Class FailingSerializer

java.lang.Object

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

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

com.fasterxml.jackson.databind.ser.impl.FailingSerializer

All Implemented Interfaces:

JsonFormatVisitable, SchemaAware, Serializable

public class FailingSerializer
extends StdSerializer<Object>

Special bogus "serializer" that will throw JsonMappingException if its serialize(java.lang.Object, com.fasterxml.jackson.core.JsonGenerator, com.fasterxml.jackson.databind.SerializerProvider) gets invoked. Most commonly registered as handler for unknown types, as well as for catching unintended usage (like trying to use null as Map/Object key).

Method Detail

serialize

public void serialize(Object 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<Object>

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

public JsonNode getSchema(SerializerProvider provider,
                          Type typeHint)
                   throws JsonMappingException

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 StdSerializer<Object>

Parameters:

provider - The serializer provider.

typeHint - A hint about the type.

Returns:

Json-schema for this serializer.

Throws:

JsonMappingException

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 StdSerializer<Object>

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