void |
clear()
Removes all elements from this collection.
|
boolean |
contains(int e)
Lookup a given element in the container.
|
<T extends IntPredicate> |
forEach(T predicate)
Applies a
predicate to container elements as long, as the
predicate returns true. |

forEach(T procedure)
Applies a
procedure to all container elements. |

iterator()
Returns an iterator to a cursor traversing the collection.

release()
Removes all elements from the collection and additionally releases any
internal buffers.

public boolean contains(int e)
IntContainercontains in interface IntContainercontains in interface IntLookupContainertrue if this container has an element equal to
e.public <T extends IntProcedure> T forEach(T procedure)
IntContainerprocedure to all container elements. Returns the
argument (any subclass of IntProcedure. 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;
forEach in interface IntContainerpublic <T extends IntPredicate> T forEach(T predicate)
IntContainerpredicate to container elements as long, as the
predicate returns true. The iteration is interrupted
otherwise.forEach in interface IntContainerpublic boolean isEmpty()

IntContainer
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 (IntCursor<int> c : container) {
System.out.println("index=" + c.index + " value=" + c.value);
}
