All Implemented Interfaces:

JsonFormatVisitable, SchemaAware, ContextualSerializer, Serializable

Enclosing class:

NumberSerializers

public static final class NumberSerializers.IntegerSerializer
extends NumberSerializers.Base<Object>

This is the special serializer for regular Integers (and primitive ints)

Since this is one of "native" types, no type information is ever included on serialization (unlike for most scalar types)

NOTE: as of 2.6, generic signature changed to Object, to avoid generation of bridge methods.

Method Summary

Modifier and Type	Method and Description
boolean	isEmpty(SerializerProvider prov, Object value) Method called to check whether given serializable value is considered "empty" value (for purposes of suppressing serialization of empty values).
void	serialize(Object value, com.fasterxml.jackson.core.JsonGenerator gen, SerializerProvider provider) Method that can be called to ask implementation to serialize values of type this serializer handles.
void	serializeWithType(Object value, com.fasterxml.jackson.core.JsonGenerator gen, SerializerProvider provider, TypeSerializer typeSer) Default implementation will write type prefix, call regular serialization method (since assumption is that value itself does not need JSON Array or Object start/end markers), and then write type suffix.

Method Detail

serialize

public void serialize(Object value,
                      com.fasterxml.jackson.core.JsonGenerator gen,
                      SerializerProvider provider)
               throws IOException

Description copied from class: JsonSerializer

Method that can be called to ask implementation to serialize values of type this serializer handles.

Specified by:

serialize in class StdSerializer<Object>

Parameters:

value - Value to serialize; can not be null.

gen - Generator used to output resulting Json content

provider - Provider that can be used to get serializers for serializing Objects value contains, if any.

Throws:

IOException

serializeWithType

public void serializeWithType(Object value,
                              com.fasterxml.jackson.core.JsonGenerator gen,
                              SerializerProvider provider,
                              TypeSerializer typeSer)
                       throws IOException

Description copied from class: StdScalarSerializer

Default implementation will write type prefix, call regular serialization method (since assumption is that value itself does not need JSON Array or Object start/end markers), and then write type suffix. This should work for most cases; some sub-classes may want to change this behavior.

Overrides:

serializeWithType in class StdScalarSerializer<Object>

Parameters:

value - Value to serialize; can not be null.

gen - Generator used to output resulting Json content

provider - Provider that can be used to get serializers for serializing Objects value contains, if any.

typeSer - Type serializer to use for including type information

Throws:

IOException

isEmpty

public boolean isEmpty(SerializerProvider prov,
                       Object value)

Description copied from class: JsonSerializer

Method called to check whether given serializable value is considered "empty" value (for purposes of suppressing serialization of empty values).

Default implementation will consider only null values to be empty.

NOTE: replaces JsonSerializer.isEmpty(Object), deprecated in 2.5

Overrides:

isEmpty in class JsonSerializer<Object>
