Method Details

getValueType

public JavaType getValueType()

Description copied from class: StdDeserializer

Exact structured type this deserializer handles, if known.

Overrides:

getValueType in class StdDeserializer<T>

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>

findBackReference

public SettableBeanProperty findBackReference(String refName)

Description copied from class: JsonDeserializer

Method needed by BeanDeserializerFactory to properly link managed- and back-reference pairs.

Overrides:

findBackReference in class JsonDeserializer<T>

getContentType

public JavaType getContentType()

Accessor for declared type of contained value elements; either exact type, or one of its supertypes.

getContentDeserializer

public abstract JsonDeserializer<Object> getContentDeserializer()

Accesor for deserializer use for deserializing content values.

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

wrapAndThrow

@Deprecated
protected <BOGUS> BOGUS wrapAndThrow(Throwable t,
 Object ref,
 String key)
                              throws IOException

Deprecated.

Since 2.12.2 (since it does not get context for accessing config)

Throws:

IOException

wrapAndThrow

protected <BOGUS> BOGUS wrapAndThrow(DeserializationContext ctxt,
 Throwable t,
 Object ref,
 String key)
                              throws IOException

Helper method called by various Map(-like) deserializers when encountering a processing problem (whether from underlying parser, i/o, or something else).

Throws:

IOException

Since:

2.12.2
