Class BaseValueObject

java.lang.Object

org.seedstack.business.domain.BaseValueObject

All Implemented Interfaces:

Serializable, DomainObject, ValueObject, Producible

Direct Known Subclasses:

DomainEvent

public abstract class BaseValueObject
extends Object
implements ValueObject, Serializable

This class is the inheritance base for ValueObject implementations. It offers specific equals() and hashCode() methods which are computed by reflection on all non-transient field values. If performance is critical, consider overriding those methods with optimized versions. Be sure to respect the equality semantics for value objects when doing so.

public BaseValueObject()

Method Detail

hashCode

public int hashCode()

Computes the hash code by reflection on all non-transient fields. This method can is quite costly and may be overridden by an optimized version if performance is critical. Be sure to respect the equality semantics for value objects when doing so.

Specified by:

hashCode in interface ValueObject

Overrides:

hashCode in class Object

Returns:

Hash code built from all non-transient fields.

equals

public boolean equals(Object other)

Computes the equality by reflection on all non-transient fields. This method can is quite costly and may be overridden by an optimized version if performance is critical. Be sure to respect the equality semantics for value objects when doing so.

Specified by:

equals in interface ValueObject

Overrides:

equals in class Object

Parameters:

other - other object

Returns:

true if the other object is a ValueObject and has the same value as this value object, false otherwise.

toString

public String toString()

Specified by:

toString in interface ValueObject

Overrides:

toString in class Object
