public class BuilderBasedDeserializer
extends BeanDeserializerBase

Class that handles deserialization using a separate Builder class, which is used for data binding and produces actual deserialized value at the end of data binding.

Note on implementation: much of code has been copied from BeanDeserializer; there may be opportunities to refactor this in future.

Method Details

unwrappingDeserializer

public JsonDeserializer<Object> unwrappingDeserializer(NameTransformer unwrapper)

Description copied from class: JsonDeserializer

Method that will return deserializer instance that is able to handle "unwrapped" value instances If no unwrapped instance can be constructed, will simply return this object as-is.

Default implementation just returns 'this' indicating that no unwrapped variant exists

Specified by:

unwrappingDeserializer in class BeanDeserializerBase

withObjectIdReader

public BeanDeserializerBase withObjectIdReader(ObjectIdReader oir)

Specified by:

withObjectIdReader in class BeanDeserializerBase

withByNameInclusion

public BeanDeserializerBase withByNameInclusion(Set<String> ignorableProps,
 Set<String> includableProps)

Specified by:

withByNameInclusion in class BeanDeserializerBase

withIgnoreAllUnknown

public BeanDeserializerBase withIgnoreAllUnknown(boolean ignoreUnknown)

Specified by:

withIgnoreAllUnknown in class BeanDeserializerBase

withBeanProperties

public BeanDeserializerBase withBeanProperties(BeanPropertyMap props)

Description copied from class: BeanDeserializerBase

Mutant factory method that custom sub-classes must override; not left as abstract to prevent more drastic backwards compatibility problems.

Overrides:

withBeanProperties in class BeanDeserializerBase

asArrayDeserializer

protected BeanDeserializerBase asArrayDeserializer()

Description copied from class: BeanDeserializerBase

Fluent factory for creating a variant that can handle POJO output as a JSON Array. Implementations may ignore this request if no such input is possible.

Specified by:

asArrayDeserializer in class BeanDeserializerBase

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 BeanDeserializerBase

finishBuild

protected Object finishBuild(DeserializationContext ctxt,
 Object builder)
                      throws IOException

Throws:

IOException

deserialize

public Object deserialize(JsonParser p,
 DeserializationContext ctxt)
                   throws IOException

Main deserialization method for bean-based objects (POJOs).

Specified by:

deserialize in class JsonDeserializer<Object>

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:

IOException

deserialize

public Object deserialize(JsonParser p,
 DeserializationContext ctxt,
 Object value)
                   throws IOException

Secondary deserialization method, called in cases where POJO instance is created as part of deserialization, potentially after collecting some or all of the properties to set.

Overrides:

deserialize in class JsonDeserializer<Object>

Throws:

IOException

deserializeFromObject

public Object deserializeFromObject(JsonParser p,
 DeserializationContext ctxt)
                             throws IOException

General version used when handling needs more advanced features.

Specified by:

deserializeFromObject in class BeanDeserializerBase

Throws:

IOException

_deserializeUsingPropertyBased

protected Object _deserializeUsingPropertyBased(JsonParser p,
 DeserializationContext ctxt)
                                         throws IOException

Method called to deserialize bean using "property-based creator": this means that a non-default constructor or factory method is called, and then possibly other setters. The trick is that values for creator method need to be buffered, first; and due to non-guaranteed ordering possibly some other properties as well.

Specified by:

_deserializeUsingPropertyBased in class BeanDeserializerBase

Returns:

Builder instance constructed

Throws:

IOException

_deserialize

protected final Object _deserialize(JsonParser p,
 DeserializationContext ctxt,
 Object builder)
                             throws IOException

Throws:

IOException

_deserializeFromArray

protected Object _deserializeFromArray(JsonParser p,
 DeserializationContext ctxt)
                                throws IOException

Description copied from class: StdDeserializer

Helper method that allows easy support for array-related coercion features: checks for either empty array, or single-value array-wrapped value (if coercion enabled by CoercionConfigs (since 2.12), and either reports an exception (if no coercion allowed), or returns appropriate result value using coercion mechanism indicated.

This method should NOT be called if Array representation is explicitly supported for type: it should only be called in case it is otherwise unrecognized.

NOTE: in case of unwrapped single element, will handle actual decoding by calling StdDeserializer._deserializeWrappedValue(edu.internet2.middleware.grouperClientExt.com.fasterxml.jackson.core.JsonParser, edu.internet2.middleware.grouperClientExt.com.fasterxml.jackson.databind.DeserializationContext), which by default calls JsonDeserializer.deserialize(JsonParser, DeserializationContext).
