All Implemented Interfaces:

JsonFormatVisitable

public final class BooleanSerializer
extends StdScalarSerializer<Object>

Serializer used for primitive boolean, as well as java.util.Boolean wrapper type.

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

Method Summary

Modifier and Type	Method	Description
void	acceptJsonFormatVisitor(JsonFormatVisitorWrapper visitor, JavaType typeHint)	Default implementation specifies no format.
ValueSerializer<?>	createContextual(SerializationContext serializers, BeanProperty property)	Method called to see if a different (or differently configured) serializer is needed to serialize values of specified property (or, for root values, in which case `null` is passed).
void	serialize(Object value, JsonGenerator g, SerializationContext provider)	Method that can be called to ask implementation to serialize values of type this serializer handles.
final void	serializeWithType(Object value, JsonGenerator g, SerializationContext 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 Details

createContextual

public ValueSerializer<?> createContextual(SerializationContext serializers,
 BeanProperty property)

Description copied from class: ValueSerializer

Method called to see if a different (or differently configured) serializer is needed to serialize values of specified property (or, for root values, in which case `null` is passed). Note that instance that this method is called on is typically shared one and as a result method should NOT modify this instance but rather construct and return a new instance. This instance should only be returned as-is, in case it is already suitable for use.

Note that method is only called once per POJO property, and for the first usage as root value serializer; it is not called for every serialization, as doing that would have significant performance impact; most serializers cache contextual instances for future use.

Overrides:

createContextual in class ValueSerializer<Object>

Parameters:

serializers - Context to use for accessing config, other serializers

property - Property (defined by one or more accessors - field or method - used for accessing logical property value) for which serializer is used to be used; or, `null` for root value (or in cases where caller does not have this information, which is handled as root value case).

Returns:

Serializer to use for serializing values of specified property; may be this instance or a new instance.

serialize

public void serialize(Object value,
 JsonGenerator g,
 SerializationContext provider)
               throws JacksonException

Description copied from class: ValueSerializer

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.

g - Generator used to output resulting Json content

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

Throws:

JacksonException

serializeWithType

public final void serializeWithType(Object value,
 JsonGenerator g,
 SerializationContext provider,
 TypeSerializer typeSer)
                             throws JacksonException

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.

g - Generator used to output resulting Json content

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

typeSer - Type serializer to use for including type information

Throws:

JacksonException

acceptJsonFormatVisitor

public void acceptJsonFormatVisitor(JsonFormatVisitorWrapper visitor,
 JavaType typeHint)

Description copied from class: StdSerializer

Default implementation specifies no format. This behavior is usually overriden by custom serializers.

Specified by:

acceptJsonFormatVisitor in interface JsonFormatVisitable

Overrides:

acceptJsonFormatVisitor in class StdScalarSerializer<Object>

typeHint - Type of element (entity like property) being visited
