tools.jackson.databind.ser.jdk.NumberSerializer

All Implemented Interfaces:

JsonFormatVisitable

public class NumberSerializer
extends StdScalarSerializer<Number>

As a fallback, we may need to use this serializer for other types of Numbers: both custom types and "big" numbers like BigInteger and BigDecimal.

Method Details

createContextual

public ValueSerializer<?> createContextual(SerializationContext prov,
 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<Number>

Parameters:

prov - 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(Number 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<Number>

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

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<Number>

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

bigDecimalAsStringSerializer

public static ValueSerializer<?> bigDecimalAsStringSerializer()

Since:
