Class ParsedAssignmentsInfo

java.lang.Object

org.kie.workbench.common.stunner.bpmn.client.marshall.converters.customproperties.ParsedAssignmentsInfo

public class ParsedAssignmentsInfo
extends Object

Parses and generate the AssignmentsInfo string

AssignmentsInfo represents variables, their types, and their assignments in a Task.

It has historically been represented through a delimited String. The format of such a String follows the following EBNF:

 AssignmentInfoString ::= InputDeclarations ‘|’ OutputDeclarations ‘|’ Assignments
 InputDeclarations ::= (Declaration (‘,’ Declaration)*)?
 OutputDeclarations ::= (Declaration (‘,’ Declaration)*)?
 Declaration ::= ( identifier ( ‘:’ type )? )
 Assignments ::= (Assignment (‘,’ Assignment)* )?;
 Assignment ::= InputAssignment | OutputAssignment;
 InputAssignment ::= ‘[din]’ identifier ‘->’ identifier;
 OutputAssignment ::= ‘[dout]’ identifier ‘->’ identifier;

 

Where identifier is a valid identifier, and type is a valid identifier representing a data type. Semantically, the identifiers that has been declared in an InputDeclaration or an OutputDeclaration, or in a ProcessVariable that contains this Task

The input String follows the following rules:

 |      | in | inSet | out | outSet | assignments |
 +------+----+-------+-----+--------+-------------+
 |Catch |    |       |  x  |        |      x      |
 |Throw | x  |       |     |        |      x      |
 |Other |    |  x    |     |  x     |      x      |
 +------+----+-------+-----+--------+-------------+
 

Where Other are CallActivity, Task, SubProcess.

The distinction between input/inputSet, and output/outputSet is really not necessary because we just need to know what are the inputs and what are the outputs.

Thus, we can just use one field for inputs, and one field for outputs.
