ObjectArraySerializer

public ObjectArraySerializer(JavaType elemType,
                     boolean staticTyping,
                     TypeSerializer vts,
                     JsonSerializer<Object> elementSerializer)

                     TypeSerializer vts,
                     JsonSerializer<?> elementSerializer)

Method Detail

_withValueTypeSerializer

public ContainerSerializer<?> _withValueTypeSerializer(TypeSerializer vts)

Description copied from class: ContainerSerializer

Method that needs to be implemented to allow construction of a new serializer object with given TypeSerializer, used when addition type information is to be embedded.

Specified by:

_withValueTypeSerializer in class ContainerSerializer<Object[]>

withResolved

public ObjectArraySerializer withResolved(BeanProperty prop,
                                 TypeSerializer vts,
                                 JsonSerializer<?> ser)

createContextual

public JsonSerializer<?> createContextual(SerializerProvider provider,
                                 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:

provider - 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 can not 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

getContentType

public JavaType getContentType()

Description copied from class: ContainerSerializer

Accessor for finding declared (static) element type for type this serializer is used for.

Specified by:

getContentType in class ContainerSerializer<Object[]>

getContentSerializer

public JsonSerializer<?> getContentSerializer()

Description copied from class: ContainerSerializer

Accessor for serializer used for serializing contents (List and array elements, Map values etc) of the container for which this serializer is used, if it is known statically. Note that for dynamic types this may return null; if so, caller has to instead use ContainerSerializer.getContentType() and SerializerProvider.findValueSerializer(java.lang.Class<?>, com.fasterxml.jackson.databind.BeanProperty).

Specified by:

getContentSerializer in class ContainerSerializer<Object[]>

isEmpty

public boolean isEmpty(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.

Specified by:

isEmpty in class ContainerSerializer<Object[]>

hasSingleElement

public boolean hasSingleElement(Object[] value)

Description copied from class: ContainerSerializer

Method called to determine if the given value (of type handled by this serializer) contains exactly one element.

Note: although it might seem sensible to instead define something like "getElementCount()" method, this would not work well for containers that do not keep track of size (like linked lists may not).

Specified by:

hasSingleElement in class ContainerSerializer<Object[]>

serializeContents

public void serializeContents(Object[] value,
                     com.fasterxml.jackson.core.JsonGenerator jgen,
                     SerializerProvider provider)
                       throws IOException,
                              com.fasterxml.jackson.core.JsonGenerationException

Specified by:

serializeContents in class ArraySerializerBase<Object[]>

Throws:

IOException

com.fasterxml.jackson.core.JsonGenerationException

serializeContentsUsing

public void serializeContentsUsing(Object[] value,
                          com.fasterxml.jackson.core.JsonGenerator jgen,
                          SerializerProvider provider,
                          JsonSerializer<Object> ser)
                            throws IOException,
                                   com.fasterxml.jackson.core.JsonGenerationException

Throws:

IOException

com.fasterxml.jackson.core.JsonGenerationException

serializeTypedContents

public void serializeTypedContents(Object[] value,
                          com.fasterxml.jackson.core.JsonGenerator jgen,
                          SerializerProvider provider)
                            throws IOException,
                                   com.fasterxml.jackson.core.JsonGenerationException

Throws:

IOException

com.fasterxml.jackson.core.JsonGenerationException

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)
                             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 StdSerializer<Object[]>

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

Throws:

JsonMappingException

_findAndAddDynamic

protected final JsonSerializer<Object> _findAndAddDynamic(PropertySerializerMap map,
                                        Class<?> type,

                                        SerializerProvider provider)
                                                   throws JsonMappingException

Throws:

JsonMappingException
