Method Detail

run

public void run()
         throws RuntimeException

This method actually obtains the current sequence value.

Specified by:

run in interface Runnable

Throws:

RuntimeException - any SQLExceptions that occur when obtaining the sequence value are wrapped in a runtime exception to avoid breaking the Runnable method signature. The caller can obtain the "real" exception by calling getCause().
