Returns:

begin

add

@PortedFrom(file="RAutomaton.h",

public void add(RATransition trans)

add a transition from a given state

Parameters:

trans - trans

hasTopTransition

@PortedFrom(file="RAutomaton.h",
            name="hasTopTransition")
public boolean hasTopTransition()

Returns:

true iff there is a top-role transition from the state

empty

@PortedFrom(file="RAutomaton.h",
            name="empty")
public boolean empty()

Returns:

true iff there are no transitions from this state

hasEmptyTransition

@PortedFrom(file="RAutomaton.h",
            name="hasEmptyTransition")
public boolean hasEmptyTransition()

Returns:

true iff there is an empty transition from the state

print

@PortedFrom(file="RAutomaton.h",
            name="print")
public void print(LogAdapter o)

print all the transitions starting from the state FROM

Parameters:

o - o

setup

@PortedFrom(file="RAutomaton.h",
            name="setup")
public void setup(int state,
                            int nRoles,
                            boolean data)

Parameters:

state - state

nRoles - nRoles

data - data

addToExisting

@PortedFrom(file="RAutomaton.h",
            name="addToExisting")
public boolean addToExisting(RATransition trans)

add information from TRANS to existing transition between the same states.

Parameters:

trans - trans

Returns:

false if no such transition found

recognise

Returns:

true iff there is only one transition

getTransitionEnd

@PortedFrom(file="RAutomaton.h",
            name="getTransitionEnd")
public int getTransitionEnd()

Returns:

state of the 1st transition; used for singletons
