Class StaticListSerializerBase<T extends java.util.Collection<?>>

    • Method Detail

      • _withResolved

        public abstract JsonSerializer<?> _withResolved​(BeanProperty prop,
                                                java.lang.Boolean unwrapSingle)
        Since:
        2.9

      • createContextual

        public JsonSerializer<?> createContextual​(SerializerProvider serializers,
                                          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:
        serializers - 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

      • isEmpty

        public boolean isEmpty​(SerializerProvider provider,
                       T 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.

        NOTE: replaces JsonSerializer.isEmpty(Object), which was deprecated in 2.5

        Overrides:
        isEmpty in class JsonSerializer<T extends java.util.Collection<?>>

      • getSchema

        public JsonNode getSchema​(SerializerProvider provider,
                          java.lang.reflect.Type typeHint)
        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<T extends java.util.Collection<?>>
        Parameters:
        provider - The serializer provider.
        typeHint - A hint about the type.
        Returns:
        Json-schema for this serializer.

      • serializeWithType

        public abstract void serializeWithType​(T value,
                                       JsonGenerator g,
                                       SerializerProvider provider,
                                       TypeSerializer typeSer)
                                throws java.io.IOException
        Description copied from class: JsonSerializer
        Method that can be called to ask implementation to serialize values of type this serializer handles, using specified type serializer for embedding necessary type information.

        Default implementation will throw UnsupportedOperationException to indicate that proper type handling needs to be implemented.

        For simple datatypes written as a single scalar value (JSON String, Number, Boolean), implementation would look like: 

          // note: method to call depends on whether this type is serialized as JSON scalar, object or Array!
  typeSer.writeTypePrefixForScalar(value, gen);
  serialize(value, gen, provider);
  typeSer.writeTypeSuffixForScalar(value, gen);
        and implementations for type serialized as JSON Arrays or Objects would differ slightly, as START-ARRAY/END-ARRAY and START-OBJECT/END-OBJECT pairs need to be properly handled with respect to serializing of contents.
        Overrides:
        serializeWithType in class JsonSerializer<T extends java.util.Collection<?>>
        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.
        typeSer - Type serializer to use for including type information
        Throws:
        java.io.IOException
