Class ProcessDataInfo

java.lang.Object
  wt.workflow.definer.ProcessDataInfo

All Implemented Interfaces:

Evolvable, Externalizable, NetFactor, Serializable

public class ProcessDataInfo

extends Object

implements Externalizable, NetFactor, Evolvable

The ProcessDataInfo class provides information about the structure of ProcessData sets for the generated execution objects. It associates property names (variables) with their types and is used to generate ProcessData objects. The order in which the variables occur in the process data is relevant.

Each process data info object contains a vector with variable information. This is an uniform vector of WfVariableInfo objects in which no two WfVariableInfo objects can have the same name.

Use the newProcessDataInfo static factory method(s), not the ProcessDataInfo constructor, to construct instances of this class. Instances must be constructed using the static factory(s), in order to ensure proper initialization of the instance.

Supported API: true

Extendable: false
