Entities and Windows


Definitions and Uses

SDL

The SDL Analyzer has the ability to generate files containing SDL cross references. See the Analyzer command described in Set-Xref, and the Organizer's Analyzer option described in Generate a cross reference file. These files use a textual format that is human readable; the purpose of the Index Viewer is to provide a means to take advantage of this information in the graphical environment. SDL icons are used when displaying the contents of the files in a graphical way.

MSC

In previous versions, the Message Sequence Chart Editor featured the generation of MSC cross references. These entities had properties that were similar to SDL cross references. Where possible, a direct mapping from MSC to the corresponding SDL concept were made. A few concepts were added so that all information of interest could be extracted from an MSC.

MSC icons identify the various MSC entities graphically, and are supported for backward compatibility reasons.

SDL Icons

Each type of SDL entity has a unique name and icon used in the Index Viewer. The different SDL diagram types use the same icon and type name as in the Organizer's Main window. For other types of entities, the following icons and names are used:

Icon Name

OPERATOR

PACKAGE_INTERFACE

CHANNEL

SIGNALROUTE

GATE

INPUT

OUTPUT

CONNECTION

CREATE

TASK

SIGNAL

SIGNALLIST

GENERATOR

FPAR; PROCESS_PARAM, PROCEDURE_PARAM (actual param.)

STATE

NEXTSTATE

TIMER

LABEL (in-connector, out-connector)

INSTANTIATION

SET

USE

INHERITS

JOIN

STATE_LIST

ATLEAST

DECISION

SAVE

DCL; VARIABLE

NEWTYPE; SYNTYPE; SORT

SYNONYM

RESET

IMPORT; IMPORT_DEF (i.e. Imported)

LITERAL

VIEW; VIEW_DEF (i.e. Viewed)

REMOTE_PROCEDURE

REMOTE_VARIABLE

SIGNALSET

ACTIVE

TRANS_OPTION (i.e. transition option)

EXPORT

ENAB_COND (i.e. enabling condition)

CONT_SIGNAL (i.e. continuous signal)

NUMBER_INST (i.e. number of instances)

EXPORTED_PROCEDURE

(PROCEDURE) CALL

REFERENCE

FIELD

Unknown symbol type. Used for diagrams when the type of the diagram for some reason could not be determined.

MSC Icons

Each type of MSC entity has a unique name and icon used in the Index Viewer. The MSC diagram uses the same icon as in the Organizer's Main window. For other types of entities, the following icons and names are used:

Icon Name

CONDITION

CREATE of instance

INPUT of message

INSTANCE head

OUTPUT of message

RESET of timer

SET of timer

STOP of process

TIMEOUT (expire of timer)

Unknown symbol type. Used for diagrams when the type of the diagram for some reason could not be determined.
