DoubleIndexedContainer.public java.util.Iterator<DoubleCursor> iterator()
The iterator is implemented as a cursor and it returns the same cursor
instance on every call to Iterator.next() (to avoid boxing of
primitive types). To read the current list's value (or index in the list)
use the cursor's public fields. An example is shown below.
for (DoubleCursor<double> c : container) {
System.out.println("index=" + c.index + " value=" + c.value);
}
iterator in interface DoubleContaineriterator in interface java.lang.Iterable<DoubleCursor>public <T extends DoubleProcedure> T forEach(T procedure)
procedure to all container elements. Returns the
argument (any subclass of DoubleProcedure. This lets the caller to
call methods of the argument by chaining the call (even if the argument is
an anonymous type) to retrieve computed values, for example (IntContainer):
int count = container.forEach(new IntProcedure() {
int count; // this is a field declaration in an anonymous class.
public void apply(int value) {
count++;
}
}).count;

otherwise.forEach in interface DoubleContainerpublic <T extends DoublePredicate> T forEach(T predicate, int fromIndex, int toIndex)

double.
The elements are copied from the argument to the internal buffer.
