Info

Coding Style editor should be configured to react to the Tab key by inserting spaces rather than the tab character. To set up Emacs to follow the Ptolemy II indentation style, see $PTII/util/lisp/ptemacs.el. To set up Eclipse to follow the Ptolemy II indentation style, see the instructions in $PTII/doc/coding/ eclipse.htm. Long lines should be broken up into many small lines. The easiest places to break long lines are usually just before operators, with the operator appearing on the next line. Long strings can be broken up using the + operator in Java, with the + starting the next line. Continuation lines are indented by 8 characters, as in the throws clause of the constructor in figure 6.1. 6.4.3 Spaces Use a space after each comma: Right: foo(a, b); Wrong: foo(a,b); Use spaces around operators such as plus, minus, multiply, divide or equals signs, and after semicolons: Right: a = b + 1; Wrong: a=b+1; Right: for(i = 0; i < 10; i += 2) Wrong: for(i=0 ;i
Coding Style + "it does not implement Cloneable."); Note that the exception not only gives a way to identify the objects that caused the exception, but also why the exception occurred. There is no need to include in the message an identification of the “this” object passed as the first argument to the exception constructor. That object will be identified when the exception is reported to the user. If an exception is caught, be sure to use exception chaining to include the original exception. For example: String fileName = foo(); try { // Try to open the file } catch (IOException ex) { throw new IllegalActionException(this, ex, "Failed to open '" + fileName + "'"); } 6.5 Directory naming conventions Individual demonstrations should be in directories under a demo/ directory. The name of the directory, and the name of the model should match and both begin with capital letters. The demos should be capitalized so that it is possible to generate code for demonstrations. For example, the Butterfly demonstration is in sdf/demo/Butterfly/Butterfly.xml. All other directories begin with lower case letters and most consist solely of lower case letters.
