| Methods Summary |
|---|
| public void | add(OffsettedItem item)Adds an item to this instance. This will in turn tell the given item
that it has been added to this instance. It is invalid to add the
same item to more than one instance, nor to add the same items
multiple times to a single instance.
throwIfPrepared();
try {
if (item.getAlignment() > getAlignment()) {
throw new IllegalArgumentException(
"incompatible item alignment");
}
} catch (NullPointerException ex) {
// Elucidate the exception.
throw new NullPointerException("item == null");
}
items.add(item);
|
| public T | get(T item)Gets an item which was previously interned.
throwIfNotPrepared();
OffsettedItem result = interns.get(item);
if (result != null) {
return (T) result;
}
throw new NoSuchElementException(item.toString());
|
| public int | getAbsoluteItemOffset(Item item){@inheritDoc}
OffsettedItem oi = (OffsettedItem) item;
return oi.getAbsoluteOffset();
|
| public T | intern(T item)Interns an item in this instance, returning the interned instance
(which may not be the one passed in). This will add the item if no
equal item has been added.
throwIfPrepared();
OffsettedItem result = interns.get(item);
if (result != null) {
return (T) result;
}
add(item);
interns.put(item, item);

| public java.util.Collection | items(){@inheritDoc}
return items;
|
| public void | placeItems()Places all the items in this instance at particular offsets. This
will call {@link OffsettedItem#place} on each item. If an item
does not know its write size before the call to {@code place},
it is that call which is responsible for setting the write size.
This method may only be called once per instance; subsequent calls
will throw an exception.

| public void | writeIndexAnnotation(com.android.dexgen.util.AnnotatedOutput out, ItemType itemType, java.lang.String intro)Writes an index of contents of the items in this instance of the
given type. If there are none, this writes nothing. If there are any,
then the index is preceded by the given intro string.
