Increment the error count for this service.

getAsyncCount

public int getAsyncCount()

Get the number of times this service was invoked asynchronously

incrementAsyncCount

public void incrementAsyncCount()

Increment the async count for this service.

getAsyncErrorCount

                                throws IllegalArgumentException

Set the number of suspended async requests for this service.

Throws:

IllegalArgumentException

incrementParkedAsyncRequestCount

public void incrementParkedAsyncRequestCount(int delta)
