Method Detail

put

short put(char key,
        short value)

Place a given key and value in the container.

Returns:

The value previously stored under the given key in the map is returned.

addTo

short addTo(char key,
          short additionValue)

An equivalent of calling

  putOrAdd(key, additionValue, additionValue);
 

Parameters:

key - The key of the value to adjust.

additionValue - The value to put or add to the existing value if key exists.

Returns:

Returns the current value associated with key (after changes).

putOrAdd

short putOrAdd(char key,
             short putValue,
             short additionValue)

Trove-inspired API method. A logical equivalent of the following code (but does not update #lastSlot):

  if (containsKey(key))
  {
      short v = (short) (lget() + additionValue);
      lset(v);
      return v;
  }
  else
  {
     put(key, putValue);
     return putValue;
  }
 

Parameters:

key - The key of the value to adjust.

putValue - The value to put if key does not exist.

additionValue - The value to add to the existing value if key exists.

Returns:

Returns the current value associated with key (after changes).

get

short get(char key)

Returns:

Returns the value associated with the given key or the default value for the key type, if the key is not associated with any value. Important note: For primitive type values, the value returned for a non-existing key may not be the default value of the primitive type (it may be any value previously assigned to that slot).

getOrDefault

short getOrDefault(char key,
                 short defaultValue)

Returns:

Returns the value associated with the given key or the provided default value if the key is not associated with any value.

putAll

int putAll(CharShortAssociativeContainer container)

Puts all keys from another container to this map, replacing the values of existing keys, if such keys are present.

Returns:

Returns the number of keys added to the map as a result of this call (not previously present in the map). Values of existing keys are overwritten.

putAll

int putAll(java.lang.Iterable<? extends CharShortCursor> iterable)

Puts all keys from an iterable cursor to this map, replacing the values of existing keys, if such keys are present.

Returns:

Returns the number of keys added to the map as a result of this call (not previously present in the map). Values of existing keys are overwritten.

remove

short remove(char key)

Remove all values at the given key. The default value for the key type is returned if the value does not exist in the map.

equals

boolean equals(java.lang.Object obj)

Compares the specified object with this set for equality. Returns true if and only if the specified object is also a CharShortMap and both objects contains exactly the same key-value pairs.

Overrides:

equals in class java.lang.Object

hashCode

int hashCode()

Overrides:

hashCode in class java.lang.Object

Returns:

A hash code of elements stored in the map. The hash code is defined as a sum of hash codes of keys and values stored within the set). Because sum is commutative, this ensures that different order of elements in a set does not affect the hash code.
