Examples of com.fasterxml.jackson.databind.JsonSerializer

com.fasterxml.jackson.databind.JsonSerializer
Abstract class that defines API used by {@link ObjectMapper} (andother chained {@link JsonSerializer}s too) to serialize Objects of arbitrary types into JSON, using provided {@link JsonGenerator}.
NOTE: it is recommended that custom serializers extend {@link com.fasterxml.jackson.databind.ser.std.StdSerializer} insteadof this class, since it will implement many of optional methods of this class.
If serializer is an aggregate one -- meaning it delegates handling of some of its contents by using other serializer(s) -- it typically also needs to implement {@link com.fasterxml.jackson.databind.ser.ResolvableSerializer}, which can locate secondary serializers needed. This is important to allow dynamic overrides of serializers; separate call interface is needed to separate resolution of secondary serializers (which may have cyclic link back to serializer itself, directly or indirectly).
In addition, to support per-property annotations (to configure aspects of serialization on per-property basis), serializers may want to implement {@link com.fasterxml.jackson.databind.ser.ContextualSerializer}, which allows specialization of serializers: call to {@link com.fasterxml.jackson.databind.ser.ContextualSerializer#createContextual}is passed information on property, and can create a newly configured serializer for handling that particular property.
If both {@link com.fasterxml.jackson.databind.ser.ResolvableSerializer} and{@link com.fasterxml.jackson.databind.ser.ContextualSerializer}are implemented, resolution of serializers occurs before contextualization.
