- 
getPollerDeprecated.
- 
getSendfileDeprecated.
- 
getLocalAddressDeprecated.Description copied from class:AbstractEndpointObtain the network address the server socket is bound to. This primarily exists to enable the correct address to be used when unlocking the server socket since it removes the guess-work involved if no address is specifically set.- Specified by:
- getLocalAddressin class- AbstractEndpoint<Long,- Long> 
- Returns:
- The network address that the server socket is listening on or null if the server socket is not currently bound.
- Throws:
- IOException- If there is a problem determining the currently bound socket
 
- 
setMaxConnectionspublic void setMaxConnections(int maxConnections) Deprecated.This endpoint does not support-1for unlimited connections, nor does it support setting this attribute while the endpoint is running.- Overrides:

- 
getKeepAliveCountpublic int getKeepAliveCount()Deprecated.Obtain the number of kept alive sockets.- Returns:
- The number of open sockets currently managed by the Poller
 
- 
getSendfileCountpublic int getSendfileCount()Deprecated.Obtain the number of sendfile sockets.- Returns:
- The number of sockets currently managed by the Sendfile poller.
 
- 
getIdDeprecated.Description copied from class:AbstractEndpointThe default behavior is to identify connectors uniquely with address and port. However, certain connectors are not using that and need some other identifier, which then can be used as a replacement.- Overrides:
- getIdin class- AbstractEndpoint<Long,- Long> 
- Returns:
- the id
 
- 
bindDeprecated.Initialize the endpoint.- Specified by:
- bindin class- AbstractEndpoint<Long,- Long>

- Throws:
- Exception- If the SSLContext cannot be created for the given SSLHostConfig
 
- 
getSslContextDeprecated.Description copied from interface:SSLContext.SNICallBackThis callback is made during the TLS handshake when the client uses the SNI extension to request a specific TLS host.- Specified by:
- getSslContextin interface- SSLContext.SNICallBack
- Parameters:
- sniHostName- The host name requested by the client - must be in lower case
- Returns:
- The Java representation of the pointer to the OpenSSL SSLContext to use for the given host or zero if no SSLContext could be identified
 
-

- setDefaultSslHostConfigin class- AbstractEndpoint<Long,- Long>
