Class LazyDeserializingObject<T>

java.lang.Object

org.axonframework.serialization.LazyDeserializingObject<T>

Type Parameters:

T - The type of object contained in the serialized object

public class LazyDeserializingObject<T>
extends Object

Represents a serialized object that can be deserializedObjects upon request. Typically used as a wrapper class for keeping a SerializedObject and its Serializer together.

2.0

Constructor Detail

LazyDeserializingObject

public LazyDeserializingObject(T deserializedObject)

Creates an instance with the given deserializedObject object instance. Using this constructor will ensure that no deserializing is required when invoking the getType() or getObject() methods.

Parameters:

deserializedObject - The deserialized object to return on getObject()

LazyDeserializingObject

public LazyDeserializingObject(SerializedObject<?> serializedObject,
                               Serializer serializer)

Creates an instance which will deserialize given serializedObject upon request. Use this constructor if the serializedObject is already available and does not need to undergo a process of e.g. upcasting.

Parameters:

serializedObject - The serialized payload of the message

serializer - The serializer to deserialize the payload data with

Throws:

UnknownSerializedTypeException - if the type of the serialized object cannot be resolved to a class

LazyDeserializingObject

public LazyDeserializingObject(Supplier<SerializedObject<?>> serializedObjectSupplier,
                               SerializedType serializedType,
                               Serializer serializer)

Creates an instance which will get the supplied SerializedObject and deserialize it upon request. Use this constructor if getting the SerializedObject is an 'expensive operation', e.g. if the SerializedObject still needs to be upcasted.

Parameters:

serializedObjectSupplier - The supplier of the serialized object

serializedType - The type of the serialized object

serializer - The serializer to deserialize the payload data with

Throws:

UnknownSerializedTypeException - if the type of the serialized object cannot be resolved to a class

Method Detail

getType

public Class<T> getType()

Returns the class of the serialized object.

Returns:

the class of the serialized object

getObject

public T getObject()

De-serializes the object and returns the result.

Returns:

the deserialized object

isDeserialized

public boolean isDeserialized()

Indicates whether this object has already been deserialized. When this method returns true, the getObject() method is able to return a value without invoking the serializer.

Returns:

whether the contained object has been deserialized already.

getSerializer

public Serializer getSerializer()

Returns the serializer to deserialize this object

Returns:

the serializer to deserialize this object

getSerializedObject

public SerializedObject<?> getSerializedObject()

Returns the serialized object to deserialize upon request

Returns:

the serialized object to deserialize upon request
