Return the maximum number of elements this container is guaranteed to hold without reallocating.

clear()
Removes all elements from this collection.
|
boolean |
contains(long value)
Lookup a given element in the container.
|
<T extends LongPredicate> |
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. |

Returns an iterator to a cursor traversing the collection.

Removes all occurrences of
e from this collection. |

given predicate returns
true. |

public int size()
O(n) time, although implementing classes
should try to maintain the current size and return in constant time.public int capacity()
O(n) time.public boolean contains(long value)
LongContainertrue if this container has an element
equal to e.public <T extends LongProcedure> T forEach(T procedure)
LongContainerprocedure to all container elements. Returns the argument (any
subclass of LongProcedure. 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;
public <T extends LongPredicate> T forEach(T predicate)
LongContainerpredicate to container elements, as long as the predicate
returns true. The iteration is interrupted otherwise.public DoubleLongHashMap.ValuesIterator iterator()
LongContainerThe 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 (LongCursor<long> c : container) {
System.out.println("index=" + c.index + " value=" + c.value);
}
public int removeAll(long e)
e from this collection.
Indeed removes all the (key,value) pairs matching
(key ? , e) with the same e, from the map.e - Element to be removed from this collection, if present.public int removeAll(LongPredicate predicate)
true.
Indeed removes all the (key,value) pairs matching
the predicate for the values, from the map.public void clear()
public long[] toArray(long[] target)
AbstractLongCollectiontoArray in interface LongContainertoArray in class AbstractLongCollectiontarget - The target array must be large enough to hold all elements, i.e >= LongContainer.size().Copyright © 2017. All rights reserved.
