NetworkConfig

public NetworkConfig()

Method Detail

getPort

public int getPort()

Returns the port the Hazelcast member will try to bind on. A port number of 0 will let the system pick up an ephemeral port.

Returns:

the port the Hazelcast member will try to bind on

See Also:

setPort(int)

setPort

public NetworkConfig setPort(int port)

Sets the port the Hazelcast member will try to bind on. A valid port value is between 0 and 65535. A port number of 0 will let the system pick up an ephemeral port.

Parameters:

port - the port the Hazelcast member will try to bind on

Returns:

NetworkConfig the updated NetworkConfig

See Also:

getPort(), for more information

getPortCount

public int getPortCount()

Returns the maximum number of ports allowed to try to bind on.

Returns:

the maximum number of ports allowed to try to bind on

See Also:

setPortCount(int), for more information

setPortCount

public void setPortCount(int portCount)

The maximum number of ports allowed to use.

Parameters:

portCount - the maximum number of ports allowed to use

See Also:

for more information

isPortAutoIncrement

public boolean isPortAutoIncrement()

Checks if a Hazelcast member is allowed find a free port by incrementing the port number when it encounters an occupied port.

Returns:

the portAutoIncrement

See Also:

setPortAutoIncrement(boolean)

setPortAutoIncrement

public NetworkConfig setPortAutoIncrement(boolean portAutoIncrement)

Sets if a Hazelcast member is allowed to find a free port by incrementing the port number when it encounters an occupied port.

If you explicitly want to control the port a Hazelcast member is going to use, you probably want to set portAutoincrement to false. In this case, the Hazelcast member is going to try the port setPort(int) and if the port is not free, the member will not start and throw an exception.

If this value is set to true, Hazelcast will start at the port specified by setPort(int) and will try until it finds a free port, or until it runs out of ports to try setPortCount(int).

Parameters:

portAutoIncrement - the portAutoIncrement to set

Returns:

the updated NetworkConfig

See Also:

isPortAutoIncrement(), setPortCount(int), setPort(int)

isReuseAddress

public boolean isReuseAddress()

setReuseAddress

public NetworkConfig setReuseAddress(boolean reuseAddress)

Sets the reuse address.

When should setReuseAddress(true) be used?

When the member is shutdown, the server socket port will be in TIME_WAIT state for the next 2 minutes or so. If you start the member right after shutting it down, you may not be able to bind to the same port because it is in TIME_WAIT state. if you set reuseAddress=true then TIME_WAIT will be ignored and you will be able to bind to the same port again.

This property should not be set to true on the Windows platform: see

1. http://bugs.sun.com/bugdatabase/view_bug.do?bug_id=6421091
2. http://www.hsc.fr/ressources/articles/win_net_srv/multiple_bindings.html

By default, if the OS is Windows then reuseAddress will be false.

getOutboundPortDefinitions

public Collection<String> getOutboundPortDefinitions()

setOutboundPortDefinitions

public NetworkConfig setOutboundPortDefinitions(Collection<String> outboundPortDefs)

addOutboundPortDefinition

public NetworkConfig addOutboundPortDefinition(String portDef)

getOutboundPorts

public Collection<Integer> getOutboundPorts()

setOutboundPorts

public NetworkConfig setOutboundPorts(Collection<Integer> outboundPorts)

addOutboundPort

public NetworkConfig addOutboundPort(int port)

getInterfaces

public InterfacesConfig getInterfaces()

Returns:

the interfaces

setInterfaces

public NetworkConfig setInterfaces(InterfacesConfig interfaces)

Parameters:

interfaces - the interfaces to set

getJoin

public JoinConfig getJoin()

Returns the JoinConfig.

Returns:

the join

setJoin

public NetworkConfig setJoin(JoinConfig join)

Parameters:

join - the join to set

getPublicAddress

public String getPublicAddress()

setPublicAddress

public NetworkConfig setPublicAddress(String publicAddress)

Overrides the public address of a member. Behind a NAT, two endpoints may not be able to see/access each other. If both nodes set their public addresses to their defined addresses on NAT, then that way they can communicate with each other. It should be set in the format “host IP address:port number”.

getSocketInterceptorConfig

public SocketInterceptorConfig getSocketInterceptorConfig()

Gets the SocketInterceptorConfig. The value can be null if no socket interception is needed.

Returns:

the SocketInterceptorConfig

See Also:

setSocketInterceptorConfig(SocketInterceptorConfig)

setSocketInterceptorConfig

public NetworkConfig setSocketInterceptorConfig(SocketInterceptorConfig socketInterceptorConfig)

Sets the SocketInterceptorConfig. The value can be null if no socket interception is needed.

Parameters:

socketInterceptorConfig - the SocketInterceptorConfig to set

Returns:

the updated NetworkConfig

getSymmetricEncryptionConfig

public SymmetricEncryptionConfig getSymmetricEncryptionConfig()

Gets the SymmetricEncryptionConfig. The value can be null which means that no symmetric encryption should be used.

Returns:

the SymmetricEncryptionConfig

setSymmetricEncryptionConfig

public NetworkConfig setSymmetricEncryptionConfig(SymmetricEncryptionConfig symmetricEncryptionConfig)

Sets the SymmetricEncryptionConfig. The value can be null if no symmetric encryption should be used.

Parameters:

symmetricEncryptionConfig - the SymmetricEncryptionConfig to set

Returns:

the updated NetworkConfig

See Also:

getSymmetricEncryptionConfig()

getSSLConfig

public SSLConfig getSSLConfig()

Returns the current SSLConfig. It is possible that null is returned if no SSLConfig has been set.

Returns:

the SSLConfig

See Also:

setSSLConfig(SSLConfig)

setSSLConfig

public NetworkConfig setSSLConfig(SSLConfig sslConfig)

Sets the SSLConfig. null value indicates that no SSLConfig should be used.

Parameters:

sslConfig - the SSLConfig

Returns:

the updated NetworkConfig

See Also:

getSSLConfig()

getMemberAddressProviderConfig

public MemberAddressProviderConfig getMemberAddressProviderConfig()

setMemberAddressProviderConfig

public NetworkConfig setMemberAddressProviderConfig(MemberAddressProviderConfig memberAddressProviderConfig)

setIcmpFailureDetectorConfig

public NetworkConfig setIcmpFailureDetectorConfig(IcmpFailureDetectorConfig icmpFailureDetectorConfig)

Sets the IcmpFailureDetectorConfig. The value can be null if this detector isn't needed.

Parameters:

icmpFailureDetectorConfig - the IcmpFailureDetectorConfig to set

Returns:

the updated NetworkConfig

See Also:

getIcmpFailureDetectorConfig()

getIcmpFailureDetectorConfig

Returns the current IcmpFailureDetectorConfig. It is possible that null is returned if no IcmpFailureDetectorConfig has been set.

Returns:

the IcmpFailureDetectorConfig

See Also:

setIcmpFailureDetectorConfig(IcmpFailureDetectorConfig)

toString
