Enum Variables.SerializationDataFormats

java.lang.Object

java.lang.Enum<Variables.SerializationDataFormats>

org.camunda.bpm.engine.variable.Variables.SerializationDataFormats

All Implemented Interfaces:

Serializable, Comparable<Variables.SerializationDataFormats>, SerializationDataFormat

Enclosing class:

Variables

public static enum Variables.SerializationDataFormats
extends Enum<Variables.SerializationDataFormats>
implements SerializationDataFormat

A set of builtin serialization dataformat constants. These constants can be used to specify how java object variables should be serialized by the process engine:

 CustomerData customerData = new CustomerData();
 // ...
 ObjectValue customerDataValue = Variables.objectValue(customerData)
   .serializationDataFormat(Variables.SerializationDataFormats.JSON)
   .create();

 execution.setVariable("someVariable", customerDataValue);
 

Note that not all of the formats provided here are supported out of the box.

Enum Constant Detail

JAVA

public static final Variables.SerializationDataFormats JAVA

The Java Serialization Data format. If this data format is used for serializing an object, the object is serialized using default Java Serializable.

The process engine provides a serializer for this dataformat out of the box.

JSON

public static final Variables.SerializationDataFormats JSON

The Json Serialization Data format. If this data format is used for serializing an object, the object is serialized as Json text.

NOTE: the process does NOT provide a serializer for this dataformat out of the box. If you want to serialize objects using the Json dataformat, you need to provide a serializer. The optinal camunda Spin process engine plugin provides such a serializer.

XML

public static final Variables.SerializationDataFormats XML

The Xml Serialization Data format. If this data format is used for serializing an object, the object is serialized as Xml text.

NOTE: the process does NOT provide a serializer for this dataformat out of the box. If you want to serialize objects using the Xml dataformat, you need to provide a serializer. The optinal camunda Spin process engine plugin provides such a serializer.

Method Detail

values

public static Variables.SerializationDataFormats[] values()

Returns an array containing the constants of this enum type, in the order they are declared. This method may be used to iterate over the constants as follows:

for (Variables.SerializationDataFormats c : Variables.SerializationDataFormats.values())
    System.out.println(c);

Returns:

an array containing the constants of this enum type, in the order they are declared

valueOf

public static Variables.SerializationDataFormats valueOf(String name)

Returns the enum constant of this type with the specified name. The string must match exactly an identifier used to declare an enum constant in this type. (Extraneous whitespace characters are not permitted.)

Parameters:

name - the name of the enum constant to be returned.

Returns:

the enum constant with the specified name

Throws:

IllegalArgumentException - if this enum type has no constant with the specified name

NullPointerException - if the argument is null

getName

public String getName()

Description copied from interface: SerializationDataFormat

The name of the dataformat. Example: "application/json"

Specified by:

getName in interface SerializationDataFormat

Returns:

the name of the dataformat.
