public class Byte2BooleanAVLTreeMap

extends AbstractByte2BooleanSortedMap

implements Serializable, Cloneable, Byte2BooleanSortedMap

A type-specific AVL tree map with a fast, small-footprint implementation.

The iterators provided by the views of this class are type-specific bidirectional iterators. Moreover, the iterator returned by iterator() can be safely cast to a type-specific list iterator.

Method Detail

put

public final boolean put(byte k,
                         boolean v)

Description copied from interface: Byte2BooleanMap

Adds a pair to the map.

Specified by:

put in interface Byte2BooleanMap

Overrides:

put in class AbstractByte2BooleanMap

remove

public final boolean remove(byte k)

Description copied from interface: Byte2BooleanMap

Removes the mapping with the given key.

Specified by:

remove in interface Byte2BooleanMap

Overrides:

remove in class AbstractByte2BooleanMap

put

public Object put(Object ok,
                  Object ov)

Description copied from class: AbstractByte2BooleanMap

Delegates to the corresponding type-specific method, taking care of returning null on a missing key.

This method must check whether the provided key is in the map using containsKey(). Thus, it probes the map twice. Implementors of subclasses should override it with a more efficient method.

Specified by:

put in interface Map

Overrides:

put in class AbstractByte2BooleanMap

remove

public Object remove(Object ok)

Description copied from class: AbstractByte2BooleanMap

Delegates to the corresponding type-specific method, taking care of returning null on a missing key.

This method must check whether the provided key is in the map using containsKey(). Thus, it probes the map twice. Implementors of subclasses should override it with a more efficient method.

Specified by:

remove in interface Map

Overrides:

remove in class AbstractByte2BooleanMap

containsValue

public boolean containsValue(boolean v)

Description copied from class: AbstractByte2BooleanMap

Checks whether the given value is contained in AbstractByte2BooleanMap.values().

Specified by:

containsValue in interface Byte2BooleanMap

Overrides:

containsValue in class AbstractByte2BooleanMap

clear

public void clear()

Specified by:

clear in interface Map

Overrides:

clear in class AbstractByte2BooleanMap

containsKey

public boolean containsKey(byte k)

Description copied from class: AbstractByte2BooleanMap

Checks whether the given value is contained in AbstractByte2BooleanMap.keySet().

Specified by:

containsKey in interface Byte2BooleanMap

size

public int size()

Specified by:

size in interface Map

isEmpty

public boolean isEmpty()

Specified by:

get

public boolean get(byte k)

Description copied from interface: Byte2BooleanMap

Returns the value to which the given key is mapped.

Specified by:

get in interface Byte2BooleanMap

Parameters:

k - the key.

Returns:

the corresponding value, or the default return value if no value was present for the given key.

Map.get(Object)

get

public Object get(Object ok)

Description copied from class: AbstractByte2BooleanMap

Delegates to the corresponding type-specific method, taking care of returning null on a missing key.

Overrides:

get in class AbstractByte2BooleanMap

firstByteKey

public byte firstByteKey()

Specified by:

firstByteKey in interface Byte2BooleanSortedMap

SortedMap.firstKey()

lastByteKey

public byte lastByteKey()

Specified by:

Specified by:

entrySet in interface Map

keySet

public Set keySet()

Returns a type-specific sorted set view of the keys contained in this map.

In addition to the semantics of Map.keySet(), you can safely cast the set returned by this call to a type-specific sorted set interface.

Specified by:

keySet in interface Map

Overrides:

keySet in class AbstractByte2BooleanSortedMap

Returns:

a type-specific sorted set view of the keys contained in this map.

values

public Collection values()

Returns a type-specific collection view of the values contained in this map.

In addition to the semantics of Map.values(), you can safely cast the collection returned by this call to a type-specific collection interface.

Specified by:

values in interface Map

Overrides:

values in class AbstractByte2BooleanMap

Returns:

a type-specific collection view of the values contained in this map.

comparator

clone

public Object clone()

Returns a deep copy of this tree map.

This method performs a deep copy of this tree map; the data stored in the set, however, is not cloned. Note that this makes a difference only for object keys.

Returns:

a deep copy of this tree map.
