| Methods Summary |
|---|
| public final void | close()Indicates that this iterator is no longer needed and that any associated resources
may be released (such as a SQLite cursor).
if (mIsClosed) {
throw new IllegalStateException("closing when already closed");
}
mIsClosed = true;
mCursor.close();
|
| public abstract Entity | getEntityAndIncrementCursor(android.database.Cursor cursor)Returns the entity that the cursor is currently pointing to. This must take care to advance
the cursor past this entity. This will never be called if the cursor is at the end.
|
| public final boolean | hasNext()Returns whether there are more elements to iterate, i.e. whether the
iterator is positioned in front of an element.
if (mIsClosed) {
throw new IllegalStateException("calling hasNext() when the iterator is closed");
}
return !mCursor.isAfterLast();
|
| public Entity | next()Returns the next object in the iteration, i.e. returns the element in
front of the iterator and advances the iterator by one position.
if (mIsClosed) {
throw new IllegalStateException("calling next() when the iterator is closed");
}
if (!hasNext()) {
throw new IllegalStateException("you may only call next() if hasNext() is true");
}
try {
return getEntityAndIncrementCursor(mCursor);
} catch (RemoteException e) {
throw new RuntimeException("caught a remote exception, this process will die soon", e);
}
|
| public void | remove()
throw new UnsupportedOperationException("remove not supported by EntityIterators");
|
| public final void | reset()
if (mIsClosed) {
throw new IllegalStateException("calling reset() when the iterator is closed");
}
mCursor.moveToFirst();
