BeanSerializerFactory
public abstract class BasicSerializerFactory extends SerializerFactory implements java.io.Serializable
Factory class that can provide serializers for standard JDK classes, as well as custom classes that extend standard classes or implement one of "well-known" interfaces (such asCollection
).Since all the serializers are eagerly instantiated, and there is no additional introspection or customizability of these types, this factory is essentially stateless.

_concrete
protected static final java.util.HashMap<java.lang.String,JsonSerializer<?>> _concrete
Since these are all JDK classes, we shouldn't have to worry about ClassLoader used to load them. Rather, we can just use the class name, and keep things simple and efficient.

Method Detail
-
getFactoryConfig
public SerializerFactoryConfig getFactoryConfig()
Method for getting currentSerializerFactoryConfig
.Note that since instances are immutable, you can NOT change settings by accessing an instance and calling methods: this will simply create new instance of config object.
-
withConfig
public abstract SerializerFactory withConfig(SerializerFactoryConfig config)
Method used for creating a new instance of this factory, but with different configuration. Reason for specifying factory method (instead of plain constructor) is to allow proper sub-classing of factories.Note that custom sub-classes generally must override implementation of this method, as it usually requires instantiating a new instance of factory type.

BeanSerializerFactory
for more details.
