Overrides com.fasterxml.jackson.databind.ser.std.StdSerializer.acceptJsonFormatVisitor.

Implements com.fasterxml.jackson.databind.jsonFormatVisitors.JsonFormatVisitable.acceptJsonFormatVisitor.

Doc from com.fasterxml.jackson.databind.ser.std.StdSerializer.acceptJsonFormatVisitor.

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

Parameters

typeHint:JavaType

Doc from com.fasterxml.jackson.databind.jsonFormatVisitors.JsonFormatVisitable.acceptJsonFormatVisitor.

Type of element (entity like property) being visited

Annotations

@Override

Implements com.fasterxml.jackson.databind.ser.ContextualSerializer.createContextual.

We need to resolve actual serializer once we know the context; specifically must know type of property being serialized.

Parameters

provider:SerializerProvider

Doc from com.fasterxml.jackson.databind.ser.ContextualSerializer.createContextual.

Serializer provider to use for accessing config, other serializers

property:BeanProperty

Doc from com.fasterxml.jackson.databind.ser.ContextualSerializer.createContextual.

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:JsonSerializer<?>

Doc from com.fasterxml.jackson.databind.ser.ContextualSerializer.createContextual.

Serializer to use for serializing values of specified property; may be this instance or a new instance.

Annotations

@Override

Implements abstract com.fasterxml.jackson.databind.ser.ContainerSerializer.getContentSerializer.

Doc from com.fasterxml.jackson.databind.ser.ContainerSerializer.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 com.fasterxml.jackson.databind.SerializerProvider#findContentValueSerializer.

Annotations

@Override

Implements abstract com.fasterxml.jackson.databind.ser.ContainerSerializer.getContentType.

Doc from com.fasterxml.jackson.databind.ser.ContainerSerializer.getContentType.

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

Annotations

@Override

Implements abstract com.fasterxml.jackson.databind.ser.ContainerSerializer.hasSingleElement.

Doc from com.fasterxml.jackson.databind.ser.ContainerSerializer.hasSingleElement.

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

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.

Annotations

@Override

Overrides com.fasterxml.jackson.databind.JsonSerializer.isEmpty.

Doc from com.fasterxml.jackson.databind.JsonSerializer.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

Overrides com.fasterxml.jackson.databind.JsonSerializer.isUnwrappingSerializer.

Doc from com.fasterxml.jackson.databind.JsonSerializer.isUnwrappingSerializer.

Accessor for checking whether this serializer is an "unwrapping" serializer; this is necessary to know since it may also require caller to suppress writing of the leading property name.

Annotations

@Override

Implements com.fasterxml.jackson.databind.ser.ResolvableSerializer.resolve.

Doc from com.fasterxml.jackson.databind.ser.ResolvableSerializer.resolve.

Method called after SerializerProvider has registered the serializer, but before it has returned it to the caller. Called object can then resolve its dependencies to other types, including self-references (direct or indirect).

Note that this method does NOT return serializer, since resolution is not allowed to change actual serializer to use.

Parameters

provider:SerializerProvider

Provider that has constructed serializer this method is called on.

Annotations

@Override

Implements abstract com.fasterxml.jackson.databind.ser.std.StdSerializer.serialize.

Doc from com.fasterxml.jackson.databind.JsonSerializer.serialize.

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

Parameters

value:Object

Value to serialize; can not be null.

g:JsonGenerator

Generator used to output resulting Json content

provider:SerializerProvider

Provider that can be used to get serializers for serializing Objects value contains, if any.

Annotations

@Override

Overrides com.fasterxml.jackson.databind.JsonSerializer.serializeWithType.

Doc from com.fasterxml.jackson.databind.JsonSerializer.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);

Parameters

value:Object

Value to serialize; can not be null.

g:JsonGenerator

Generator used to output resulting Json content

provider:SerializerProvider

Provider that can be used to get serializers for serializing Objects value contains, if any.

typeSer:TypeSerializer

Type serializer to use for including type information

Annotations

@Override

Overrides com.fasterxml.jackson.databind.JsonSerializer.unwrappingSerializer.

Doc from com.fasterxml.jackson.databind.JsonSerializer.unwrappingSerializer.

Method that will return serializer instance that produces "unwrapped" serialization, if applicable for type being serialized (which is the case for some serializers that produce JSON Objects as output). If no unwrapped serializer can be constructed, will simply return serializer as-is.

Default implementation just returns serializer as-is, indicating that no unwrapped variant exists

Parameters

unwrapper:NameTransformer

Name transformation to use to convert between names of unwrapper properties

Annotations

@Override

Overrides com.fasterxml.jackson.databind.JsonSerializer.usesObjectId.

Doc from com.fasterxml.jackson.databind.JsonSerializer.usesObjectId.

Method that can be called to see whether this serializer instance will use Object Id to handle cyclic references.
