- Method Detail
  - discoverSupportedHeaders
```
AsyncResult<List<String>> discoverSupportedHeaders(Jid jid)
```
    Discovers the supported headers of another entity.
    
    Parameters:
    
    jid - The JID.
    
    Returns:
    
    The async result with the list of supported headers.
  - getSupportedHeaders
```
Set<String> getSupportedHeaders()
```
    Gets the supported headers as unmodifiable set.
    If you want to advertise support for a specific header, add it to this set. Service discovery requests to the 'header' node will then reveal supported headers.
    
    Returns:
    
    The supported headers.
  - addSupportedHeader
```
boolean addSupportedHeader(String header)
```
    Adds a supported header. Adding a header automatically includes this protocol in service discovery responses.
    
    Parameters:
    
    header - The header.
    
    Returns:
    
    True, if the header was added.

    removeSupportedHeader(String)
  - removeSupportedHeader
```
boolean removeSupportedHeader(String header)
```
    Removes a supported header. If there are no headers left, this protocol is no longer included in service discovery responses.
    
    Parameters:
    
    header - The header.
    
    Returns:
    
    True, if the header was removed.
