public Class MapSerializer

Overrides tools.jackson.databind.ser.std.StdSerializer.acceptJsonFormatVisitor.

Implements tools.jackson.databind.jsonFormatVisitors.JsonFormatVisitable.acceptJsonFormatVisitor.

Doc from tools.jackson.databind.ser.std.StdSerializer.acceptJsonFormatVisitor.

Default implementation specifies no format. This behavior is usually overriden by custom serializers.

@Override

Overrides tools.jackson.databind.ValueSerializer.createContextual.

Doc from tools.jackson.databind.ValueSerializer.createContextual.

Method called to see if a different (or differently configured) serializer is needed to serialize values of specified property (or, for root values, in which case `null` is passed). 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.

Note that method is only called once per POJO property, and for the first usage as root value serializer; it is not called for every serialization, as doing that would have significant performance impact; most serializers cache contextual instances for future use.

@Override

Implements abstract tools.jackson.databind.ser.std.StdContainerSerializer.getContentSerializer.

Doc from tools.jackson.databind.ser.std.StdContainerSerializer.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 tools.jackson.databind.SerializationContext#findContentValueSerializer.

Annotations

@Override

Implements abstract tools.jackson.databind.ser.std.StdContainerSerializer.getContentType.

Doc from tools.jackson.databind.ser.std.StdContainerSerializer.getContentType.

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

Annotations

@Override

Accessor for currently assigned key serializer. Note that this may return null during construction of MapSerializer: depedencies are resolved during createContextual method (which can be overridden by custom implementations), but for some dynamic types, it is possible that serializer is only resolved during actual serialization.

Implements abstract tools.jackson.databind.ser.std.StdContainerSerializer.hasSingleElement.

Doc from tools.jackson.databind.ser.std.StdContainerSerializer.hasSingleElement.

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

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

Annotations

@Override

Implements abstract tools.jackson.databind.ser.std.StdContainerSerializer.isEmpty.

Doc from tools.jackson.databind.ValueSerializer.isEmpty.

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.

Annotations

@Override

Implements abstract tools.jackson.databind.ser.std.StdSerializer.serialize.

Doc from tools.jackson.databind.ValueSerializer.serialize.

Method that can be called to ask implementation to serialize values of type this serializer handles.

Annotations

@Override

General-purpose serialization for contents, where we do not necessarily know the value serialization, but we do know that no value suppression is needed (which simplifies processing a bit)

Method called to serialize fields, when the value type is statically known, so that value serializer is passed and does not need to be fetched from provider.

Helper method used when we have a JSON Filter to use AND contents are "any properties" of a POJO.

Parameters

bean:Object

Enclosing POJO that has any-getter used to obtain "any properties"

Helper method used when we have a JSON Filter to use for potentially filtering out Map entries.

Serialization method called when exclusion filtering needs to be applied.

General-purpose serialization for contents without writing object type. Will suppress, filter and use custom serializers.

Overrides tools.jackson.databind.ValueSerializer.serializeWithType.

Doc from tools.jackson.databind.ValueSerializer.serializeWithType.

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);

Annotations

@Override

Mutant factory for constructing an instance with different inclusion strategy for content (Map values).

Overrides tools.jackson.databind.ValueSerializer.withFilterId.

Doc from tools.jackson.databind.ValueSerializer.withFilterId.

Mutant factory method that is called if contextual configuration indicates that a specific filter (as specified by filterId) is to be used for serialization.

Default implementation simply returns this; sub-classes that do support filtering will need to create and return new instance if filter changes.
