Method Detail

getDeserializer

public static JsonDeserializer<? extends JsonNode> getDeserializer(java.lang.Class<?> nodeClass)

Factory method for accessing deserializer for specific node type

getNullValue

public JsonNode getNullValue(DeserializationContext ctxt)

Description copied from class: JsonDeserializer

Method that can be called to determine value to be used for representing null values (values deserialized when JSON token is JsonToken.VALUE_NULL). Usually this is simply Java null, but for some types (especially primitives) it may be necessary to use non-null values.

Since version 2.6 (in which the context argument was added), call is expected to be made each and every time a null token needs to be handled.

Default implementation simply returns null.

Overrides:

getNullValue in class JsonDeserializer<JsonNode>

getNullValue

@Deprecated
public JsonNode getNullValue()

Deprecated.

Overrides:

getNullValue in class JsonDeserializer<JsonNode>

deserialize

public JsonNode deserialize(com.fasterxml.jackson.core.JsonParser p,
                            DeserializationContext ctxt)
                     throws java.io.IOException

Implementation that will produce types of any JSON nodes; not just one deserializer is registered to handle (in case of more specialized handler). Overridden by typed sub-classes for more thorough checking

Specified by:

deserialize in class JsonDeserializer<JsonNode>

Parameters:

p - Parsed used for reading JSON content

ctxt - Context that can be used to access information about this deserialization activity.

Returns:

Deserialized value

Throws:

java.io.IOException
