AsyncContextCallback (Apache Tomcat 10.0.27 API Documentation)

All Known Implementing Classes:

AsyncContextImpl
```
public interface AsyncContextCallback
```
Provides a mechanism for the Coyote connectors to communicate with the AsyncContext. It is implemented in this manner so that the org.apache.coyote package does not have a dependency on the org.apache.catalina package.

Method Summary

All Methods Instance Methods Abstract Methods
Modifier and Type	Method	Description
`void`	`decrementInProgressAsyncCount()`	Used to notify the Context that async processing has ended.
`void`	`fireOnComplete()`
`void`	`incrementInProgressAsyncCount()`	Used to notify the Context that async processing has started.
`boolean`	`isAvailable()`	Reports if the web application associated with this async request is available.

- Method Detail
  - fireOnComplete
```
void fireOnComplete()
```
  - isAvailable
```
boolean isAvailable()
```
    Reports if the web application associated with this async request is available.
    
    Returns:
    
    true if the associated web application is available, otherwise false
  - incrementInProgressAsyncCount
```
void incrementInProgressAsyncCount()
```
    Used to notify the Context that async processing has started. Specifically, for the counting of in-progress async requests to work correctly, this must be called exactly once every time the AsyncStateMachine transitions from DISPATCHED to any other state.
  - decrementInProgressAsyncCount
```
void decrementInProgressAsyncCount()
```
    Used to notify the Context that async processing has ended. Specifically, for the counting of in-progress async requests to work correctly, this must be called exactly once every time the AsyncStateMachine transitions to DISPATCHED from any other state.
