SimpleSerializers (jackson-databind 2.12.5)

java.lang.Object
- com.fasterxml.jackson.databind.ser.Serializers.Base
- - com.fasterxml.jackson.databind.module.SimpleSerializers

All Implemented Interfaces:

Serializers, Serializable
```
public class SimpleSerializers
extends Serializers.Base
implements Serializable
```
Simple implementation Serializers which allows registration of serializers based on raw (type erased class). It can work well for basic bean and scalar type serializers, but is not a good fit for handling generic types (like Maps and Collections).
Type registrations are assumed to be general; meaning that registration of serializer for a super type will also be used for handling subtypes, unless an exact match is found first. As an example, handler for CharSequence would also be used serializing StringBuilder instances, unless a direct mapping was found.

Method for adding given serializer for type that JsonSerializer.handledType() specifies (which MUST return a non-null class; and can NOT be Object, as a sanity check). For serializers that do not declare handled type, use the variant that takes two arguments.

Description copied from interface: Serializers

Method called by serialization framework first time a serializer is needed for specified type, which is not of a container or reference type (for which other methods are called).

Specified by:

findSerializer in interface Serializers

Overrides:

findSerializer in class Serializers.Base

Parameters:

config - Serialization configuration in use

type - Fully resolved type of instances to serialize

beanDesc - Additional information about type

Returns:

Configured serializer to use for the type; or null if implementation does not recognize or support type
