size
public int size()
Description copied from interface:ByteContainer
Return the current number of elements in this container. The time for calculating the container's size may takeO(n)
time, although implementing classes should try to maintain the current size and return in constant time.
-
isEmpty
public boolean isEmpty()
Description copied from interface:ByteContainer
Shortcut forsize() == 0
.
-
contains
public boolean contains(byte value)
Description copied from interface:ByteContainer
Lookup a given element in the container. This operation has no speed guarantees (may be linear with respect to the size of this container).- Returns:
- Returns
true
if this container has an element equal toe
.
-
forEach
public <T extends ByteProcedure> T forEach(T procedure)
Description copied from interface:ByteContainer
Applies aprocedure
to all container elements. Returns the argument (any subclass ofByteProcedure
. 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
public <T extends BytePredicate> T forEach(T predicate)
Description copied from interface:ByteContainer
Applies apredicate
to container elements as long, as the predicate returnstrue
. The iteration is interrupted otherwise.
-
iterator
public java.util.Iterator<ByteCursor> iterator()
Description copied from interface:ByteContainer
Returns an iterator to a cursor traversing the collection. The order of traversal is not defined. More than one cursor may be active at a time. The behavior of iterators is undefined if structural changes are made to the underlying collection.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 (ByteCursor<byte> c : container) { System.out.println("index=" + c.index + " value=" + c.value); }
-
removeAll
public int removeAll(byte e)
Description copied from interface:ByteCollection
Removes all occurrences ofe
from this collection.- Parameters:
e
- Element to be removed from this collection, if present.- Returns:
- The number of removed elements as a result of this call.
-
removeAll
public int removeAll(BytePredicate predicate)
Description copied from interface:ByteCollection
Removes all elements in this collection for which the given predicate returnstrue
.- Returns:
- Returns the number of removed elements.
-
clear
public void clear()
Description copied from interface:ByteCollection
Removes all elements from this collection.- See Also:
ByteCollection.release()
-
release
public void release()
Description copied from interface:ByteCollection
Removes all elements from the collection and additionally releases any internal buffers. Typically, if the object is to be reused, a simpleByteCollection.clear()
should be a better alternative since it'll avoid reallocation.- See Also:
ByteCollection.clear()
