2.16.1-beta10

Enhancements

Some minor refactoring

#206 #211

Breaking changes

The ValueClassDeserializer has been renamed to WrapsNullableValueClassDeserializer

Despite its name, there was no need to use this class other than as a value class to wrap nullables.
Therefore, it has been modified to use a special name.

#211

2.16.0-beta9

Enhancements

Enhanced deserialization support for value class wrapping nullable

If the argument is a value class and non-null that wraps nullable and the input is explicit null, deserialization would previously have failed.
On the other hand, from now on the wrapped null will be used.

It is also now possible for users to customize this behavior by implementing a ValueClassDeserializer.
#196

Breaking changes

The exception thrown by the KotlinValueInstantiator is now InvalidNullException

And the attached message has been changed to default to InvalidNullException.
#195

Bigfixes

Fix handling of vararg deserialization

When vararg arguments were used during deserialization, there was a problem with them being treated like non-null arrays.
Now it is handled as follows.

• Marked as not isRequired.
• If the input is undefined, an empty array is used by default
  #197

Fixed a problem where the Nulls setting was ignored if the input was undefined

Previously, in Kogera, if the input was undefined and no default argument was set, the nullValueProvider was not called and the value of JsonSetter(nulls = ) was ignored.
This behavior differed from that of kotlin-module in that it did not generate the error expected for primitive types.

Therefore, a change has been made to always call nullValueProvider if the input is undefined.

Note that this change changes the behavior when undefined input is received if you are using a JsonDeserializer that implements absentValue to return a non-null value.

2.16.0-beta8

Enhancements

Fix deserialization method of value class

Internal implementation changes have been made regarding deserialization of value class.
This allows the following functionality to be used

• Deserializer specification by JsonDeserialize annotation
• Allow absentValue set to deserializer to return value class
• Injection of value class by JacksonInject

#183

Note that an error will now occur if you have set an absentValue or other value class that is unboxed.

Access checks to ValueCreator are now performed earlier

#182

Remove unnecessary judgment when a value is missing during deserialization.

This is expected to improve deserialization performance, albeit slightly.
#186

Bigfixes

Implement readResolve for serializable objects

#182

Fixed a problem where some KDoc links were broken

#182

2.16.0-beta7

Enhancements

Update library versions

First, the version of Jackson is now 2.16.0.

Also, kotlinx-metadata-jvm has been updated to 0.7.0, and along with it, the version of Kotlin is now 1.8.22.
The minimum Kotlin version for this project is the lowest Kotlin version required by kotlinx-metadata-jvm.
#175

Reduced resource usage when registering the same KotlinModule instance to multiple mappers

Only one instance of the internal support classes are now created for each instance of KotlinModule.
This improves resource efficiency and initialization performance when registering KotlinModule to multiple Mappers.
See #173 for details.

Cache sizes may need to be reviewed for hard use cases, as internal processing caches will also be shared.
Also note that calling the set method on a KotlinModule can destroy the functionality of the KotlinModule.

Updating kotlinter.

To update kotlinter, some changes have been made to internal package names, etc.
This change does not affect the published API.
#170
#171
#172

Breaking changes

Consolidate cache size to one property.

The initialCacheSize/maxCacheSize properties have been removed and merged into cacheSize: KotlinModule.CacheSize.
#176

Bigfixes

Implement readResolve for object which implements Serializable.

The problem of multiple instances of object being created during the JDK deserialization process has been fixed.
#174

2.15.3-beta6

Enhancements

Improve efficiency of reflection cache

The problem of infrequently used caches being retained has been eliminated, and the maximum number of records to be retained as a cache has been reduced.
See #164 for details.

Please note that the reflectionCacheSize property has been removed and split into initialCacheSize and maxCacheSize.

Improved efficiency of strictNullCheck

Previously strictNullCheck was done by Kogeras own Converter, but now JsonSetter(contentNulls = FAIL) is used.
This makes null checking more efficient and error messages clearer (from now on InvalidNullException will be thrown).

If you have implemented findSetterInfo by your own AnnotationIntrospector, or if your JsonSetter annotation has a non-DEFAULT value for contentNulls, the strictNullCheck may not work as intended.
Also, although unconfirmed, there is a possibility that the behavior may change when the Converter (Deserializer) is no longer used.
