size
public int size()Description copied from interface:TObjectIntMap

in interfaceTObjectIntMap<K>
- Returns:
- the number of key-value mappings in this map
-
isEmpty
public boolean isEmpty()Description copied from interface:TObjectIntMap
Returns true if this map contains no key-value mappings.- Specified by:
isEmpty
in interfaceTObjectIntMap<K>
- Returns:
- true if this map contains no key-value mappings
-
containsKey
Description copied from interface:TObjectIntMap
Checks for the present of key in the keys of the map.- Specified by:
containsKey
in interfaceTObjectIntMap<K>
-
containsValue
public boolean containsValue(int value) Description copied from interface:TObjectIntMap
Checks for the presence of val in the values of the map.- Specified by:
containsValue
in interfaceTObjectIntMap<K>
-
get
Description copied from interface:TObjectIntMap
Retrieves the value for key.- Specified by:
get
in interfaceTObjectIntMap<K>
- Returns:
- the previous value associated with key, or the "no entry" value
if none was found (see
TObjectIntMap.getNoEntryValue()
).
-
put
Description copied from interface:TObjectIntMap
Inserts a key/value pair into the map.- Specified by:
put
in interfaceTObjectIntMap<K>
- Returns:
- the previous value associated with key, or the "no entry" value
if none was found (see
TObjectIntMap.getNoEntryValue()
).
-
remove
Description copied from interface:TObjectIntMap
Deletes a key/value pair from the map.- Specified by:
remove
in interfaceTObjectIntMap<K>
- Parameters:
key
- an#k#
value- Returns:
- the previous value associated with key, or the "no entry" value
if none was found (see
TObjectIntMap.getNoEntryValue()
).
-
putAll
Description copied from interface:TObjectIntMap
Copies all of the mappings from the specified map to this map (optional operation). The effect of this call is equivalent to that of callingput(k, v)
on this map once for each mapping from key k to value v in the specified map. The behavior of this operation is undefined if the specified map is modified while the operation is in progress.- Specified by:
putAll
in interfaceTObjectIntMap<K>
- Parameters:
map
- mappings to be stored in this map
-
putAll
Description copied from interface:TObjectIntMap
Put all the entries from the given map into this map.- Specified by:
putAll
in interfaceTObjectIntMap<K>
- Parameters:
map
- The map from which entries will be obtained to put into this map.
-
clear
public void clear()Description copied from interface:TObjectIntMap
Removes all of the mappings from this map (optional operation). The map will be empty after this call returns.- Specified by:
clear
in interfaceTObjectIntMap<K>
-
keySet
Description copied from interface:TObjectIntMap
Returns aSet
view of the keys contained in this map. The set is backed by the map, so changes to the map are reflected in the set, and vice-versa. If the map is modified while an iteration over the set is in progress (except through the iterator's own remove operation), the results of the iteration are undefined. The set supports element removal, which removes the corresponding mapping from the map, via the Iterator.remove, Set.remove, removeAll, retainAll, and clear operations. It does not support the add or addAll operations.- Specified by:
keySet
in interfaceTObjectIntMap<K>
- Returns:
- a set view of the keys contained in this map
-
keys
Description copied from interface:TObjectIntMap
Returns a copy of the keys of the map as an array. Changes to the array of keys will not be reflected in the map nor vice-versa.- Specified by:
keys
in interfaceTObjectIntMap<K>
- Returns:
- a copy of the keys of the map as an array.
-
keys

Returns a copy of the keys of the map as an array. Changes to the array of keys will not be reflected in the map nor vice-versa.- Specified by:
keys
in interfaceTObjectIntMap<K>
- Parameters:
array
- the array into which the elements of the list are to be stored, if it is big enough; otherwise, a new array of the same type is allocated for this purpose.- Returns:
- the keys of the map as an array.
-
valueCollection
Description copied from interface:TObjectIntMap
Returns aTIntCollection
view of the values contained in this map. The collection is backed by the map, so changes to the map are reflected in the collection, and vice-versa. If the map is modified while an iteration over the collection is in progress (except through the iterator's own remove operation), the results of the iteration are undefined. The collection supports element removal, which removes the corresponding mapping from the map, via the TIntIterator.remove, TIntCollection.remove, removeAll, retainAll and clear operations. It does not support the add or addAll operations.- Specified by:
valueCollection
in interfaceTObjectIntMap<K>
- Returns:
- a collection view of the values contained in this map
-
values
public int[] values()Description copied from interface:TObjectIntMap

values
in interfaceTObjectIntMap<K>
- Returns:
- the values of the map as an array of int values.
-
values
public int[] values(int[] array) Description copied from interface:TObjectIntMap
Returns the values of the map using an existing array. Changes to the array of values will not be reflected in the map nor vice-versa.- Specified by:
values
in interfaceTObjectIntMap<K>
- Parameters:
array

equals
Description copied from interface:TObjectIntMap
Compares the specified object with this map for equality. Returns true if the given object is also a map and the two maps represent the same mappings. More formally, two maps m1 and m2 represent the same mappings if m1.entrySet().equals(m2.entrySet()).

equals

equals

o
- object to be compared for equality with this map- Returns:
- true if the specified object is equal to this map
-

.- Specified by:
hashCode
in interfaceTObjectIntMap<K>
- Overrides:
hashCode
in classObject
