## com.fasterxml.jackson.databind.deser.std
Class EnumSetDeserializer

    java.lang.Object
      com.fasterxml.jackson.databind.JsonDeserializer<T>
          com.fasterxml.jackson.databind.deser.std.StdDeserializer<EnumSet<?>>
              com.fasterxml.jackson.databind.deser.std.EnumSetDeserializer

All Implemented Interfaces:
  ContextualDeserializer

    public class EnumSetDeserializer

extends StdDeserializer<EnumSet<?>>
implements ContextualDeserializer

Standard deserializer for `EnumSet`s.

Note: casting within this class is all messed up -- just could not figure out a way to properly deal with recursive definition of "EnumSet, V>

Method Summary
`JsonDeserializer<?>` | `createContextual(DeserializationContext ctxt, BeanProperty property)` Method called to see if a different (or differently configured) deserializer is needed to deserialize values of specified property.
`EnumSet<?>` | `deserialize(com.fasterxml.jackson.core.JsonParser jp, DeserializationContext ctxt)` Method that can be called to ask implementation to deserialize JSON content into the value type this serializer handles.
`Object` | `deserializeWithType(com.fasterxml.jackson.core.JsonParser jp, DeserializationContext ctxt, TypeDeserializer typeDeserializer)` Base implementation that does not assume specific type inclusion mechanism.
`boolean` | `isCachable()` Because of costs associated with constructing Enum resolvers, let's cache instances by default.

Constructor Detail

### EnumSetDeserializer

    public EnumSetDeserializer(JavaType enumType,
                               JsonDeserializer<?> deser)

Method Detail

### withDeserializer

    public EnumSetDeserializer withDeserializer(JsonDeserializer<?> deser)

### isCachable

    public boolean isCachable()

  Because of costs associated with constructing Enum resolvers, let's cache instances by default.

  Overrides:
    `isCachable` in class `JsonDeserializer<EnumSet<?>>`

### createContextual

    public JsonDeserializer<?> createContextual(DeserializationContext ctxt,
                                                BeanProperty property)
                                         throws JsonMappingException

  Description copied from interface: `ContextualDeserializer`
  Method called to see if a different (or differently configured) deserializer is needed to deserialize 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 `ContextualDeserializer`
  Parameters:
    `ctxt` - Deserialization context to access configuration, additional deserializers that may be needed by this deserializer
    `property` - Method, field or constructor parameter that represents the property (and is used to assign deserialized value). Should be available; but there may be cases where caller can not provide it and null is passed instead (in which case impls usually pass 'this' deserializer as is)
  Returns:
    Deserializer to use for deserializing values of specified property; may be this instance or a new instance.
  Throws:
    `JsonMappingException`

### deserialize

    public EnumSet<?> deserialize(com.fasterxml.jackson.core.JsonParser jp,
                                  DeserializationContext ctxt)
                           throws IOException,
                                  com.fasterxml.jackson.core.JsonProcessingException

  Description copied from class: `JsonDeserializer`
  Method that can be called to ask implementation to deserialize JSON content into the value type this serializer handles. Returned instance is to be constructed by method itself.

  Pre-condition for this method is that the parser points to the first event that is part of value to deserializer (and which is never JSON 'null' literal, more on this below): for simple types it may be the only value; and for structured types the Object start marker. Post-condition is that the parser will point to the last event that is part of deserialized value (or in case deserialization fails, event that was not recognized or usable, which may be the same event as the one it pointed to upon call).

  Note that this method is never called for JSON null literal, and thus deserializers need (and should) not check for it.

  Specified by:
    `deserialize` in class `JsonDeserializer<EnumSet<?>>`
  Parameters:
    `jp` - Parsed used for reading JSON content
    `ctxt` - Context that can be used to access information about this deserialization activity.
  Returns:
    Deserializer value
  Throws:
    `IOException`
    `com.fasterxml.jackson.core.JsonProcessingException`

### deserializeWithType

    public Object deserializeWithType(com.fasterxml.jackson.core.JsonParser jp,
                                      DeserializationContext ctxt,
                                      TypeDeserializer typeDeserializer)
                               throws IOException,
                                      com.fasterxml.jackson.core.JsonProcessingException

  Description copied from class: `StdDeserializer`
  Base implementation that does not assume specific type inclusion mechanism. Sub-classes are expected to override this method if they are to handle type information.

  Overrides:
    `deserializeWithType` in class `StdDeserializer<EnumSet<?>>`
    `typeDeserializer` - Deserializer to use for handling type information
  Throws:
    `IOException`
    `com.fasterxml.jackson.core.JsonProcessingException`
