Embodiment
Below in conjunction with drawings and Examples the present invention is further described:
Embodiment one: a kind of model base icon display method based on physical modeling language comprises preprocessing process and icon display process;
Described preprocessing process is that the analytic model storehouse to the model traversal order in file and the file, generates the icon of each model during according to the loaded and displayed model bank successively, writes in the icon file;
Described icon display process is in loaded and displayed model bank process, to read in corresponding model icon according to the model traversal order from described icon file, and be shown in the model bank window.
Illustrate as follows with an illustraton of model target generative process:
The analytic model storehouse is adopted serializing " to write " mode model icon sequential write is gone into icon file in advance.
In the loaded and displayed model bank process, adopt serializing " to read " mode the model icon is read in, and be shown in the model bank window.
Illustraton of model is demarcated adopted fragment (is example with resistance R esistor):
model?Resistor＂Ideal?linear?electrical?resistor＂
extends?OnePort；
... // annotate, the description code irrelevant with the model icon replaces with suspension points, down together
annotation(......，
Coordsys(
extent＝[-100，-100；100，100])，......
)，
Icon(
Rectangle(extent＝[-70，30；70，-30]，style(
color＝3，
fillColor＝7，
fillPattern＝1))，
Line(points＝[-90，0；-70，0])，
Line(points＝[70，0；90，0])，
Text(
extent＝[-144，-60；144，-100]，
string＝＂R＝％R＂，
style(color＝0))，
Text(extent＝[-144，40；144，100]，string＝＂％name＂))，
......
)；
......
end?Resistor；
With above-mentioned code is example, and it is as follows to form illustraton of model target step:
