                 throws InvalidDataException
```
    从接口复制的说明: IExtension

    指定者:
    
    decodeFrame 在接口中 IExtension
    
    参数:
    
    inputFrame - the frame, which has do be decoded to be used in the application
    
    抛出:
    
    InvalidDataException - Throw InvalidDataException if the received frame is not correctly implemented by the other endpoint or there are other protocol errors/decoding errors
  - encodeFrame
```
public void encodeFrame(Framedata inputFrame)
```
    从接口复制的说明: IExtension
    
    Encode a frame with a extension specific algorithm. The algorithm is subject to be implemented by the specific extension. The resulting frame will be send to the other endpoint.
    
    指定者:
    
    encodeFrame 在接口中 IExtension
    
    参数:
    
    inputFrame - the frame, which has do be encoded to be used on the other endpoint
  - acceptProvidedExtensionAsServer
```
public boolean acceptProvidedExtensionAsServer(String inputExtension)
```
    从接口复制的说明: IExtension
    
    Check if the received Sec-WebSocket-Extensions header field contains a offer for the specific extension if the endpoint is in the role of a server
    
    指定者:
    
    acceptProvidedExtensionAsServer 在接口中 IExtension
    
    参数:
    
    inputExtension - the received Sec-WebSocket-Extensions header field offered by the other endpoint
    
    返回:
    
    true, if the offer does fit to this specific extension
  - acceptProvidedExtensionAsClient
```
public boolean acceptProvidedExtensionAsClient(String inputExtension)
```
    从接口复制的说明: IExtension
    
    Check if the received Sec-WebSocket-Extensions header field contains a offer for the specific extension if the endpoint is in the role of a client
    
    指定者:
    
    acceptProvidedExtensionAsClient 在接口中 IExtension
    
    参数:
    
    inputExtension - the received Sec-WebSocket-Extensions header field offered by the other endpoint
    
    返回:
    
    true, if the offer does fit to this specific extension
  - isFrameValid
```
public void isFrameValid(Framedata inputFrame)
                  throws InvalidDataException
```
    从接口复制的说明: IExtension
    
    Check if the received frame is correctly implemented by the other endpoint and there are no specification errors (like wrongly set RSV)
    
    指定者:
    
    isFrameValid 在接口中 IExtension
    
    参数:
    
    inputFrame - the received frame
    
    抛出:
    
    InvalidDataException - Throw InvalidDataException if the received frame is not correctly implementing the specification for the specific extension
  - getProvidedExtensionAsClient
```
public String getProvidedExtensionAsClient()
```
    从接口复制的说明: IExtension
    
    Return the specific Sec-WebSocket-Extensions header offer for this extension if the endpoint is in the role of a client. If the extension returns an empty string (""), the offer will not be included in the handshake.
    
    指定者:
    
    getProvidedExtensionAsClient 在接口中 IExtension
    
    返回:
    
    the specific Sec-WebSocket-Extensions header for this extension
  - getProvidedExtensionAsServer
```
public String getProvidedExtensionAsServer()
```
    从接口复制的说明: IExtension
    
    Return the specific Sec-WebSocket-Extensions header offer for this extension if the endpoint is in the role of a server. If the extension returns an empty string (""), the offer will not be included in the handshake.
    
    指定者:
    
    getProvidedExtensionAsServer 在接口中 IExtension
    
    返回:
    
    the specific Sec-WebSocket-Extensions header for this extension
  - copyInstance
```
public IExtension copyInstance()
```
    从接口复制的说明: IExtension
    
    Extensions must only be by one websocket at all. To prevent extensions to be used more than once the Websocket implementation should call this method in order to create a new usable version of a given extension instance.
    The copy can be safely used in conjunction with a new websocket connection.
    
    指定者:
    
    copyInstance 在接口中 IExtension
    
    返回:
    
    a copy of the extension
  - reset
```
public void reset()
```
    从接口复制的说明: IExtension
    
    Cleaning up internal stats when the draft gets reset.
    
    指定者:
    
    reset 在接口中 IExtension
  - toString
```
public String toString()
```
    从接口复制的说明: IExtension
    
    Return a string which should contain the class name as well as additional information about the current configurations for this extension (DEBUG purposes)
    
    指定者:
    
    toString 在接口中 IExtension
    
    覆盖:
    
    toString 在类中 Object
    
    返回:
    
    a string containing the class name as well as additional information
  - hashCode
```
public int hashCode()

    覆盖:
    
    hashCode 在类中 Object
  - equals
```
public boolean equals(Object o)
```
    覆盖:
    
    equals 在类中 Object
