JsonDeserializer.None
Modifier and Type | Field and Description |

_valueClass
Type of values this deserializer handles: sometimes
exact types, other time most specific supertype of
types deserializer handles (which may be as generic
as
Object in some case) |

---|---|
protected T |
_deserializeFromEmpty(com.fasterxml.jackson.core.JsonParser jp,
DeserializationContext ctxt)
Helper method that may be used to support fallback for Empty String / Empty Array
non-standard representations; usually for things serialized as JSON Objects.
|
protected boolean |
_hasTextualNull(String value)
Helper method called to determine if we are seeing String value of
"null", and, further, that it should be coerced to null just like
null token.

_isNegInf(String text) |

_parseShortPrimitive(com.fasterxml.jackson.core.JsonParser jp,
DeserializationContext ctxt) |
protected String |
_parseString(com.fasterxml.jackson.core.JsonParser jp,
DeserializationContext ctxt)
Helper method used for accessing String value, if possible, doing
necessary conversion or throwing exception as necessary.
|
Object |
deserializeWithType(com.fasterxml.jackson.core.JsonParser jp,
DeserializationContext ctxt,
TypeDeserializer typeDeserializer)
Base implementation that does not assume specific type
inclusion mechanism.
|
protected JsonDeserializer<?> |
findConvertingContentDeserializer(DeserializationContext ctxt,
BeanProperty prop,
JsonDeserializer<?> existingDeserializer)
Helper method that can be used to see if specified property has annotation
indicating that a converter is to be used for contained values (contents
of structured types; array/List/Map values)
|
protected JsonDeserializer<Object> |
findDeserializer(DeserializationContext ctxt,
JavaType type,
BeanProperty property)
Helper method used to locate deserializers for properties the
type this deserializer handles contains (usually for properties of
bean types)
|
Class<?> |
getValueClass()
Deprecated.
Since 2.3 use
handledType() instead |
JavaType |
getValueType()
Exact structured type deserializer handles, if known.
|
Class<?> |
handledType()
Method for accessing type of values this deserializer produces.
|
protected void |
handleUnknownProperty(com.fasterxml.jackson.core.JsonParser jp,
DeserializationContext ctxt,
Object instanceOrClass,
String propName)
Method called to deal with a property that did not map to a known
Bean property.
|
protected boolean |
isDefaultDeserializer(JsonDeserializer<?> deserializer)
Method that can be called to determine if given deserializer is the default
deserializer Jackson uses; as opposed to a custom deserializer installed by
a module or calling application.
|
protected boolean |
isDefaultKeyDeserializer(KeyDeserializer keyDeser) |
protected static double |
parseDouble(String numStr)
Helper method for encapsulating calls to low-level double value parsing; single place
just because we need a work-around that must be applied to all calls.

same as returning Object.class
would; that is, that
nothing is known about handled type.
