that need to be persisted for the reconstructing the element to the same state on a different point of time

Specified by:

currentState in interface Snapshotable

Returns:

stateful objects of the processing element as an array

restoreState

public void restoreState(Object[] state)

Description copied from interface: Snapshotable

Used to restore serialized state of the processing element, for reconstructing the element to the same state as if was on a previous point of time.

Specified by:

restoreState in interface Snapshotable

Parameters:

state - the stateful objects of the element as an array on the same order provided by currentState().

getElementId

public String getElementId()

Specified by:

getElementId in interface Snapshotable
