Method Detail- 
onSpiContextInitializedvoid 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.- Parameters:
- spiCtx- Spi context.
- Throws:
- IgniteSpiException- In case of error.
 
 - 
onSpiContextDestroyedvoid 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.
 - 
initializeLocalAddressesvoid initializeLocalAddresses(Collection<InetSocketAddress> addrs) throws IgniteSpiException Initializes addresses discovery SPI binds to.- Parameters:
- addrs- Addresses discovery SPI binds to.
- Throws:
- IgniteSpiException- In case of error.
 
 - 
getRegisteredAddressesCollection<InetSocketAddress> getRegisteredAddresses() throws IgniteSpiException Gets all addresses registered in this finder.- Returns:
- All known addresses, potentially empty, but never null.
- Throws:
- IgniteSpiException- In case of error.
 
 - 
isSharedboolean 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.- Returns:
- trueif IP finder is shared.
 
 - 
registerAddressesvoid registerAddresses(Collection<InetSocketAddress> addrs) throws IgniteSpiException Registers new addresses.Implementation should accept duplicates quietly, but should not register address if it is already registered. - Parameters:
- addrs- Addresses to register. Not- nulland not empty.
- Throws:
- IgniteSpiException- In case of error.
 
 - 
unregisterAddressesvoid unregisterAddresses(Collection<InetSocketAddress> addrs) throws IgniteSpiException Unregisters provided addresses.Implementation should accept addresses that are currently not registered quietly (just no-op). - Parameters:
- addrs- Addresses to unregister. Not- nulland not empty.
- Throws:
- IgniteSpiException- In case of error.
 
 - 
closevoid close() Closes this IP finder and releases any system resources associated with it.
