prefix

public static final java.lang.String prefix

All keys are prefixed with this string

Constant Field Values

KRYO_CLASS

public static final java.lang.String KRYO_CLASS

Name of the subclass of kryo to instantiate to start with. If this is empty, we use Kryo.class

See Also:

Constant Field Values

KRYO_CLASS_DEFAULT

public static final java.lang.String KRYO_CLASS_DEFAULT

INSTANTIATOR_STRATEGY_CLASS

public static final java.lang.String INSTANTIATOR_STRATEGY_CLASS

Name of the InstatiatorStrategy to use. If this is empty, we use org.objenesis.strategy.StdInstantiatorStrategy

See Also:

Constant Field Values

INSTANTIATOR_STRATEGY_CLASS_DEFAULT

public static final java.lang.String INSTANTIATOR_STRATEGY_CLASS_DEFAULT

REGISTRATIONS

public static final java.lang.String REGISTRATIONS

KRYO_REGISTRATIONS holds a colon-separated list of classes to register with Kryo. For example, the following value: "someClass,someSerializer:otherClass:thirdClass,thirdSerializer" will direct KryoFactory to register someClass and thirdClass with custom serializers and otherClass with Kryo's FieldsSerializer.

Constant Field Values

DEFAULT_REGISTRATIONS

public static final java.lang.String DEFAULT_REGISTRATIONS

DEFAULT_REGISTRATIONS holds a colon-separated list of classes or interfaces to register with Kryo. Default Registrations are searched after basic registrations, and have the ability to capture objects that are assignable from the hierarchy's superclass. For example, the following value: "someClass,someSerializer:someInterface,otherSerializer" will configure to serializeobjects that extend from someClass with someSerializer, and objects that extend someInterface with otherSerializer.

Constant Field Values

SKIP_MISSING

public static final java.lang.String SKIP_MISSING

If SKIP_MISSING is set to false, Kryo will throw an error when Cascading tries to register a class or serialization that doesn't exist.

See Also:

Constant Field Values

SKIP_MISSING_DEFAULT

public static final boolean SKIP_MISSING_DEFAULT

See Also:

Constant Field Values

REGISTRATION_REQUIRED

public static final java.lang.String REGISTRATION_REQUIRED

If REGISTRATION_REQUIRED is set to false, Kryo will try to serialize all java objects, not just those with custom serializations registered.
