public class Float2ObjectRBTreeMap

extends AbstractFloat2ObjectSortedMap

implements Serializable, Cloneable, Float2ObjectSortedMap

A type-specific red-black 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 Object put(float k,
                        Object v)

Description copied from interface: Float2ObjectMap

Adds a pair to the map.

Specified by:

put in interface Float2ObjectMap

Overrides:

put in class AbstractFloat2ObjectMap

remove

public final Object remove(float k)

Description copied from interface: Float2ObjectMap

Removes the mapping with the given key.

Specified by:

remove in interface Float2ObjectMap

Overrides:

remove in class AbstractFloat2ObjectMap

put

public Object put(Object ok,
                  Object ov)

Description copied from class: AbstractFloat2ObjectMap

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 AbstractFloat2ObjectMap

remove

public Object remove(Object ok)

Description copied from class: AbstractFloat2ObjectMap

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 AbstractFloat2ObjectMap

containsValue

public boolean containsValue(Object v)

Description copied from class: AbstractFloat2ObjectMap

Checks whether the given value is contained in AbstractFloat2ObjectMap.values().

Specified by:

containsValue in interface Map

Overrides:

containsValue in class AbstractFloat2ObjectMap

clear

public void clear()

Specified by:

clear in interface Map

Overrides:

clear in class AbstractFloat2ObjectMap

containsKey

public boolean containsKey(float k)

Description copied from class: AbstractFloat2ObjectMap

Checks whether the given value is contained in AbstractFloat2ObjectMap.keySet().

Specified by:

containsKey in interface Float2ObjectMap

Overrides:

size

public int size()

Specified by:

isEmpty

public boolean isEmpty()

Specified by:

get

public Object get(float k)

Description copied from interface: Float2ObjectMap

Returns the value to which the given key is mapped.

Specified by:

get in interface Float2ObjectMap

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: AbstractFloat2ObjectMap

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

public float firstFloatKey()

Specified by:

firstFloatKey in interface Float2ObjectSortedMap

SortedMap.firstKey()

lastFloatKey

public float lastFloatKey()

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 AbstractFloat2ObjectSortedMap

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 AbstractFloat2ObjectMap

Returns:

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

comparator

public Comparator 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.
