public final class ByteObjectHashMap.KeysContainer extends java.lang.Object implements ByteLookupContainer
Constructor and Description |
---|
KeysContainer() |
Modifier and Type | Method and Description |
---|---|
void |
clear()
Removes all elements from this collection.
|
boolean |
contains(byte e)
Lookup a given element in the container.
|
<T extends BytePredicate> |
forEach(T predicate)
Applies a
predicate to container elements as long, as the
predicate returns true . |
<T extends ByteProcedure> |
forEach(T procedure)
Applies a
procedure to all container elements. |
boolean |
isEmpty()
Shortcut for
size() == 0 . |
java.util.Iterator<ByteCursor> |
iterator()
Returns an iterator to a cursor traversing the collection.
|
void |
release()
Removes all elements from the collection and additionally releases any
internal buffers.
|
int |
removeAll(byte e)
Removes all occurrences of
e from this collection. |
int |
removeAll(ByteLookupContainer c)
Default implementation uses a predicate for removal.
|
int |
removeAll(BytePredicate predicate)
Removes all elements in this collection for which the given predicate
returns
true . |
int |
retainAll(ByteLookupContainer c)
Default implementation uses a predicate for retaining.
|
int |
retainAll(BytePredicate predicate)
Default implementation redirects to
ByteCollection.removeAll(BytePredicate) and
negates the predicate. |
int |
size()
Return the current number of elements in this container.
|
byte[] |
toArray()
Default implementation of copying to an array.
|
java.lang.String |
toString()
Convert the contents of this container to a human-friendly string.

.public <T extends ByteProcedure> T forEach(T procedure)
ByteContainer
procedure
to all container elements. Returns the
argument (any subclass of ByteProcedure
. 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 ByteContainer
public <T extends BytePredicate> T forEach(T predicate)

to container elements as long, as the
predicate returns true
. The iteration is interrupted
otherwise.forEach

public java.util.Iterator<ByteCursor> iterator()
ByteContainer
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); }
