Methods
Modifier and Type	Method and Description
`AsyncSupport`	`defaultCometSupport(boolean preferBlocking)` This method is used to determine the default AsyncSupport if all else fails
`java.util.List<java.lang.Class<? extends AsyncSupport>>`	`detectContainersPresent()` Returns a list of comet support by containers available on the classpath
`java.util.List<java.lang.Class<? extends AsyncSupport>>`	`detectServlet3WebSocketPresent()`
`java.util.List<java.lang.Class<? extends AsyncSupport>>`	`detectWebSocketPresent(boolean useNativeIfPossible)`
`AsyncSupport`	`newCometSupport(java.lang.Class<? extends AsyncSupport> targetClass)` Given a Class of something that extends AsyncSupport, it tries to return an instance of that class The class has to have a visible constructor with the signature (@link {AtmosphereConfig})
`AsyncSupport`	`newCometSupport(java.lang.String targetClassFQN)`
`AsyncSupport`	`resolve(boolean useNativeIfPossible, boolean defaultToBlocking)` This method is the general interface to the outside world
`AsyncSupport`	`resolve(boolean useNativeIfPossible, boolean defaultToBlocking, boolean useWebsocketIfPossible)`
`protected AsyncSupport`	`resolveMultipleNativeSupportConflict(java.util.List<java.lang.Class<? extends AsyncSupport>> available)` This method is called if there are more than one potential native container in scope
`protected AsyncSupport`	`resolveNativeCometSupport(java.util.List<java.lang.Class<? extends AsyncSupport>> available)` This method is called to determine which native comet support to the used
`AsyncSupport`	`resolveWebSocket(java.util.List<java.lang.Class<? extends AsyncSupport>> available)`
`protected boolean`	`testClassExists(java.lang.String testClass)` Convenience method that tests if a class with the given FQN is present on the classpath

    Convenience method that tests if a class with the given FQN is present on the classpath
    
    Parameters:
    testClass -
    
    Returns:
    true if the class is present
  - detectContainersPresent
```
public java.util.List<java.lang.Class<? extends AsyncSupport>> detectContainersPresent()
```
    Returns a list of comet support by containers available on the classpath
    
    Returns:
  - detectWebSocketPresent
```
public java.util.List<java.lang.Class<? extends AsyncSupport>> detectWebSocketPresent(boolean useNativeIfPossible)

```
  - defaultCometSupport
```
public AsyncSupport defaultCometSupport(boolean preferBlocking)

    Returns:
  - newCometSupport
```
public AsyncSupport newCometSupport(java.lang.Class<? extends AsyncSupport> targetClass)

    Returns:
    an instance of AsyncSupport
  - resolve
```
public AsyncSupport resolve(boolean useNativeIfPossible,
                   boolean defaultToBlocking,

```
  - resolveNativeCometSupport
```
protected AsyncSupport resolveNativeCometSupport(java.util.List<java.lang.Class<? extends AsyncSupport>> available)
```
    This method is called to determine which native comet support to the used
    
    Parameters:
