isCachable
public boolean isCachable()Description copied from class:JsonDeserializer
Method called to see if deserializer instance is cachable and usable for other properties of same type (type for which instance was created).Note that cached instances are still resolved on per-property basis, if instance implements
ResolvableDeserializer
: cached instance is just as the base. This means that in most cases it is safe to cache instances; however, it only makes sense to cache instances if instantiation is expensive, or if instances are heavy-weight.Default implementation returns false, to indicate that no caching is done.
- Overrides:
isCachable
in classJsonDeserializer<Object[]>
-
logicalType
Description copied from class:JsonDeserializer
Method for accessing logical type of values this deserializer produces. Typically used for further configuring handling of values, for example, to find which coercions are legal.- Overrides:
logicalType
in classJsonDeserializer<Object[]>
- Returns:
- Logical type of values this deserializer produces, if known;
null
if not
-
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 interfaceContextualDeserializer
- 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 cannot 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
-
getContentDeserializer
Description copied from class:ContainerDeserializerBase
Accesor for deserializer use for deserializing content values.- Specified by:
getContentDeserializer
in classContainerDeserializerBase<Object[]>
-
getEmptyAccessPattern
Description copied from class:JsonDeserializer
This method may be called in conjunction with calls toJsonDeserializer.getEmptyValue(DeserializationContext)
, to check whether it needs to be called just once (static values), or each time empty value is needed.- Overrides:
getEmptyAccessPattern
in classContainerDeserializerBase<Object[]>
-
getEmptyValue
Description copied from class:JsonDeserializer
Method called to determine value to be used for "empty" values (most commonly when deserializing from empty JSON Strings). Usually this is same asJsonDeserializer.getNullValue(edu.internet2.middleware.grouperClientExt.com.fasterxml.jackson.databind.DeserializationContext)
(which in turn is usually simply Java null), but it can be overridden for specific types. Or, if type should never be converted from empty String, method can also throw an exception.This method may be called once, or multiple times, depending on what
JsonDeserializer.getEmptyAccessPattern()
returns.Default implementation simply calls
JsonDeserializer.getNullValue(edu.internet2.middleware.grouperClientExt.com.fasterxml.jackson.databind.DeserializationContext)
and returns value.- Overrides:
getEmptyValue
in classContainerDeserializerBase<Object[]>
- Throws:
JsonMappingException
-
deserialize
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 or a FIELD_NAME.
The two possible input conditions for structured types result from polymorphism via fields. In the ordinary case, Jackson calls this method when it has encountered an OBJECT_START, and the method implementation must advance to the next token to see the first field name. If the application configures polymorphism via a field, then the object looks like the following.
{ "@class": "class name", ... }
Jackson consumes the two tokens (the @class field name and its value) in order to learn the class and select the deserializer. Thus, the stream is pointing to the FIELD_NAME for the first field after the @class. Thus, if you want your method to work correctly both with and without polymorphism, you must begin your method with:if (p.currentToken() == JsonToken.START_OBJECT) { p.nextToken(); }
This results in the stream pointing to the field name, so that the two conditions align.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.

- Parameters:
p
- Parsed used for reading JSON contentctxt
- Context that can be used to access information about this deserialization activity.- Returns:
- Deserialized value
- Throws:

deserializeWithType
public Object[] deserializeWithType(JsonParser p, DeserializationContext ctxt, TypeDeserializer typeDeserializer) throws IOException 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 classStdDeserializer<Object[]>
typeDeserializer
- Deserializer to use for handling type information- Throws:
IOException
-
deserialize
public Object[] deserialize(JsonParser p, DeserializationContext ctxt, Object[] intoValue) throws IOException Description copied from class:JsonDeserializer
Alternate deserialization method (compared to the most commonly used,JsonDeserializer.deserialize(JsonParser, DeserializationContext)
), which takes in initialized value instance, to be configured and/or populated by deserializer. Method is not necessarily used (or supported) by all types (it will not work for immutable types, for obvious reasons): most commonly it is used for Collections and Maps. It may be used both with "updating readers" (for POJOs) and when Collections and Maps use "getter as setter".Default implementation just throws
UnsupportedOperationException
, to indicate that types that do not explicitly add support do not necessarily support update-existing-value operation (esp. immutable types)- Overrides:

in classJsonDeserializer<Object[]>
- Throws:
IOException
-
deserializeFromBase64
