craterdog.smart

Class SmartObject<S extends SmartObject<S>>

java.lang.Object

craterdog.smart.SmartObject<S>

Type Parameters:

S - The concrete type of the smart object.

All Implemented Interfaces:

craterdog.core.Composite, Comparable<S>

public abstract class SmartObject<S extends SmartObject<S>>
extends Object
implements Comparable<S>, craterdog.core.Composite

This abstract class provides implementations for the standard methods defined in the Object class. It also adds a generics based copy() method that is superior to the clone() method in many ways.

SmartObject

public SmartObject()

Method Detail

toString

public String toString()

This method returns a string containing a structured, human readable version of the object. The string is formatted in Javascript Object Notation (JSON).

Specified by:

toString in interface craterdog.core.Composite

Overrides:

toString in class Object

Returns:

The formatted JSON string.

toString

public String toString(String indentation)

Specified by:

toString in interface craterdog.core.Composite

toExposedString

protected String toExposedString()

This method behaves similarly to the toString() method except that it does not perform any censorship of sensitive attributes. It should only be used when the resulting output will not be stored or seen by anyone.

Returns:

The formatted JSON string.

equals

public boolean equals(Object object)

This method determines whether or not two objects are equal. Two objects are equal if they have the same class type and all their attributes and sub-components are equal.

Overrides:

equals in class Object

Parameters:

object - The object to be compared with this object.

Returns:

Whether or not the two objects are equal.

compareTo

public int compareTo(S object)

Specified by:

compareTo in interface Comparable<S extends SmartObject<S>>

copy

public <T extends S> T copy()

This method should work for all objects. However, it is very inefficient and should only be used sparingly and for unit testing.

Type Parameters:

T - The concrete type of the smart object.

Returns:

An exact copy of the smart object.

hashCode

public int hashCode()

This method returns a hash code for the object based on its string form. This is not a very efficient method.

Overrides:

hashCode in class Object

Returns:

A hash code for the object.

addSerializableClass

protected void addSerializableClass(Class<?> serializable)

This protected method allows a subclass to add a class type that can be serialized using its toString() method to the mappers.

Parameters:

serializable - The type of class that can be serialized using its toString() method.

addSerializableClass

protected void addSerializableClass(com.fasterxml.jackson.databind.Module module)

This protected method allows a subclass to add a Jackson module to the set of modules used by the mappers.

Parameters:

module - The type of class that can be serialized using its toString() method.
