Class Data<T>

java.lang.Object

io.fluxzero.common.api.Data<T>

Type Parameters:

T - the type of the value held in this container

All Implemented Interfaces:

SerializedObject<T>

public class Data<T>
extends Object
implements SerializedObject<T>

A generic container for holding a value along with serialization metadata such as type, revision, and format.

This class is used extensively throughout Fluxzero to represent serialized or intermediate values (e.g.: JsonNode), often as part of SerializedMessage, SerializedDocument, or key-value entries.

Field Summary

Fields

Modifier and Type	Field	Description
static final String	DOCUMENT_FORMAT	Custom format identifier for document data used in SerializedDocument.
static final String	JSON_FORMAT	Standard media type for JSON data.

Constructor Summary

Constructors

Constructor	Description
Data(Supplier<T> value, String type, int revision, String format)	Constructs a Data instance with a Supplier to support lazy access.
Data(T value, String type, int revision)	Constructs a Data instance without a specific format (defaults to JSON).
Data(T value, String type, int revision, String format)	Constructs a Data instance with a fixed value and full metadata.

Method Summary

Modifier and Type	Method	Description
Data<T>	data()	Returns this instance (for SerializedObject compatibility).
boolean	equals(Object o)
String	getFormat()	Returns the effective format for the data, defaulting to JSON_FORMAT if format is null or "json".
T	getValue()	Returns the deserialized value.
int	hashCode()
<M> Data<M>	map(ThrowingFunction<T,M> mapper)	Transforms the value using a custom mapping function, while preserving serialization metadata.
Data<T>	withData(Data<T> data)	Replaces this instance with another Data object.

Constructor Details

Data

@ConstructorProperties({"value","type","revision","format"})
public Data(T value,
 String type,
 int revision,
 String format)

Constructs a Data instance with a fixed value and full metadata.

Data

public Data(T value,
 String type,
 int revision)

Constructs a Data instance without a specific format (defaults to JSON).

Data

public Data(Supplier<T> value,
 String type,
 int revision,
 String format)

Constructs a Data instance with a Supplier to support lazy access.

Method Details

getValue

public T getValue()

Returns the deserialized value. This may trigger lazy loading via the supplier.

Returns:

the deserialized object

getFormat

public String getFormat()

Returns the effective format for the data, defaulting to JSON_FORMAT if format is null or "json".

equals

public boolean equals(Object o)

Overrides:

equals in class Object

hashCode

public int hashCode()

Overrides:

hashCode in class Object

data

public Data<T> data()

Returns this instance (for SerializedObject compatibility).

Specified by:

data in interface SerializedObject<T>

Returns:

the serialized payload

withData

public Data<T> withData(Data<T> data)

Replaces this instance with another Data object. This method simply returns the provided argument (identity transform).

Specified by:

withData in interface SerializedObject<T>

Parameters:

data - the new serialized payload

Returns:

a new SerializedObject instance. May be this if unchanged

map

public <M> Data<M> map(ThrowingFunction<T,M> mapper)

Transforms the value using a custom mapping function, while preserving serialization metadata.

Type Parameters:

M - result type after mapping

Parameters:

mapper - transformation function that may throw an exception

Returns:

a new Data<M> with the mapped value and original serialization metadata
