Meteor (atmosphere-runtime 2.1.9 API)

java.lang.Object
- org.atmosphere.cpr.Meteor

```
public class Meteor
extends Object
```
A Meteor is a simple class that can be used from a Servlet to suspend, broadcast and resume responses. A Meteor can be created by invoking the build() method.
Meteor.build(HttpServletRequest).suspend(-1);
A Meteor is usually created when an application needs to suspend a response. A Meteor instance can then be cached and re-used later for either broadcasting a message, or when an application needs to resume the suspended response.

  - build
```
public static final Meteor build(javax.servlet.http.HttpServletRequest r,
           Serializer s)
```
    Create a Meteor using the HttpServletRequest and use the Serializer for writing the result of a broadcast operation using the HttpServletResponse.
    
    Parameters:
    r - an HttpServletRequest
    s - a Serializer used when writing broadcast events
    
    Returns:
    a Meteor than can be used to resume, suspend and broadcast Object
  - build
```
public static final Meteor build(javax.servlet.http.HttpServletRequest req,
           List<BroadcastFilter> l,
           Serializer s)
```
    Create a Meteor using the HttpServletRequest and use a list of BroadcastFilter and Serializer for writing the result of a broadcast operation the HttpServletResponse.
    
    Parameters:
    req - an HttpServletRequest
    l - a list of BroadcastFilter
    s - a Serializer used when writing broadcast events
    
    Returns:
    a Meteor than can be used to resume, suspend and broadcast Object
  - build
```
public static final Meteor build(javax.servlet.http.HttpServletRequest req,
           Broadcaster.SCOPE scope,
           List<BroadcastFilter> l,
           Serializer s)
```
    Create a Meteor using the HttpServletRequest and use a list of BroadcastFilter and Serializer for writing the result of a broadcast operation the HttpServletResponse.
    
    Parameters:
    req - an HttpServletRequest
    scope - the Broadcaster.SCOPE}
    l - a list of BroadcastFilter
    s - a Serializer used when writing broadcast events
    
    Returns:
    a Meteor than can be used to resume, suspend and broadcast Object
  - suspend
```
public Meteor suspend(long l)
```
    Suspend the underlying HttpServletResponse. Passing a value of -1 suspends the response forever.
