Class NumberSerializer

java.lang.Object

com.fasterxml.jackson.databind.JsonSerializer<Number>

com.fasterxml.jackson.databind.ser.std.StdSerializer<Number>

com.fasterxml.jackson.databind.ser.std.StdScalarSerializer<Number>

com.fasterxml.jackson.databind.ser.std.NumberSerializer

All Implemented Interfaces:

JsonFormatVisitable, SchemaAware, ContextualSerializer, Serializable

public class NumberSerializer
extends StdScalarSerializer<Number>
implements ContextualSerializer

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 JsonSerializer<?> createContextual(SerializerProvider prov,
 BeanProperty property)
                                   throws JsonMappingException

Description copied from interface: ContextualSerializer

Method called to see if a different (or differently configured) serializer is needed to serialize values of specified property. 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.

Specified by:

createContextual in interface ContextualSerializer

Parameters:

prov - Serializer provider to use for accessing config, other serializers

property - Method or field that represents the property (and is used to access value to serialize). Should be available; but there may be cases where caller cannot provide it and null is passed instead (in which case impls usually pass 'this' serializer as is)

Returns:

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

Throws:

JsonMappingException

serialize

public void serialize(Number value,
 JsonGenerator g,
 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<Number>

Parameters:

value - Value to serialize; can not be null.

g - 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

getSchema

@Deprecated
public JsonNode getSchema(SerializerProvider provider,
 Type typeHint)

Deprecated.

Since 2.15

Description copied from class: StdSerializer

Default implementation simply claims type is "string"; usually overriden by custom serializers.

Specified by:

getSchema in interface SchemaAware

Overrides:

getSchema in class StdScalarSerializer<Number>

Parameters:

provider - The serializer provider.

typeHint - A hint about the type.

Returns:

Json-schema for this serializer.

acceptJsonFormatVisitor

public void acceptJsonFormatVisitor(JsonFormatVisitorWrapper visitor,
 JavaType typeHint)
                             throws JsonMappingException

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>

Parameters:

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

Throws:

JsonMappingException

bigDecimalAsStringSerializer

public static JsonSerializer<?> bigDecimalAsStringSerializer()

Since:

2.10
