Method Detail

extractAttribute

protected void extractAttribute(String decl)

For decls like "String foo" or "char *foo32[3]" compute the ID and type declarations. Also handle "int x=3" and 'T t = new T("foo")' but if the separator is ',' you cannot use ',' in the initvalue. AttributeScope.addAttributes takes care of the separation so we are free here to use from '=' to end of string as the expression. Set name, type, initvalue, and full decl instance vars.

toString
