Title: properties
Post by: kwasposer on July 03, 2020, 05:53:11 pm
SYSML
I ve got a block_1 in a BDD. Added some propertie_1 to it by drag&drop.

Now i created an IBD, enable the visibility in Features/Parts and Properties.

Now my propertie_1 is visible as "box" insight the block_1. Than I delete them, because I want them to be visible as list below :properties. This function is enable in the Compartment Visibility of block_1.

1) What I dont understand, that this is not working all the time? I do not have this Compartment Visibility :properties available as option. What can I do? I even restartet my model, which cannot be a solution anyway.

2) I added an Initial value to the propertie_1. Can I have a list of strings visible in the Initial_value? I tried with <memo>, but did not help in this case.

Hi,
if you expect to see the property as list in the frame of you IBD, this will not work. The compartment visibility relates the blocks shown on a BDD.
The same is valid for the initial value. This you will see in the BDD only.

Thanks, some examples

1) I am not able to list these Properties as shown in my bottom picture. Or this option :properties is not available. Only after some restarts of EA, it will be. I do not want them as box visualized. It is the same block, same properties same procedure:

2) I m looking for a solution two add two properties called subscribe: String1, String2

Now, somehow it works. Magic - I dont know, why.

But still my <<publish>> property is not visible, even so :properties is enabled in the compartment view. You need lots of patience to work with EA :(

what is  the difference between Property (Part) and Property and Attribute? Unfortunately all of this is not explained here C:\Program Files (x86)\Sparx Systems\User Guide\modeling\pastingfromthetree.html

An attribute is something resulting in a piece of memory. It can be a pointer (reference to an object) or some primitive like an integer. A property is something that can be either a simple attribute or something derived from a class operation (you will have these property getter/setter operations). A part is more tricky. It represents an instance of a class. Parts are used to show ports defined for a class. These ports are then called slots. Basically you can achieve the same result with a simple property. But parts are bound stronger to the class containing them (those are mine!).

For details you need to read UML 2.5 pp. 184 where you also can find a couple of examples.
