Method Detail- 
onSpiContextInitializedpublic void onSpiContextInitialized(IgniteSpiContext spiCtx) throws IgniteSpiException Callback invoked when SPI context is initialized afterTcpDiscoverySpi.spiStart(String)method is completed, SPI context can be stored for future access.- Specified by:
- onSpiContextInitializedin interface- TcpDiscoveryIpFinder
- Parameters:
- spiCtx- Spi context.
- Throws:
- IgniteSpiException- In case of error.
 
 - 
onSpiContextDestroyedpublic 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:
- onSpiContextDestroyedin interface- TcpDiscoveryIpFinder
 
 - 
initializeLocalAddressespublic void initializeLocalAddresses(Collection<InetSocketAddress> addrs) throws IgniteSpiException Initializes addresses discovery SPI binds to.- Specified by:
- initializeLocalAddressesin interface- TcpDiscoveryIpFinder
- Parameters:
- addrs- Addresses discovery SPI binds to.
- Throws:
- IgniteSpiException- In case of error.

isSharedpublic boolean isShared() Checks whether IP finder is shared or not.If this property is set to truethen IP finder allows to add and remove addresses in runtime and this is how, for example, IP finder should work in Amazon EC2 environment or any other environment where IPs may not be known beforehand.If this property is set to falsethen IP finder is immutable and all the addresses should be listed in configuration before Ignite start. This is the most use case for IP finders local to current VM. Since, usually such IP finders are created per each Ignite instance and all the known IPs are listed right away, but there is also an option to make such IP finders shared by setting this property totrueand literally share it between local VM Ignite instances. This way user does not have to list any IPs before start, instead all starting nodes add their addresses to the finder, then get the registered addresses and continue with discovery procedure.- Specified by:
- isSharedin interface- TcpDiscoveryIpFinder
- Returns:
- trueif IP finder is shared.
 
 - 
setShared@IgniteSpiConfiguration(optional=true) public TcpDiscoveryIpFinderAdapter setShared(boolean shared) Sets shared flag. Iftruethen it is expected that IP addresses registered with IP finder will be seen by IP finders on all other nodes.- Parameters:
- shared-- trueif this IP finder is shared.
- Returns:
- thisfor chaining.
 
 - 
closepublic void close() Closes this IP finder and releases any system resources associated with it.- Specified by:
- closein interface- TcpDiscoveryIpFinder
 
 - 
discoveryClientMode@Deprecated protected boolean discoveryClientMode() Deprecated.Since 2.8. May return incorrect value if client and server nodes shares sameTcpDiscoveryIpFinderinstance.- Returns:
- Trueif TCP discovery works in client mode.
 
 - 
spiContextprotected IgniteSpiContext spiContext() - Returns:
- SPI context.
