There are tree kinds of nodes: <B>initial states</B>, (normal)
225
<B>states</B> and <B>decision points</B>.
226
All nodes should have mutually unique names.
227
Nameless states, also called <B>transitory states</B>, are not permitted.<A NAME="5354"> </A>
228
<B>Non-deterministic</B> state transition diagrams are permitted.
231
An initial state can have one or more initialization actions.
232
You can add an action by selecting the initial state, and click
233
on or near the arrow on top of the box. When an edit cursor
234
appears at the right side of the arrow, you can type in the actions.
235
Each line of text will be considered as a separate action. If you stop
236
editing, the actions will be placed at the right side of the arrow and
237
the texts become left aligned. The arrow will be resized to accommodate
238
the height of the texts and on top of the actions a horizontal separator
239
line will be drawn. Only when the initial state
240
has actions then the separator line is drawn.
241
Note that these actions are in this notational convention
242
part of the initial state <I>node</I>, whereas the other actions (and events)
243
of a diagram are as a notational convention part of an <I>edge</I>.

5.1.3 Transitions, Events and Actions
251
Transitions are drawn as arrows. They do not have a single editable name
252
label like most of the other line or arrow types in TCM.
253
Instead they have a distinct event label and an arbitrary number of
254
action labels. The action labels each occupy exactly one line of text;
255
the event label can contain multiple lines.
256
The event and the actions are separated by a horizontal <B>separator
257
line</B><A NAME="5363"> </A>. When a transition is created, a separator
258
line will also be created and it will be positioned near
259
where a name label would normally be positioned. When the transition
260
line segment near the separator is drawn vertically, the separator is
261
by default connected to the right side of that line segment. When the
262
segment is drawn horizontally, the separator is by default positioned
263
somewhat above the line. See figure <A HREF="usersguidenode7.html#DefaultSTDSeparators">5.2</A> for the
264
two default positions.

284
If you click for editing a bit above the separator line, an
285
edit cursor appears and you can enter an event string.
286
When you stop editing, the event string will be positioned above
287
the separator line and the separator line will be resized, if necessary.
290
If you click for editing a bit below the separator, an edit cursor
291
appears there and you can enter a list of actions. Each line of text will
292
become a separate action. If you stop editing, the actions will become
293
left aligned and, if necessary, the separator line will be resized.
294
When the transition line segment is horizontal and the separator is
295
positioned above the segment, all labels are moved up so that they are all
296
positioned above the line. See figure <A HREF="usersguidenode7.html#STDEventAndActions">5.3</A> for an example
297
diagram with actions and events.

317
It is possible to drag the separator line together with the
318
event and action labels. There are two different sorts of
319
movements possible. You are advised to experiment with this.
323
<DD><B>Move it to another line segment</B>. You do this by selecting
324
the transition and click for editing on the desired transition segment.
325
The separator line and the existing event and action labels are
326
moved to that line segment. When you stop editing, the separator will
327
remain in that line segment.
328
Summarizing: to move it to a different segment, empty the selection
329
and then double click the desired segment.
331
<DD><B>Move within a line segment</B>. Drag with button-1
332
the separator or one of the labels to the desired position. The final
333
position is determined by the direction of the transition line segment.
335
<LI>If the line segment is more or less horizontal, you can freely
336
move the separator and labels from left to right. But you can only move
337
the separator up and down to two predefined positions: either
338
all labels are positioned entirely above the line segment or
339
all labels are positioned entirely below the line segment.
341
<LI>If the line segment is more or less vertical, you can freely
342
move the separator and labels up and down the segment, but you
343
can only move the separator left and right to two predefined positions:
344
either all labels are entirely positioned at the left side of
345
the line segment or all labels are entirely positioned at the
346
right of the line segment.
349
The automatic positioning of labels looks best when the segments
350
are horizontal or vertical. When the transition arrow segments are
351
diagonal or curved, then label
352
positioning still works but sometimes the result does not look
353
as great as figure <A HREF="usersguidenode7.html#STDEventAndActions">5.3</A>.

An activity diagram is a special case of a state diagram in which most
399
states are action states or subactivity states, and most transitions are
400
completion transitions. The purpose of an activity diagram is to focus on
401
flows driven by internal processing (as opposed to external events).

644
TPSD has just one special type of node, called Process and
645
one type of edge called Empty edge (see figure <A HREF="usersguidenode7.html#PSRepresentations">5.9</A>).
646
The process node is represented by a box. In the
647
top right corner of the process node box, a process operator can be specified.
648
You edit this operator by selecting the box and then click in the
649
top right corner. You go into edit mode then and the operator is typed in as
650
a single character. See figure <A HREF="usersguidenode7.html#PSOperators">5.10</A> for the different operators.

5.3.2 The Process Tree
799
TPSD is a bit different from the other existing TCM diagram editors
800
because in TPSD the layout (representation) is
801
significant for the meaning of the diagram. So TPSD
802
has to make sure that there is always a one-one relationship
803
between each node instance and its representing shape instance.
804
Therefore, duplicate shapes cannot be made in TPSD.
805
During editing, TPSD enforces that the graph is a set of undirected
806
trees. It has the constraint that an edge can only be added to the
807
graph when the resulting graph would not contain a cycle.
808
This constraint is also implemented for the tree editors
809
(chapter <A HREF="usersguidenode10.html#TreeEditing">8</A>).
812
In TPSD, the highest box in the drawing area represents the
813
root of the tree, which is called the <B>main root</B>.<A NAME="5602"> </A><A NAME="5603"> </A>
814
This is the process node whose representing box has the smallest y-coordinate.
815
The <B>main tree</B><A NAME="5605"> </A> is the tree that is connected to the main root.
818
Each process node has a set of children that is ordered from left to right.
819
The ordering of the children is determined by the position of
820
the shapes in the drawing area <A NAME="tex2html99"
821
HREF="#foot5606"><SUP>5.1</SUP></A>.
824
The <B>Update Sequence Labels</B><A NAME="5608"> </A> commands
825
in a submenu of the TPSD View menu make it possible to show the process
826
sequence numbers in the lower right corners of the boxes.
827
The <B>show no sequence labels</B> command makes all the sequence numbers invisible.
828
The <B>update action sequences</B> command draws the sequence numbers of all
829
actions. <B>Actions</B><A NAME="5612"> </A> are the leaf nodes of the tree,
830
excluding the ``quit'' boxes.
831
See figure <A HREF="usersguidenode7.html#ProcessExample">5.11</A> for a PSD with numbered actions.
832
The <B>update process sequences</B> command draws sequence numbers in all process nodes.
833
Each parent receives a sequence number that is one higher than the highest
834
number amongst its children.
835
Note that the sequence numbers are not updated automatically when you edit the diagram.
836
The labels are only recalculated and updated when you perform an update
837
sequence labels command again. However, when you save the PSD to file,
838
updating sequence labels is called implicitly.

5.3.3 Constraint Checking</A>
864
The Check Diagram command in the Diagram menu checks that
865
the tree is a syntactically correct JSD process structure diagram.
866
Because of the immediately enforced constraints, Check Diagram assumes
867
that there are no duplicate nodes and no cycles.
868
In figure <A HREF="usersguidenode7.html#PSConstraints">5.12</A> all immediately and soft constraints are

There are two node types and three node shape types. Process graph roots
912
have their name label written on top of a downwards pointing arrow.
913
In general the process graph roots are named after the process
914
graph document, but in upper case letters. By default a process graph
915
is named <TT>UNTITLED</TT>. Process graph nodes have two node shape representations.
916
They can be small unnamed circles or larger rounded boxes which can
917
contain a name label. Process graph nodes are connected by event edges.

5.5.2 Interactions</A>
1194
Interactions are drawn as any other line type in TCM.
1195
In addition to the standard line types, interactions also have an arbitrary number
1196
of message labels located at the opposite side of the name area of the link.
1199
On creation of an interaction an initial dummy message will be created, consisting of a
1200
default message text ("<code>edit this</code>") followed by a message arrow.

In this way message directions can be added easy without having to switch

E.g. adding two messages to an interaction: <BR>

5.6 The StateChart Diagram Editor (TSCD)
1301
Statechart diagrams describe all the possible states a particular object
1302
can get into and how the object's state changes as a result of events
1303
that reach the object.
1306
In contrast to most editors, TSCD starts in the hierarchical document mode.
1307
To select a node, click near any visible part in the node, for example
1308
on the inner side of the border.

Drawing an <I>and-</I>state requires special attention.
1469
An <I>and-</I>state is divided into substates by dashed lines.
1470
You can draw <I>and</I> lines using the middle mouse button,
1471
like you would draw edges between different nodes.
1472
TSCD includes a feature that automatically adds intermediary points to the and
1473
line<A NAME="tex2html109"
1474
HREF="#foot5907"><SUP>5.2</SUP></A>
1475
Unfortunately, TSCD is not able to move or resize the <I>and</I> line with its
1476
intermediary points automatically
1477
when you move or resize the <I>and-</I>state node.
1478
To move an <I>and-</I>state, always also select the <I>and</I> lines.
1479
After resizing an <I>and-</I>state,
1480
you have to readjust the intermediary points in the <I>and</I> lines.
1483
See figure <A HREF="usersguidenode7.html#SCExample">5.20</A> for an example diagram with an <I>and-</I>state.

<DD>More precisely: the order
1508
of the children is determined by the x-coordinates of the end points on
1509
the parent side of the edges between the parent and
1510
the children. This sounds a bit complex, but this includes the common left
1511
to right ordering with straight edges.

1517
is needed because a line from a node to itself always has to have at
1518
least two intermediary points.
1519
The intermediary points help in determining where on the border the and
1520
line needs to be attached.
