Constructor Detail

AbstractByte2CharSortedMap.KeySet

protected AbstractByte2CharSortedMap.KeySet()
Method Detail

contains

public boolean contains(byte k)
Specified by:
contains in interface ByteCollection
Overrides:
contains in class AbstractByteCollection
See Also:
Collection.contains(Object)

size

public int size()
Specified by:
size in interface Collection<Byte>
Specified by:
size in interface Set<Byte>
Specified by:
size in class AbstractCollection<Byte>

clear

public void clear()
Specified by:
clear in interface Collection<Byte>
Specified by:
clear in interface Set<Byte>
Overrides:
clear in class AbstractCollection<Byte>

comparator

public ByteComparator comparator()
Description copied from interface: ByteSortedSet
Returns the comparator associated with this sorted set, or null if it uses its elements' natural ordering.

Note that this specification strengthens the one given in SortedSet.comparator().

See Also:
SortedSet.comparator()

firstByte

public byte firstByte()
See Also:
SortedSet.first()

lastByte

public byte lastByte()
See Also:
SortedSet.last()

headSet

public ByteSortedSet headSet(byte to)
See Also:
SortedSet.headSet(Object)

tailSet

public ByteSortedSet tailSet(byte from)
See Also:
SortedSet.tailSet(Object)

subSet

public ByteSortedSet subSet(byte from,
                            byte to)
See Also:
SortedSet.subSet(Object,Object)

iterator

public ByteBidirectionalIterator iterator(byte from)
Description copied from interface: ByteSortedSet
Returns a type-specific BidirectionalIterator on the elements in this set, starting from a given element of the domain (optional operation).

This method returns a type-specific bidirectional iterator with given starting point. The starting point is any element comparable to the elements of this set (even if it does not actually belong to the set). The next element of the returned iterator is the least element of the set that is greater than the starting point (if there are no elements greater than the starting point, hasNext() will return false). The previous element of the returned iterator is the greatest element of the set that is smaller than or equal to the starting point (if there are no elements smaller than or equal to the starting point, hasPrevious() will return false).

Note that passing the last element of the set as starting point and calling previous() you can traverse the entire set in reverse order.

Parameters:
from - an element to start from.
Returns:
a bidirectional iterator on the element in this set, starting at the given element.

iterator

public ByteBidirectionalIterator iterator()
Description copied from interface: ByteCollection
Returns a type-specific iterator on the elements of this collection.

Note that this specification strengthens the one given in Iterable.iterator(), which was already strengthened in the corresponding type-specific class, but was weakened by the fact that this interface extends Collection.

Specified by:
iterator in interface ByteCollection
Specified by:
iterator in interface ByteIterable
Specified by:
iterator in interface ByteSet
Specified by:
iterator in interface ByteSortedSet
Specified by:
iterator in interface Iterable<Byte>
Specified by:
iterator in interface Collection<Byte>
Specified by:
iterator in interface Set<Byte>
Specified by:
iterator in class AbstractByteSortedSet
Returns:
a type-specific iterator on the elements of this collection.
