exact code being edited was:
private void buildKeyTable(Collection<Processor<K,V>> processors){
final long when = time();
processors.stream().flatMap((p) -> {
InitialSnapshot snap = new InitialSnapshot(when, p);
p.accept(snap);
return snap.getKeys()###CURSOR HERE###;
}).forEach((snap) -> {
snap.getKeys().forEach((k)->key(k).needsUpdate(when));
});
}
I had changed processors.stream().map(... to processors.stream().flatMap(...
in anticipation of writing "return snap.getKeys().stream()" instead of "return snap;" that the generator had produced
This was automatically refactored from a for(final Processor<K,V> p : processors) {...} using the gutter hint:
------------ From --------------
private void buildKeyTable(Collection<Processor<K,V>> processors){
final long when = time();
for(final Processor<K,V> p : processors){
InitialSnapshot snap = new InitialSnapshot(when, p);
p.accept(snap);
snap.getKeys().forEach((k)->key(k).needsUpdate(when));
}
}
------------- To --------------
private void buildKeyTable(Collection<Processor<K,V>> processors){
final long when = time();
processors.stream().map((p) -> {
InitialSnapshot snap = new InitialSnapshot(when, p);
p.accept(snap);
return snap;
}).forEachOrdered((snap) -> {
snap.getKeys().forEach((k)->key(k).needsUpdate(when));
});
}
------------- Mod 1 -------------
private void buildKeyTable(Collection<Processor<K,V>> processors){
final long when = time();
processors.stream().flatMap((p) -> {
InitialSnapshot snap = new InitialSnapshot(when, p);
p.accept(snap);
return snap;
}).forEach((snap) -> {
snap.getKeys().forEach((k)->key(k).needsUpdate(when));
});
}
// produces all sorts of syntax errors
---------------- To cause exception --------------
