Constructor Details

DefaultJsonDeserializer

public DefaultJsonDeserializer(@NonNull
 IBoundDefinitionModelAssembly definition)

Construct a new JSON deserializer that will parse the bound class identified by the classBinding.

Parameters:

definition - the bound class information for the Java type this deserializer is operating on

Method Details

resetFactory

protected final void resetFactory()

For use by subclasses to reset the underlying JSON factory when an important change has occurred that will change how the factory produces a JsonParser.

configurationChanged

protected void configurationChanged(IMutableConfiguration<DeserializationFeature<?>> config)

newFactoryInstance

@NonNull
protected com.fasterxml.jackson.core.JsonFactory newFactoryInstance()

Get a JSON factory instance.

This method can be used by sub-classes to create a customized factory instance.

Returns:

the factory

getJsonFactory

@NonNull
protected com.fasterxml.jackson.core.JsonFactory getJsonFactory()

Get the parser factory associated with this deserializer.

Returns:

the factory instance

newJsonParser

@NonNull
protected final com.fasterxml.jackson.core.JsonParser newJsonParser(@NonNull
 Reader reader)
                                                             throws IOException

Using the managed JSON factory, create a new JSON parser instance using the provided reader.

Parameters:

reader - the reader for the parser to read data from

Returns:

the new parser

Throws:

IOException - if an error occurred while creating the parser

deserializeToNodeItemInternal

protected INodeItem deserializeToNodeItemInternal(@NonNull
 Reader reader,
 @NonNull
 URI documentUri)
                                           throws IOException

Description copied from class: AbstractDeserializer

This abstract method delegates parsing to the concrete implementation.

Specified by:

deserializeToNodeItemInternal in class AbstractDeserializer<CLASS extends IBoundObject>

Parameters:

reader - the reader instance to read data from

documentUri - the URI of the document that is being read

Returns:

a new node item containing the read contents

Throws:

IOException - if an error occurred while reading data from the stream

deserializeToValueInternal

public CLASS deserializeToValueInternal(@NonNull
 Reader reader,
 @NonNull
 URI documentUri)
                                 throws IOException

Specified by:

deserializeToValueInternal in class AbstractDeserializer<CLASS extends IBoundObject>

Throws:

IOException

getBindingContext

@NonNull
protected IBindingContext getBindingContext()

Retrieve the binding context associated with the serializer.

Returns:

the binding context

getDefinition

@NonNull
protected IBoundDefinitionModelAssembly getDefinition()

Retrieve the bound class information associated with the assembly that the serializer/deserializer will write/read data from.

Returns:

the class binding for the Module assembly

getConfiguration

@NonNull
protected IMutableConfiguration<DeserializationFeature<?>> getConfiguration()

Get the current configuration of the serializer/deserializer.

Returns:

the configuration

isFeatureEnabled

public boolean isFeatureEnabled(DeserializationFeature<?> feature)

Specified by:

isFeatureEnabled in interface IConfiguration<T extends IConfigurationFeature<?>>
