Class ConfigCheck

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)

getFactoryId

public int getFactoryId()

Description copied from interface: IdentifiedDataSerializable

Returns DataSerializableFactory factory ID for this class.

Specified by:

getFactoryId in interface IdentifiedDataSerializable

Returns:

factory ID

getId

public int getId()

Description copied from interface: IdentifiedDataSerializable

Returns type identifier for this class. It should be unique per DataSerializableFactory.

Specified by:

getId in interface IdentifiedDataSerializable

Returns:

type ID

writeData

public void writeData(ObjectDataOutput out)
               throws IOException

Description copied from interface: DataSerializable

Writes object fields to output stream

Specified by:

writeData in interface DataSerializable

Parameters:

out - output

Throws:

IOException - if an I/O error occurs. In particular, an IOException may be thrown if the output stream has been closed.

readData

public void readData(ObjectDataInput in)
              throws IOException

Description copied from interface: DataSerializable

Reads fields from the input stream

Specified by:

readData in interface DataSerializable

Parameters:

in - input

Throws:

IOException - if an I/O error occurs. In particular, an IOException may be thrown if the input stream has been closed.
