Method Summary

Modifier and Type	Method and Description
double	addTo(long key, double additionValue) An equivalent of calling putOrAdd(key, additionValue, additionValue);
void	clear() Clear all keys and values in the container.
double	get(long key)
double	getDefaultValue() Returns the "default value" value used in containers methods returning "default value"
double	put(long key, double value) Place a given key and value in the container.
int	putAll(java.lang.Iterable<? extends LongDoubleCursor> iterable) Puts all keys from an iterable cursor to this map, replacing the values of existing keys, if such keys are present.
int	putAll(LongDoubleAssociativeContainer container) Puts all keys from another container to this map, replacing the values of existing keys, if such keys are present.
boolean	putIfAbsent(long key, double value) Trove-inspired API method.
double	putOrAdd(long key, double putValue, double additionValue) If key exists, putValue is inserted into the map, otherwise any existing value is incremented by additionValue.
double	remove(long key) Remove the (key, value) pair associated with the given key, and returns the assocaited value.
void	setDefaultValue(double defaultValue) Set the "default value" value to be used in containers methods returning "default value"

Method Detail

put

double put(long key,
           double value)

Place a given key and value in the container.

Returns:

Returns the value previously stored under the given key, if an equal key is already in the map and replaces the existing value only with the argument value. If the given key was not already in the map, the given (key, value) pair is inserted in the map and the default value is returned.

putIfAbsent

boolean putIfAbsent(long key,
                    double value)

Trove-inspired API method. An equivalent of the following code:

 if (!map.containsKey(key))
      map.put(key, value);
 

Parameters:

key - The key of the value to check.

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

Returns:

true if key did not exist and value was placed in the map.

putOrAdd

double putOrAdd(long key,
                double putValue,
                double additionValue)

If key exists, putValue is inserted into the map, otherwise any existing value is incremented by additionValue.

Parameters:

key - The key of the value to adjust.

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

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

Returns:

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

addTo

double addTo(long key,
             double 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).

get

double get(long key)

Returns:

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

putAll

int putAll(LongDoubleAssociativeContainer 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 LongDoubleCursor> 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

double remove(long key)

Remove the (key, value) pair associated with the given key, and returns the assocaited value. The default value is returned if the key did not exist in the map.

Parameters:

key -

clear

void clear()

Clear all keys and values in the container.

getDefaultValue

double getDefaultValue()

Returns the "default value" value used in containers methods returning "default value"

setDefaultValue

void setDefaultValue(double defaultValue)

Set the "default value" value to be used in containers methods returning "default value"
