Method Detail

addHeader

void addHeader(java.lang.String name,
               java.lang.String value)

Deprecated.

Add a header value to the response.

Parameters:

name - the header name

value - the header value

getAcceptedSubProtocol

java.lang.String getAcceptedSubProtocol()

Deprecated.

Get the accepted WebSocket protocol.

Returns:

the accepted WebSocket protocol.

getExtensions

java.util.List<ExtensionConfig> getExtensions()

Deprecated.

Get the list of extensions that should be used for the websocket.

Returns:

the list of negotiated extensions to use.

getHeader

java.lang.String getHeader(java.lang.String name)

Deprecated.

Get a header value

Parameters:

name - the header name

Returns:

the value (null if header doesn't exist)

getHeaderNames

java.util.Set<java.lang.String> getHeaderNames()

Deprecated.

Get the header names

Returns:

the set of header names

getHeaders

java.util.Map<java.lang.String,java.util.List<java.lang.String>> getHeaders()

Deprecated.

Get the headers map

Returns:

the map of headers

getHeaders

java.util.List<java.lang.String> getHeaders(java.lang.String name)

Deprecated.

Get the multi-value header value

Parameters:

name - the header name

Returns:

the list of values (null if header doesn't exist)

getStatusCode

int getStatusCode()

Deprecated.

Get the HTTP Response Status Code

Returns:

the status code

getStatusReason

java.lang.String getStatusReason()

Deprecated.

Get the HTTP Response Status Reason

Returns:

the HTTP Response status reason

isSuccess

@Deprecated
boolean isSuccess()

Deprecated.

this has no replacement, will be removed in Jetty 10

Test if upgrade response is successful.

Merely notes if the response was sent as a WebSocket Upgrade, or was failed (resulting in no upgrade handshake)

Returns:

true if upgrade response was generated, false if no upgrade response was generated

sendForbidden

void sendForbidden(java.lang.String message)
            throws java.io.IOException

Deprecated.

Issue a forbidden upgrade response.

This means that the websocket endpoint was valid, but the conditions to use a WebSocket resulted in a forbidden access.

Use this when the origin or authentication is invalid.

Parameters:

message - the short 1 line detail message about the forbidden response

Throws:

java.io.IOException - if unable to send the forbidden

setAcceptedSubProtocol

void setAcceptedSubProtocol(java.lang.String protocol)

Deprecated.

Set the accepted WebSocket Protocol.

Parameters:

protocol - the protocol to list as accepted

setExtensions

void setExtensions(java.util.List<ExtensionConfig> extensions)

Deprecated.

Set the list of extensions that are approved for use with this websocket.

Notes:

• Per the spec you cannot add extensions that have not been seen in the UpgradeRequest, just remove entries you don't want to use
• If this is unused, or a null is passed, then the list negotiation will follow default behavior and use the complete list of extensions that are available in this WebSocket server implementation.

Parameters:

extensions - the list of extensions to use.

setHeader

void setHeader(java.lang.String name,
               java.lang.String value)

Deprecated.

Set a header

Overrides previous value of header (if set)

Parameters:

name - the header name

value - the header value

setStatusCode

void setStatusCode(int statusCode)

Deprecated.

Set the HTTP Response status code

Parameters:

statusCode - the status code

setStatusReason

void setStatusReason(java.lang.String statusReason)

Deprecated.

Set the HTTP Response status reason phrase

Note, not all implementation of UpgradeResponse can support this feature

Parameters:

statusReason - the status reason phrase

setSuccess

@Deprecated
void setSuccess(boolean success)

Deprecated.

this has no replacement, will be removed in Jetty 10

Set the success of the upgrade response.

Parameters:

success - true to indicate a response to the upgrade handshake was sent, false to indicate no upgrade response was sent
