StdDeserializationContext

public StdDeserializationContext(DeserializationConfig config,
                         JsonParser jp,

getDeserializerProvider

public DeserializerProvider getDeserializerProvider()

从类复制的说明: DeserializationContext

Returns provider that can be used for dynamically locating other deserializers during runtime.

覆盖:

getDeserializerProvider 在类中 DeserializationContext

getParser

public JsonParser getParser()

Method for accessing the currently active parser. May be different from the outermost parser when content is buffered.

Use of this method is discouraged: if code has direct access to the active parser, that should be used instead.

指定者:

getParser 在类中 DeserializationContext

findInjectableValue

public Object findInjectableValue(Object valueId,
                         BeanProperty forProperty,

指定者:

findInjectableValue 在类中 DeserializationContext

leaseObjectBuffer

public final ObjectBuffer leaseObjectBuffer()

从类复制的说明: DeserializationContext

Method that can be used to get access to a reusable ObjectBuffer, useful for efficiently constructing Object arrays and Lists. Note that leased buffers should be returned once deserializer is done, to allow for reuse during same round of deserialization.

指定者:

leaseObjectBuffer 在类中 DeserializationContext

returnObjectBuffer

public final void returnObjectBuffer(ObjectBuffer buf)

从类复制的说明: DeserializationContext

Method to call to return object buffer previously leased with DeserializationContext.leaseObjectBuffer().

指定者:

returnObjectBuffer 在类中 DeserializationContext

参数:

buf - Returned object buffer

getArrayBuilders

public final ArrayBuilders getArrayBuilders()

从类复制的说明: DeserializationContext

Method for accessing object useful for building arrays of primitive types (such as int[]).

指定者:

parseDate

public Date parseDate(String dateStr)
               throws IllegalArgumentException

从类复制的说明: DeserializationContext

Convenience method for parsing a Date from given String, using currently configured date format (accessed using MapperConfig.getDateFormat()).

Implementation will handle thread-safety issues related to date formats such that first time this method is called, date format is cloned, and cloned instance will be retained for use during this deserialization round.

指定者:

parseDate 在类中 DeserializationContext

抛出:

IllegalArgumentException

constructCalendar

public Calendar constructCalendar(Date d)

从类复制的说明: DeserializationContext

Convenience method for constructing Calendar instance set to specified time, to be modified and used by caller.

指定者:

constructCalendar 在类中 DeserializationContext

handleUnknownProperty

public boolean handleUnknownProperty(JsonParser jp,

                                     JsonProcessingException

Method deserializers can call to inform configured DeserializationProblemHandlers of an unrecognized property.

指定者:

handleUnknownProperty 在类中 DeserializationContext

返回:

True if there was a configured problem handler that was able to handle the proble

抛出:

IOException
