  toolbus.process.ProcessExpression

Direct Known Subclasses:

Alternative, Atom, Disrupt, DynamicProcessCall, IfElse, Iteration, LeftBiasedAlternative, LetDefinition, Merge, ProcessCall, RightBiasedAlternative, Sequence

public abstract class ProcessExpression
extends java.lang.Object

ProcesssExpression represents abstract syntax operators for operators in process expressions of Tscripts. Specific operators like Sequence and Alternative are subclasses of ProcessExpression.

Field Summary

private State	first The first (entry) state for the automaton that implements this process expression.
