Modifier	Constructor and Description
protected	ContainerSerializer(Class<?> t, boolean dummy) Alternate constructor that is (alas!) needed to work around kinks of generic type handling

Method Summary

Modifier and Type	Method and Description
protected abstract ContainerSerializer<?>	_withValueTypeSerializer(TypeSerializer vts) 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.
abstract JsonSerializer<?>	getContentSerializer() 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.
abstract JavaType	getContentType() Accessor for finding declared (static) element type for type this serializer is used for.
protected boolean	hasContentTypeAnnotation(SerializerProvider provider, BeanProperty property) Deprecated. Since 2.7: should not be needed; should be enough to see if type has 'isStatic' modifier
abstract boolean	hasSingleElement(T value) Method called to determine if the given value (of type handled by this serializer) contains exactly one element.
ContainerSerializer<?>	withValueTypeSerializer(TypeSerializer vts) Factory(-like) method that can be used to construct a new container serializer that uses specified TypeSerializer for decorating contained values with additional type information.

ContainerSerializer

protected ContainerSerializer(Class<T> t)

ContainerSerializer

protected ContainerSerializer(JavaType fullType)

Since:

2.5

ContainerSerializer

protected ContainerSerializer(Class<?> t,
                              boolean dummy)

Alternate constructor that is (alas!) needed to work around kinks of generic type handling

Parameters:

t -

ContainerSerializer

protected ContainerSerializer(ContainerSerializer<?> src)

Method Detail

withValueTypeSerializer

public ContainerSerializer<?> withValueTypeSerializer(TypeSerializer vts)

Factory(-like) method that can be used to construct a new container serializer that uses specified TypeSerializer for decorating contained values with additional type information.

Parameters:

vts - Type serializer to use for contained values; can be null, in which case 'this' serializer is returned as is

Returns:

Serializer instance that uses given type serializer for values if that is possible (or if not, just 'this' serializer)

getContentType

public abstract JavaType getContentType()

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

getContentSerializer

public abstract JsonSerializer<?> getContentSerializer()

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 getContentType() and SerializerProvider.findContentValueSerializer(edu.internet2.middleware.grouperClientExt.com.fasterxml.jackson.databind.JavaType, edu.internet2.middleware.grouperClientExt.com.fasterxml.jackson.databind.BeanProperty).

hasSingleElement

public abstract boolean hasSingleElement(T value)

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).

Note, too, that as of now (2.9) this method is only called by serializer itself; and specifically is not used for non-array/collection types like Map or Map.Entry instances.

_withValueTypeSerializer

protected abstract ContainerSerializer<?> _withValueTypeSerializer(TypeSerializer vts)

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.

hasContentTypeAnnotation

@Deprecated
protected boolean hasContentTypeAnnotation(SerializerProvider provider,
                                                       BeanProperty property)

Deprecated. Since 2.7: should not be needed; should be enough to see if type has 'isStatic' modifier

Helper method used to encapsulate logic for determining whether there is a property annotation that overrides element type; if so, we can and need to statically find the serializer.

Since:

2.1
