Class SimpleEntryFactory

java.lang.Object

com.cedarsoftware.io.factory.SimpleEntryFactory

All Implemented Interfaces:

ClassFactory

public class SimpleEntryFactory
extends Object
implements ClassFactory

Factory class to create AbstractMap.SimpleEntry and AbstractMap.SimpleImmutableEntry instances.

These classes have final fields that cannot be set via reflection on Java 9+, so we must use the constructor to create properly initialized instances.

Handles both:

• AbstractMap.SimpleEntry - mutable entry (value can be changed)
• AbstractMap.SimpleImmutableEntry - immutable entry

Method Details

newInstance

public Object newInstance(Class<?> c,
 JsonObject jObj,
 Resolver resolver)

Creates a new SimpleEntry or SimpleImmutableEntry instance using values from the JsonObject.

Specified by:

newInstance in interface ClassFactory

Parameters:

c - The class to instantiate (SimpleEntry or SimpleImmutableEntry)

jObj - The JsonObject containing "key" and "value" fields

resolver - The resolver for converting nested objects

Returns:

A new entry instance with the key and value set

isObjectFinal

public boolean isObjectFinal()

Returns true because the entry is fully constructed by this factory. No further field processing is needed.

Specified by:

isObjectFinal in interface ClassFactory

Returns:

true if this object is instantiated and completely filled using the contents from the JsonObject. In this case, no further processing will be performed on the instance. If the object has sub-objects (complex fields), then return false so that json-io will continue filling out the remaining portion of the object.
