|
An attribute that reads multiple values from a file and sets
|
|
18
|
corresponding parameters in the container.
|
|
19
|
The values are in the form:
|
|
20
|
<pre>
|
|
21
|
<i>attributeName</i> = <i>value</i>
|
|
22
|
</pre>
|
|
23
|
where <code><i>variableName</i></code> is the name of the attribute
|
|
24
|
in a format suitable for {@link ptolemy.kernel.util.NamedObj#setName(String)}
|
|
25
|
(i.e., does not contain periods) and <code><i>value</i></code> is
|
|
26
|
the expression in the Ptolemy expression language.
|
|
27
|
Comments are lines that begin with the <code>#</code> character.
|
|
28
|
Each line in the file is interpreted as a separate assignment.
|
|
29
|
|
|
30
|
<p>The attributes that are created will have the same
|
|
31
|
visibility as parameters of the container of the attribute.
|
|
32
|
They are shadowed, however, by parameters of the container.
|
|
33
|
That is, if the container has a parameter with the same name
|
|
34
|
as one in the parameter set, the one in the container provides
|
|
35
|
the value to any observer.</p>
|
|
36
|
|
|
37
|
<p>If the file is modified during execution of a model, by default
|
|
38
|
this will not be noticed until the next run. If you set the
|
|
39
|
<i>checkForFileUpdates</i> parameter to <i>true</i>, then
|
|
40
|
on each prefiring of the enclosing opaque composite actor,
|
|
41
|
this parameter will check for updates of the file. Otherwise,
|
|
42
|
it will only check between runs of the model or when the file
|
|
43
|
name or URL gets changed.</p>
|
|
44
|
|
|
45
|
<p>Note that the order the parameters are created is arbitrary,
|
|
46
|
this is because we read the file in using java.util.Properties.load(),
|
|
47
|
which uses a HashMap to store the properties. We use a Properties.load()
|
|
48
|
because it provides a nice parser for the files and can read and write
|
|
49
|
values in both text and XML.</p>
