示例1: ClassImplementsProtocol
/// ClassImplementsProtocol - Checks that 'lProto' protocol
/// has been implemented in IDecl class, its super class or categories (if
/// lookupCategory is true).
bool ObjCInterfaceDecl::ClassImplementsProtocol(ObjCProtocolDecl *lProto,
bool lookupCategory,
bool RHSIsQualifiedID) {
if (!hasDefinition())
return false;
ObjCInterfaceDecl *IDecl = this;
// 1st, look up the class.
for (ObjCInterfaceDecl::protocol_iterator
PI = IDecl->protocol_begin(), E = IDecl->protocol_end(); PI != E; ++PI){
if (getASTContext().ProtocolCompatibleWithProtocol(lProto, *PI))
return true;
// This is dubious and is added to be compatible with gcc. In gcc, it is
// also allowed assigning a protocol-qualified 'id' type to a LHS object
// when protocol in qualified LHS is in list of protocols in the rhs 'id'
// object. This IMO, should be a bug.
// FIXME: Treat this as an extension, and flag this as an error when GCC
// extensions are not enabled.
if (RHSIsQualifiedID &&
getASTContext().ProtocolCompatibleWithProtocol(*PI, lProto))
return true;
}
// 2nd, look up the category.
if (lookupCategory)
