put

void put(int key,
         double value)

Parameters:

key - the key

value - the value to associate with value

putPair

default void putPair(IntDoublePair keyValuePair)

This method allows MutableIntDoubleMap the ability to add an element in the form of IntDoublePair.

Since:

9.1.0

See Also:

put(int, double)

putAll

Puts all of the key/value mappings from the specified map into this map. If this map already has a value associated with one of the keys in the map, it will be replaced with the value in map.

Parameters:

map - the map to copy into this map

updateValues

void updateValues(IntDoubleToDoubleFunction function)

Updates the values in-place.

Parameters:

function - that takes a key and its value and that returns a new value for this key

Since:

10.0

removeKey

void removeKey(int key)

Removes the mapping associated with the key, if one exists, from the map.

Parameters:

key - the key to remove

See Also:

remove(int)

remove

void remove(int key)

Removes the mapping associated with the key, if one exists, from the map.

                         double value)

Removes the mapping associated with the key, if one exists, from the map, returning the previously associated value with the key. If no mapping existed for the key, the specified default value is returned.

Parameters:

key - the key to remove

value - the default value to return if no mapping for the key exists

Returns:

the value previously associated with the key, if one existed, or value if not

getIfAbsentPut

double getIfAbsentPut(int key,
                      double value)

Retrieves the value associated with the key if one exists; if it does not, associates a value with the key.

Parameters:

key - the key

value - the value to associate with key if no such mapping exists

Returns:

the value associated with key, if one exists, or value if not

getIfAbsentPut

double getIfAbsentPut(int key,
                      DoubleFunction0 function)

Retrieves the value associated with the key if one exists; if it does not, invokes the supplier and associates the result with the key.

Parameters:

key - the key

function - the supplier that provides the value if no mapping exists for key

Returns:

the value associated with the key, if one exists, or the result of invoking function if not

getIfAbsentPutWithKey

double getIfAbsentPutWithKey(int key,
                             IntToDoubleFunction function)

Retrieves the value associated with the key if one exists; if it does not, associates the result of invoking the value function with the key.

Parameters:

key - the key

function - the function that provides the value if no mapping exists. The key will be passed as the argument to the function.

Returns:

the value associated with the key, if one exists, or the result of invoking function with key if not

getIfAbsentPutWith

<P> double getIfAbsentPutWith(int key,
                              DoubleFunction<? super P> function,
                              P parameter)

Retrieves the value associated with the key if one exists; if it does not, invokes the value function with the parameter and associates the result with the key.

Type Parameters:

P - the type of the value function's parameter

Parameters:

key - the key

function - the function that provides the value if no mapping exists. The specified parameter will be passed as the argument to the function.

parameter - the parameter to provide to function if no value exists for key

flipUniqueValues

MutableDoubleIntMap flipUniqueValues()

Return the DoubleIntMap that is obtained by flipping the direction of this map and making the associations from value to key.

Specified by:

flipUniqueValues in interface IntDoubleMap

Description copied from interface: IntDoubleMap

Return a copy of this map containing only the key/value pairs that match the predicate.
