Class AsyncContext<T>

java.lang.Object

com.vmware.vapi.bindings.server.AsyncContext<T>

public abstract class AsyncContext<T>
extends Object

Context of an asynchronous operation. Combines useful information about the operation (see getInvocationContext()) with means to complete the operation (with a result or an error) or report progress.

This context is the only legal way to complete an operation invocation (with a result object or an error) or report progress. The invocation will hang until either setResult(Object) or setError(RuntimeException) marks the operation as complete. Completing the operation more than once is forbidden. Reporting progress after the operation is complete is forbidden.
