Method Detail

handledType

public java.lang.Class<?> handledType()

Description copied from class: JsonDeserializer

Method for accessing type of values this deserializer produces. Note that this information is not guaranteed to be exact -- it may be a more generic (super-type) -- but it should not be incorrect (return a non-related type).

Default implementation will return null, which means almost same same as returning Object.class would; that is, that nothing is known about handled type.

Overrides:

handledType in class JsonDeserializer<T>

getValueClass

@Deprecated
public final java.lang.Class<?> getValueClass()

Deprecated. Since 2.3 use handledType() instead

getValueType

public JavaType getValueType()

Exact structured type this deserializer handles, if known.

getValueType

public JavaType getValueType(DeserializationContext ctxt)

Convenience method for getting handled type as JavaType, regardless of whether deserializer has one already resolved (and accessible via getValueType()) or not: equivalent to:

   if (getValueType() != null) {
        return getValueType();
   }
   return ctxt.constructType(handledType());

Since:

2.10

deserializeWithType

public java.lang.Object deserializeWithType(JsonParser p,
                                            DeserializationContext ctxt,
                                            TypeDeserializer typeDeserializer)
                                     throws java.io.IOException

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 JsonDeserializer<T>

typeDeserializer - Deserializer to use for handling type information

Throws:

java.io.IOException
