| Execute the given command. This method is guaranteed
only to arrange for execution, that may actually
occur sometime later; for example in a new
thread. However, in fully generic use, callers
should be prepared for execution to occur in
any fashion at all, including immediate direct
execution.
The method is defined not to throw
any checked exceptions during execution of the command. Generally,
any problems encountered will be asynchronous and
so must be dealt with via callbacks or error handler
objects. If necessary, any context-dependent
catastrophic errors encountered during
actions that arrange for execution could be accompanied
by throwing context-dependent unchecked exceptions.
However, the method does throw InterruptedException:
It will fail to arrange for execution
if the current thread is currently interrupted.
Further, the general contract of the method is to avoid,
suppress, or abort execution if interruption is detected
in any controllable context surrounding execution.
