Method Details

copy

public JsonMapper copy()

Description copied from class: ObjectMapper

Method for creating a new ObjectMapper instance that has same initial configuration as this instance. Note that this also requires making a copy of the underlying JsonFactory instance.

Method is typically used when multiple, differently configured mappers are needed. Although configuration is shared, cached serializers and deserializers are NOT shared, which means that the new instance may be re-configured before use; meaning that it behaves the same way as if an instance was constructed from scratch.

Overrides:

copy in class ObjectMapper

builder

public static JsonMapper.Builder builder()

builder

public static JsonMapper.Builder builder(JsonFactory streamFactory)

rebuild

public JsonMapper.Builder rebuild()

version

public Version version()

Description copied from class: ObjectMapper

Method that will return version information stored in and read from jar that contains this class.

Specified by:

version in interface Versioned

Overrides:

version in class ObjectMapper

Returns:

Version of the component

getFactory

public JsonFactory getFactory()

Description copied from class: ObjectCodec

Accessor for finding underlying data format factory (JsonFactory) codec will use for data binding.

Overrides:

getFactory in class ObjectMapper

Returns:

Underlying JsonFactory instance

isEnabled

public boolean isEnabled(JsonReadFeature f)

isEnabled

public boolean isEnabled(JsonWriteFeature f)
