Method Detail

addDefaultKryoSerializer

public <T extends com.esotericsoftware.kryo.Serializer<?> & Serializable> void addDefaultKryoSerializer(Class<?> type,
                                                                                                        T serializer)

Adds a new Kryo default serializer to the Runtime.

Note that the serializer instance must be serializable (as defined by java.io.Serializable), because it may be distributed to the worker nodes by java serialization.

Specified by:

addDefaultKryoSerializer in interface SerializerConfig

Parameters:

type - The class of the types serialized with the given serializer.

serializer - The serializer to use.

addDefaultKryoSerializer

public void addDefaultKryoSerializer(Class<?> type,
                                     Class<? extends com.esotericsoftware.kryo.Serializer<?>> serializerClass)

Adds a new Kryo default serializer to the Runtime.

Specified by:

addDefaultKryoSerializer in interface SerializerConfig

Parameters:

type - The class of the types serialized with the given serializer.

serializerClass - The class of the serializer to use.

registerTypeWithKryoSerializer

public <T extends com.esotericsoftware.kryo.Serializer<?> & Serializable> void registerTypeWithKryoSerializer(Class<?> type,
                                                                                                              T serializer)

Registers the given type with a Kryo Serializer.

Note that the serializer instance must be serializable (as defined by java.io.Serializable), because it may be distributed to the worker nodes by java serialization.

Specified by:

registerTypeWithKryoSerializer in interface SerializerConfig

Parameters:

type - The class of the types serialized with the given serializer.

serializer - The serializer to use.

registerTypeWithKryoSerializer

public void registerTypeWithKryoSerializer(Class<?> type,
                                           Class<? extends com.esotericsoftware.kryo.Serializer> serializerClass)

Registers the given Serializer via its class as a serializer for the given type at the KryoSerializer.

Specified by:

registerTypeWithKryoSerializer in interface SerializerConfig

Parameters:

type - The class of the types serialized with the given serializer.

serializerClass - The class of the serializer to use.

registerPojoType

public void registerPojoType(Class<?> type)

Registers the given type with the serialization stack. If the type is eventually serialized as a POJO, then the type is registered with the POJO serializer. If the type ends up being serialized with Kryo, then it will be registered at Kryo to make sure that only tags are written.

Specified by:

registerPojoType in interface SerializerConfig

Parameters:

type - The class of the type to register.

registerKryoType

public void registerKryoType(Class<?> type)

Registers the given type with the serialization stack. If the type is eventually serialized as a POJO, then the type is registered with the POJO serializer. If the type ends up being serialized with Kryo, then it will be registered at Kryo to make sure that only tags are written.

Specified by:

registerKryoType in interface SerializerConfig

Parameters:

type - The class of the type to register.

public boolean isForceKryoEnabled()

Returns whether Kryo is the serializer for POJOs.

Specified by:

isForceKryoEnabled in interface SerializerConfig

setForceKryo

public void setForceKryo(boolean forceKryo)
