create

public static DataAttributeDef create(Class dataType,
 String key)

iWF will verify if the key has been registered for the data attribute created using this method, allowing users to create only one data attribute with the same key and data type.

Parameters:

dataType - required.

key - required. The unique key.

Returns:

a data attribute definition

createByPrefix

public static DataAttributeDef createByPrefix(Class dataType,
 String keyPrefix)

iWF now supports dynamically created data attributes with a shared prefix and the same data type. (E.g., dynamically created data attributes of type String can be named with a common prefix like: data_attribute_prefix_1: "one", data_attribute_prefix_2: "two") iWF will verify if the prefix has been registered for data attributes created using this method, allowing users to create multiple data attributes with the same prefix and data type.

Parameters:

dataType - required.

keyPrefix - required. The common prefix of a set of keys to be created later.

Returns:

a data attribute definition
