Method Detail

onSpiContextInitialized

public void onSpiContextInitialized(GridSpiContext spiCtx)
                             throws GridSpiException

Callback invoked when SPI context is initialized after GridTcpDiscoverySpi.spiStart(String) method is completed, SPI context can be stored for future access.

Specified by:

onSpiContextInitialized in interface GridTcpDiscoveryIpFinder

Parameters:

spiCtx - Spi context.

Throws:

GridSpiException - In case of error.

onSpiContextDestroyed

public void onSpiContextDestroyed()

Callback invoked prior to stopping grid before SPI context is destroyed. Note that invoking SPI context after this callback is complete is considered illegal and may produce unknown results.

Specified by:

onSpiContextDestroyed in interface GridTcpDiscoveryIpFinder

initializeLocalAddresses

public void initializeLocalAddresses(Collection<InetSocketAddress> addrs)
                              throws GridSpiException

Initializes addresses discovery SPI binds to.

Specified by:

initializeLocalAddresses in interface GridTcpDiscoveryIpFinder

Parameters:

addrs - Addresses discovery SPI binds to.

Throws:

GridSpiException - In case of error.

isShared

public boolean isShared()

Checks whether IP finder is shared or not.

If it is shared then only coordinator can unregister addresses.

All nodes should register their address themselves, as early as possible on node start.

Specified by:

isShared in interface GridTcpDiscoveryIpFinder

Returns:

true if IP finder is shared.

setShared

@GridSpiConfiguration(optional=true)
public void setShared(boolean shared)

Sets shared flag. If true then it is expected that IP addresses registered with IP finder will be seen by IP finders on all other nodes.

Parameters:

shared - true if this IP finder is shared.

toString

public String toString()

Overrides:

toString in class Object

close

public void close()

Closes this IP finder and releases any system resources associated with it.

Specified by:

close in interface GridTcpDiscoveryIpFinder

spiContext

protected GridSpiContext spiContext()

Returns:

SPI context.
