Class EnumMapDeserializer
java.lang.Object
com.fasterxml.jackson.databind.JsonDeserializer<T>
com.fasterxml.jackson.databind.deser.std.StdDeserializer<EnumMap<?,?>>
com.fasterxml.jackson.databind.deser.std.EnumMapDeserializer
- All Implemented Interfaces:
- ContextualDeserializer
public class EnumMapDeserializer
- extends StdDeserializer<EnumMap<?,?>>
- implements ContextualDeserializer
Deserializer for EnumMap
values.
Note: casting within this class is all messed up -- just could not figure out a way
to properly deal with recursive definition of "EnumMap, V>

createContextual
public JsonDeserializer<?> createContextual(DeserializationContext ctxt,
BeanProperty property)
throws JsonMappingException
- Method called to finalize setup of this deserializer,
when it is known for which property deserializer is needed for.
- Specified by:
createContextual
in interface ContextualDeserializer
- Parameters:
ctxt
- Deserialization context to access configuration, additional
deserializers that may be needed by this deserializerproperty
- 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
isCachable
public boolean isCachable()
- Because of costs associated with constructing Enum resolvers,
let's cache instances by default.
- Overrides:
isCachable
in class JsonDeserializer<EnumMap<?,?>>
deserialize
public EnumMap<?,?> 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<EnumMap<?,?>>
- Parameters:
jp
- Parsed used for reading JSON contentctxt
- 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<EnumMap<?,?>>
typeDeserializer
- Deserializer to use for handling type information
- Throws:
IOException
com.fasterxml.jackson.core.JsonProcessingException
