, both have the same size, and all corresponding
pairs of elements at the same index are equal. In other words, two indexed
containers are defined to be equal if they contain the same elements in the same
order.
Note that, unlike in List
, containers may be of different types and still
return true
from FloatIndexedContainer.equals(java.lang.Object)
. This may be dangerous if you use
different hash functions in two containers, but don't override the default
implementation of FloatIndexedContainer.equals(java.lang.Object)
. It is the programmer's responsibility to
enforcing these contracts properly.

public java.util.Iterator<FloatCursor> 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 (FloatCursor<float> c : container) { System.out.println("index=" + c.index + " value=" + c.value); }

to all container elements. Returns the argument (any
subclass of FloatProcedure

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;
