Class FlatVariableScope

java.lang.Object

org.kie.workbench.common.stunner.bpmn.client.marshall.converters.fromstunner.properties.FlatVariableScope

All Implemented Interfaces:

VariableScope

public class FlatVariableScope
extends Object
implements VariableScope

A flat variable scope, where no nesting information is used.

In a flat scope there is no nesting. E.g.:

Process P defines variables x,y

• SubProcess P1 nested in P defines P1_x, P2_y
• SubProcess P2 nested in P defines P2_x

The FlatScope contains:

• x
• y
• P1_x
• P1_y
• P2_x

Also, P1 may refer to x, y, P1_x, P1_y, but also to P2_x, P2_y

In a flat scope, names can easily clash, but it's simple to implement (it's a Map).

In future versions we might want to implement a more refined Scope notion with nesting; in this case, P1 may refer to x, y P1_x, P1_y, but NOT to P2_x, P2_y, because P2 does not nest in P1
