Method Detail

apply

public V apply(InvocationContext<V> ctx)
        throws Exception

Description copied from interface: FaultToleranceStrategy

Apply the fault tolerance strategy around the target Callable. The Callable is wrapped in an InvocationContext.

Specified by:

apply in interface FaultToleranceStrategy<V>

Parameters:

ctx - the InvocationContext wrapping the Callable guarded by this fault tolerance strategy

Returns:

result computed by the target Callable

Throws:

Exception - if result couldn't be computed

addListener

public void addListener(CircuitBreakerListener listener)
