Interface Management

public interface Management

Management class manages the underlying Association and Server.

Management should persist the state of Server and Association

Management when started looks for file XXX_sctp.xml containing serialized state of underlying Association and Server. Set the directory path by calling setPersistDir(String) to direct Management to look at specified directory for underlying serialized file.

If directory path is not set, Management searches for system property sctp.persist.dir to get the path for directory

Even if sctp.persist.dir system property is not set, Management will look at System set property user.dir

Returns:

setOptionSoRcvbuf

void setOptionSoRcvbuf(Integer optionSoRcvbuf)

SCTP option: The size of the socket receive buffer.

Parameters:

optionSoRcvbuf -

getOptionSoLinger

Integer getOptionSoLinger()

SCTP option: Linger on close if data is present. The value of this socket option is an Integer that controls the action taken when unsent data is queued on the socket and a method to close the socket is invoked. If the value of the socket option is zero or greater, then it represents a timeout value, in seconds, known as the linger interval. The linger interval is the timeout for the close method to block while the operating system attempts to transmit the unsent data or it decides that it is unable to transmit the data. If the value of the socket option is less than zero then the option is disabled. In that case the close method does not wait until unsent data is transmitted; if possible the operating system will transmit any unsent data before the connection is closed.

Returns:

setOptionSoLinger

void setOptionSoLinger(Integer optionSoLinger)
