Method Details

forType

public static JsonDeserializer<?> forType(Class<?> rawType)

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 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

_concat

protected abstract T _concat(T oldValue,
 T newValue)

Since:

2.9

handleSingleElementUnwrapped

protected abstract T handleSingleElementUnwrapped(JsonParser p,
 DeserializationContext ctxt)
                                           throws IOException

Throws:

IOException

withResolved

protected abstract PrimitiveArrayDeserializers<?> withResolved(NullValueProvider nuller,
 Boolean unwrapSingle)

Since:

2.9

_constructEmpty

protected abstract T _constructEmpty()

logicalType

public LogicalType 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 class JsonDeserializer<T>

Returns:

Logical type of values this deserializer produces, if known; null if not

supportsUpdate

public Boolean supportsUpdate(DeserializationConfig config)

Description copied from class: JsonDeserializer

Introspection method that may be called to see whether deserializer supports update of an existing value (aka "merging") or not. Return value should either be Boolean.FALSE if update is not supported at all (immutable values); Boolean.TRUE if update should usually work (regular POJOs, for example), or null if this is either not known, or may sometimes work.

Information gathered is typically used to either prevent merging update for property (either by skipping, if based on global defaults; or by exception during deserializer construction if explicit attempt made) if Boolean.FALSE returned, or inclusion if Boolean.TRUE is specified. If "unknown" case (null returned) behavior is to exclude property if global defaults used; or to allow if explicit per-type or property merging is defined.

Default implementation returns null to allow explicit per-type or per-property attempts.

Overrides:

supportsUpdate in class JsonDeserializer<T>

getEmptyAccessPattern

public AccessPattern getEmptyAccessPattern()

Description copied from class: JsonDeserializer

This method may be called in conjunction with calls to JsonDeserializer.getEmptyValue(DeserializationContext), to check whether it needs to be called just once (static values), or each time empty value is needed.

Overrides:

getEmptyAccessPattern in class JsonDeserializer<T>

getEmptyValue

public Object getEmptyValue(DeserializationContext ctxt)
                     throws JsonMappingException

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 as JsonDeserializer.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 class JsonDeserializer<T>

Throws:

JsonMappingException

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 class StdDeserializer<T>

typeDeserializer - Deserializer to use for handling type information

Throws:

IOException

deserialize

public T deserialize(JsonParser p,
 DeserializationContext ctxt,
 T existing)
              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:

deserialize in class JsonDeserializer<T>

Throws:

IOException

handleNonArray

protected T handleNonArray(JsonParser p,
 DeserializationContext ctxt)
                    throws IOException

Throws:

IOException

_failOnNull

protected void _failOnNull(DeserializationContext ctxt)
                    throws IOException

Throws:

IOException
