        public int size()
        Description copied from interface: TObjectShortMap
        Returns the number of key-value mappings in this map. If the map contains more than Integer.MAX_VALUE elements, returns Integer.MAX_VALUE.
        Specified by:
        size in interface TObjectShortMap<K>
        Returns:
        the number of key-value mappings in this map

      • isEmpty

        public boolean isEmpty()
        Description copied from interface: TObjectShortMap
        Returns true if this map contains no key-value mappings.
        Specified by:
        isEmpty in interface TObjectShortMap<K>
        Returns:
        true if this map contains no key-value mappings

      • containsKey

        public boolean containsKey(java.lang.Object key)
        Description copied from interface: TObjectShortMap
        Returns true if this map contains a mapping for the specified key. More formally, returns true if and only if this map contains a mapping for a key k such that (key==null ? k==null : key.equals(k)). (There can be at most one such mapping.)
        Specified by:
        containsKey in interface TObjectShortMap<K>
        Parameters:
        key - key whose presence in this map is to be tested
        Returns:
        true if this map contains a mapping for the specified key

      • containsValue

        public boolean containsValue(short val)
        Description copied from interface: TObjectShortMap
        Returns true if this map maps one or more keys to the specified value. More formally, returns true if and only if this map contains at least one mapping to a value v such that (value==no_entry_value ? v==no_entry_value : value.equals(v)). This operation will probably require time linear in the map size for most implementations of the Map interface.

        Note that no_entry_value is the result of TObjectShortMap.getNoEntryValue() and represents null for this map instance.

        Specified by:
        containsValue in interface TObjectShortMap<K>
        Parameters:
        val - short value whose presence in this map is to be tested
        Returns:
        true if this map maps one or more keys to the specified value

      • get

        public short get(java.lang.Object key)
        Description copied from interface: TObjectShortMap
        Returns the value to which the specified key is mapped, or null if this map contains no mapping for the key.

        More formally, if this map contains a mapping from a key k to a value v such that (key==null ? k==null : key.equals(k)), then this method returns v; otherwise it returns null. (There can be at most one such mapping.)

        If this map permits null values, then a return value of null does not necessarily indicate that the map contains no mapping for the key; it's also possible that the map explicitly maps the key to null. The containsKey operation may be used to distinguish these two cases.

        Specified by:
        get in interface TObjectShortMap<K>
        Parameters:
        key - the key whose associated value is to be returned
        Returns:
        the short value to which the specified key is mapped, or null if this map contains no mapping for the key

      • put

        public short put(K key,
                 short value)
        Description copied from interface: TObjectShortMap
        Associates the specified value with the specified key in this map (optional operation). If the map previously contained a mapping for the key, the old value is replaced by the specified value. (A map m is said to contain a mapping for a key k if and only if m.containsKey(k) would return true.)
        Specified by:
        put in interface TObjectShortMap<K>
        Parameters:
        key - key with which the specified value is to be associated
        value - an short value value to be associated with the specified key
        Returns:
        the previous value associated with key, or no_entry_value if there was no mapping for key. (A no_entry_value return can also indicate that the map previously associated null with key, if the implementation supports null values.)
        See Also:
        TObjectShortMap.getNoEntryValue()

      • remove

        public short remove(java.lang.Object key)
        Description copied from interface: TObjectShortMap
        Removes the mapping for a key from this map if it is present (optional operation). More formally, if this map contains a mapping from key k to value v such that (key==null ? k==null : key.equals(k)), that mapping is removed. (The map can contain at most one such mapping.)

        Returns the value to which this map previously associated the key, or null if the map contained no mapping for the key.

        If this map permits null values, then a return value of null does not necessarily indicate that the map contained no mapping for the key; it's also possible that the map explicitly mapped the key to null.

        The map will not contain a mapping for the specified key once the call returns.

        Specified by:
        remove in interface TObjectShortMap<K>
        Parameters:
        key - key whose mapping is to be removed from the map
        Returns:
        the previous short value associated with key, or null if there was no mapping for key.

      • putAll

        public void putAll(TObjectShortMap<? extends K> m)
        Description copied from interface: TObjectShortMap
        Put all the entries from the given map into this map.
        Specified by:
        putAll in interface TObjectShortMap<K>
        Parameters:
        m - The map from which entries will be obtained to put into this map.

      • putAll

        public void putAll(java.util.Map<? extends K,? extends java.lang.Short> map)
        Description copied from interface: TObjectShortMap
        Copies all of the mappings from the specified map to this map (optional operation). The effect of this call is equivalent to that of calling put(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 interface TObjectShortMap<K>
        Parameters:
        map - mappings to be stored in this map

      • clear

        public void clear()
        Description copied from interface: TObjectShortMap
        Removes all of the mappings from this map (optional operation). The map will be empty after this call returns.
        Specified by:
        clear in interface TObjectShortMap<K>

      • keySet

        public java.util.Set<K> keySet()
        Description copied from interface: TObjectShortMap
        Returns a Set 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 interface TObjectShortMap<K>
        Returns:
        a set view of the keys contained in this map

      • keys

        public java.lang.Object[] keys()
        Description copied from interface: TObjectShortMap
        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 interface TObjectShortMap<K>
        Returns:
        a copy of the keys of the map as an array.

      • keys

        public K[] keys(K[] array)
        Description copied from interface: TObjectShortMap
        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 interface TObjectShortMap<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

        public TShortCollection valueCollection()
        Description copied from interface: TObjectShortMap
        Returns a TShortCollection 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 TShortIterator.remove, TShortCollection.remove, removeAll, retainAll and clear operations. It does not support the add or addAll operations.
        Specified by:
        valueCollection in interface TObjectShortMap<K>
        Returns:
        a collection view of the values contained in this map

      • values

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

      • values

        public short[] values(short[] array)
        Description copied from interface: TObjectShortMap
        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 interface TObjectShortMap<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 values of the map as an array of short values.

      • equals

        public boolean equals(java.lang.Object o)
        Description copied from interface: TObjectShortMap
        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()). This ensures that the equals method works properly across different implementations of the Map interface.
        Specified by:
        equals in interface TObjectShortMap<K>
        Overrides:
        equals in class java.lang.Object
        Parameters:
        o - object to be compared for equality with this map
        Returns:
        true if the specified object is equal to this map

      • hashCode

        public int hashCode()
        Description copied from interface: TObjectShortMap
        Returns the hash code value for this map. The hash code of a map is defined to be the sum of the hash codes of each entry in the map's entrySet() view. This ensures that m1.equals(m2) implies that m1.hashCode()==m2.hashCode() for any two maps m1 and m2, as required by the general contract of Object.hashCode().
        Specified by:
        hashCode in interface TObjectShortMap<K>
        Overrides:
        hashCode in class java.lang.Object
        Returns:
        the hash code value for this map
