Change subject: core: Add no-argument constructor check
......................................................................
Patch Set 1:
(3 comments)
Sorry for the delay, went completely under my radar.
Re: patterns/filters:
After rethinking it, I suggest we just drop the entire filtering concept and
opt for simplicity - EVERYTHING under common or compat should adhere to this
checkstyle, and this way we save ourselves the bugs of someone writing a class
called MyParms instead of MyParameters and breaking GWT.
If we opt to leave the filtering, I accept that FilteringAPI is not the right
way to go (as commented by Vojtec), but we should definitely fail the build if
given an illegal regex, as agreed inline.
Regardless, I have a couple mote implementation comments, inline, but nothing
there seems to major.

Line 45:
Line 46: @Override
Line 47: public void visitToken(DetailAST classDef) {
Line 48: if (!isClass(classDef) || !shouldCheckClass(classDef)) {
IIUC, the isClass check is redundant since getDefaultTokens() already ensures
you're only visiting CLASS_DEF items.
Line 49: return;
Line 50: }
Line 51:
Line 52: final DetailAST objBlock =
classDef.findFirstToken(TokenTypes.OBJBLOCK);
Line 58: if (child.getType() == TokenTypes.CTOR_DEF) {
Line 59: hasExplicitCtor = true;
Line 60: DetailAST ctorParams =
child.findFirstToken(TokenTypes.PARAMETERS);
Line 61: if (ctorParams.getChildCount() == 0) {
Line 62: hasNoArgCtor = true;
I'd just return here. But I guess it's a matter of personal style.
Line 63: break;

Line 79:
Line 80: boolean shouldCheckClass(DetailAST classDef) {
Line 81: return filterPattern != null ?
filterPattern.matcher(getFullyQualifiedClassName(classDef)).matches() : true;
filterPattern should never be null (after you change the build to fail if the
pattern does not compile), so the ternary expression here can be ommited.
