## com.fasterxml.jackson.databind.jsontype.impl
Class AsPropertyTypeSerializer

    java.lang.Object
      com.fasterxml.jackson.databind.jsontype.TypeSerializer
          com.fasterxml.jackson.databind.jsontype.impl.TypeSerializerBase
              com.fasterxml.jackson.databind.jsontype.impl.AsArrayTypeSerializer
                  com.fasterxml.jackson.databind.jsontype.impl.AsPropertyTypeSerializer

    public class AsPropertyTypeSerializer

extends AsArrayTypeSerializer

Type serializer that preferably embeds type information as an additional JSON Object property, if possible (when resulting serialization would use JSON Object). If this is not possible (for JSON Arrays, scalars), uses a JSON Array wrapper (similar to how `JsonTypeInfo.As.WRAPPER_ARRAY` always works) as a fallback.

Field Summary
`protected String` | `_typePropertyName`

Fields inherited from class com.fasterxml.jackson.databind.jsontype.impl.TypeSerializerBase
`_idResolver, _property`

Constructor Summary
`AsPropertyTypeSerializer(TypeIdResolver idRes, BeanProperty property, String propName)`

Method Summary
`AsPropertyTypeSerializer` | `forProperty(BeanProperty prop)` Method called to create contextual version, to be used for values of given property.
`String` | `getPropertyName()` Name of property that contains type information, if property-based inclusion is used.
`com.fasterxml.jackson.annotation.JsonTypeInfo.As` | `getTypeInclusion()` Accessor for type information inclusion method that serializer uses; indicates how type information is embedded in resulting JSON.
`void` | `writeCustomTypePrefixForObject(Object value, com.fasterxml.jackson.core.JsonGenerator jgen, String typeId)` Method called to write initial part of type information for given value, when it will be output as JSON Object value (not as JSON Array or scalar), using specified custom type id instead of calling `TypeIdResolver`.
`void` | `writeCustomTypeSuffixForObject(Object value, com.fasterxml.jackson.core.JsonGenerator jgen, String typeId)`
`void` | `writeTypePrefixForObject(Object value, com.fasterxml.jackson.core.JsonGenerator jgen)` Method called to write initial part of type information for given value, when it will be output as JSON Object value (not as JSON Array or scalar).
`void` | `writeTypePrefixForObject(Object value, com.fasterxml.jackson.core.JsonGenerator jgen, Class<?> type)` Alternative version of the prefix-for-object method, which is given actual type to use (instead of using exact type of the value); typically a super type of actual value type
`void` | `writeTypeSuffixForObject(Object value, com.fasterxml.jackson.core.JsonGenerator jgen)` Method called after value has been serialized, to close any scopes opened by earlier matching call to `TypeSerializer.writeTypePrefixForObject(java.lang.Object, com.fasterxml.jackson.core.JsonGenerator)`.

Field Detail

### _typePropertyName

    protected final String _typePropertyName

Constructor Detail

### AsPropertyTypeSerializer

    public AsPropertyTypeSerializer(TypeIdResolver idRes,
                                    BeanProperty property,
                                    String propName)

Method Detail

### forProperty

    public AsPropertyTypeSerializer forProperty(BeanProperty prop)

  Description copied from class: `TypeSerializer`
  Method called to create contextual version, to be used for values of given property. This may be the type itself (as is the case for bean properties), or values contained (for `Collection` or `Map` valued properties).

  Overrides:
    `forProperty` in class `AsArrayTypeSerializer`

### getPropertyName

    public String getPropertyName()

  Description copied from class: `TypeSerializer`
  Name of property that contains type information, if property-based inclusion is used.

  Overrides:
    `getPropertyName` in class `TypeSerializerBase`

### getTypeInclusion

    public com.fasterxml.jackson.annotation.JsonTypeInfo.As getTypeInclusion()

  Description copied from class: `TypeSerializer`
  Accessor for type information inclusion method that serializer uses; indicates how type information is embedded in resulting JSON.

  Overrides:
    `getTypeInclusion` in class `AsArrayTypeSerializer`

### writeTypePrefixForObject

    public void writeTypePrefixForObject(Object value,
                                         com.fasterxml.jackson.core.JsonGenerator jgen)
                                  throws IOException,
                                         com.fasterxml.jackson.core.JsonProcessingException

  Description copied from class: `TypeSerializer`
  Method called to write initial part of type information for given value, when it will be output as JSON Object value (not as JSON Array or scalar). This means that context after call must be JSON Object, meaning that caller can then proceed to output field entries.

  Overrides:
    `writeTypePrefixForObject` in class `AsArrayTypeSerializer`
  Parameters:
    `value` - Value that will be serialized, for which type information is to be written
    `jgen` - Generator to use for writing type information
  Throws:
    `IOException`
    `com.fasterxml.jackson.core.JsonProcessingException`

### writeTypePrefixForObject

    public void writeTypePrefixForObject(Object value,
                                         com.fasterxml.jackson.core.JsonGenerator jgen,
                                         Class<?> type)
                                  throws IOException,
                                         com.fasterxml.jackson.core.JsonProcessingException

  Description copied from class: `TypeSerializer`
  Alternative version of the prefix-for-object method, which is given actual type to use (instead of using exact type of the value); typically a super type of actual value type

  Overrides:
    `writeTypePrefixForObject` in class `AsArrayTypeSerializer`
  Throws:
    `IOException`
    `com.fasterxml.jackson.core.JsonProcessingException`

### writeTypeSuffixForObject

    public void writeTypeSuffixForObject(Object value,
                                         com.fasterxml.jackson.core.JsonGenerator jgen)
                                  throws IOException,
                                         com.fasterxml.jackson.core.JsonProcessingException

  Description copied from class: `TypeSerializer`
  Method called after value has been serialized, to close any scopes opened by earlier matching call to `TypeSerializer.writeTypePrefixForObject(java.lang.Object, com.fasterxml.jackson.core.JsonGenerator)`. It needs to write closing END_OBJECT marker, and any other decoration that needs to be matched.

  Overrides:
    `writeTypeSuffixForObject` in class `AsArrayTypeSerializer`
  Throws:
    `IOException`
    `com.fasterxml.jackson.core.JsonProcessingException`

    public void writeCustomTypePrefixForObject(Object value,
                                               com.fasterxml.jackson.core.JsonGenerator jgen,
                                               String typeId)
                                        throws IOException,
                                               com.fasterxml.jackson.core.JsonProcessingException

  Description copied from class: `TypeSerializer`
  Method called to write initial part of type information for given value, when it will be output as JSON Object value (not as JSON Array or scalar), using specified custom type id instead of calling `TypeIdResolver`. This means that context after call must be JSON Object, meaning that caller can then proceed to output field entries.

  Overrides:
    `writeCustomTypePrefixForObject` in class `AsArrayTypeSerializer`
  Parameters:
    `value` - Value that will be serialized, for which type information is to be written
    `jgen` - Generator to use for writing type information
    `typeId` - Exact type id to use
  Throws:
    `IOException`
    `com.fasterxml.jackson.core.JsonProcessingException`

### writeCustomTypeSuffixForObject

    public void writeCustomTypeSuffixForObject(Object value,
                                               com.fasterxml.jackson.core.JsonGenerator jgen,
