shouldContinue

public boolean shouldContinue()

shouldContinue is called by the underlying iterator WriteBatch.iterate(Handler). If it returns false, iteration is halted. Otherwise, it continues iterating. The default implementation always returns true.

返回:

boolean value indicating if the iteration is halted.
