continue cannot be used outside of a loop (it isn't outside actually)
I dont understand why continue causes error here
public void clear() {
log.debug("Clearing hash");
// wow!
while( hash.size()>0 ) {
for(Map.Entry<Node,Node> entry : hash.entrySet()) {
clearingParents: {
while( entry.getKey().ups.size() > 0 ) {
for(Node node : entry.getKey().ups) {
log.debug("Clearing {}, hash size is {}", node, hash.size());
if( node.sizeUps() == 0 ) {
node.clear();
continue clearingParents;
}
else {
log.debug("was skipped since inserted");
}
}
break clearingParents;
}
}
}
}
I am using this scheme since node.clear() causes iterator to appear broken
Answer
you label an block instead of the while loop.
you can break out of a labeled block but not continue the labeled block
it doesnt make sense to continue a labeled block as it aint a loop
label your loop like below
clearingParents: while( entry.getKey().ups.size() > 0 ) {
for(Node node : entry.getKey().ups) {
log.debug("Clearing {}, hash size is {}", node, hash.size());
if( node.sizeUps() == 0 ) {
node.clear();
continue clearingParents;
}
else {
log.debug("was skipped since inserted");
}
}
break clearingParents;
}
