How Java™ names are aliased

When you give a part a name, that name must be a valid Java™ identifier, except that if you are using VisualAge® Generator compatibility mode, you can use a hyphen (-), a number sign (#), or an at sign (@) in a part name, as long as it is not the first character in a part name.

If you choose a name for your part that is the same as a Java™ keyword, or a name that contains a dollar sign ($), hyphen, number sign, at sign, or underscore, the part name you have chosen will not match the name used in the generated output. This is because Java™ reserves the use of these symbols for its own use. An aliasing mechanism in EGL automatically appends an underscore to each part name that is the same as a Java™ keyword. If you specify a name that contains one or more dollar signs, hyphens, number signs, at signs, or underscores, the aliasing mechanism replaces each symbol with a numeric string representing the Unicode value of the replaced symbol, as follows:

$ _0024
- _002d
@ _0040
# _0023
_ _005f

For example, if you named a variable class, it would be changed to the alias class_; and a variable named class_ would be changed to the alias class_005f.

The case you use to declare a part name is preserved. Programs XYZ and xyz are generated as XYZ.java and xyz.java respectively.

Note:
On Windows™ 2000/NT/XP, if you generate parts with upper case names into a directory, and later generate parts with the same name in lower case and place them in that same directory, Windows™ will overwrite the older files.

EGL package names are always converted to lower case Java™ package names.

Finally, if the name of a generated Java™ class matches the name of a class from the Java™ system package java.lang, an underscore is appended to the class name: Object becomes Object_, Error becomes Error_, and so on.
