java.lang.Object

com.hazelcast.internal.cluster.impl.ConfigCheck

All Implemented Interfaces:

DataSerializable, IdentifiedDataSerializable

public final class ConfigCheck
extends Object
implements IdentifiedDataSerializable

Contains enough information about Hazelcast Config, to do a validation check so that clusters with different configurations don't join.

Method Detail

isCompatible

public boolean isCompatible(ConfigCheck found)

Checks if two Hazelcast configurations are compatible.

Parameters:

found - the ConfigCheck to compare this to

Returns:

true if compatible. False if part of another group.

Throws:

ConfigMismatchException - if the configuration is not compatible. An exception is thrown so we can pass a nice message.

isSameGroup

public boolean isSameGroup(ConfigCheck found)
