Method Summary

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

Method Detail

put

float put(char key,
          float 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(char key,
                    float 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

float putOrAdd(char key,
               float putValue,
               float 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

float addTo(char key,
            float 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

float get(char 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(CharFloatAssociativeContainer 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 CharFloatCursor> 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

float remove(char 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

float getDefaultValue()

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

setDefaultValue

void setDefaultValue(float defaultValue)

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