Method Summary

Modifier and Type	Method	Description
T	deserialize(JsonParser p, DeserializationContext ctxt, T intoValue)	Overridden to simply call deserialize() method that does not take value to update, since scalar values are usually non-mergeable.
Object	deserializeWithType(JsonParser p, DeserializationContext ctxt, TypeDeserializer typeDeserializer)	Base implementation that does not assume specific type inclusion mechanism.
AccessPattern	getEmptyAccessPattern()	This method may be called in conjunction with calls to ValueDeserializer.getEmptyValue(DeserializationContext), to check whether it needs to be called just once (static values), or each time empty value is needed.
AccessPattern	getNullAccessPattern()	This method may be called in conjunction with calls to ValueDeserializer.getNullValue(DeserializationContext), to check whether it needs to be called just once (static values), or each time empty value is needed.
LogicalType	logicalType()	Method for accessing logical type of values this deserializer produces.
Boolean	supportsUpdate(DeserializationConfig config)	By default assumption is that scalar types cannot be updated: many are immutable values (such as primitives and wrappers)

Method Details

logicalType

public LogicalType logicalType()

Description copied from class: ValueDeserializer

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 ValueDeserializer<T>

Returns:

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

supportsUpdate

public Boolean supportsUpdate(DeserializationConfig config)

By default assumption is that scalar types cannot be updated: many are immutable values (such as primitives and wrappers)

Overrides:

supportsUpdate in class ValueDeserializer<T>

getNullAccessPattern

public AccessPattern getNullAccessPattern()

Description copied from class: ValueDeserializer

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

Default implementation indicates that the "null value" to use for input null does not vary across uses so that ValueDeserializer.getNullValue(DeserializationContext) need not be called more than once per deserializer instance. This information may be used as optimization.

Specified by:

getNullAccessPattern in interface NullValueProvider

Overrides:

getNullAccessPattern in class ValueDeserializer<T>

getEmptyAccessPattern

public AccessPattern getEmptyAccessPattern()

Description copied from class: ValueDeserializer

This method may be called in conjunction with calls to ValueDeserializer.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 ValueDeserializer<T>

deserializeWithType

public Object deserializeWithType(JsonParser p,
 DeserializationContext ctxt,
 TypeDeserializer typeDeserializer)
                           throws JacksonException

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:

JacksonException

deserialize

public T deserialize(JsonParser p,
 DeserializationContext ctxt,
 T intoValue)
              throws JacksonException

Overridden to simply call deserialize() method that does not take value to update, since scalar values are usually non-mergeable.

Overrides:

deserialize in class ValueDeserializer<T>

Throws:

JacksonException
