| 10 |  |  |  |  |  |  | Net::WebSocket::PMCE::Data - Base class for PMCE data modules. | 
| 11 |  |  |  |  |  |  |  | 
| 12 |  |  |  |  |  |  | =head1 DESCRIPTION | 
| 13 |  |  |  |  |  |  |  | 
| 14 |  |  |  |  |  |  | =head1 METHODS | 
| 15 |  |  |  |  |  |  |  | 
| 16 |  |  |  |  |  |  | Available on all instances: | 
| 17 |  |  |  |  |  |  |  | 
| 18 |  |  |  |  |  |  | =head2 I->message_is_compressed( MESSAGE ) | 
| 19 |  |  |  |  |  |  |  | 
| 20 |  |  |  |  |  |  | MESSAGE is an instance of L. | 
| 21 |  |  |  |  |  |  | The output is a Perl boolean that indicates whether the message | 
| 22 |  |  |  |  |  |  | appears to be PMCE-compressed. | 
| 23 |  |  |  |  |  |  |  | 
| 24 |  |  |  |  |  |  | You can also call this as a class method, e.g.: | 
| 25 |  |  |  |  |  |  |  | 
| 26 |  |  |  |  |  |  | Net::WebSocket::PMCE->message_is_compressed( $message_obj ); |

| 32 |  |  |  |  |  |  | } | 
| 33 |  |  |  |  |  |  |  | 
| 34 |  |  |  |  |  |  | =head2 INITIAL_FRAME_RSV() | 
| 35 |  |  |  |  |  |  |  | 
| 36 |  |  |  |  |  |  | Returns the numeric value of the RSV bits for PMCEs, | 
| 37 |  |  |  |  |  |  | suitable for giving to a L subclass’s | 
| 38 |  |  |  |  |  |  | constructor. |
