Method Details

containsKey

public boolean containsKey(Object key)

Description copied from interface: Function

Returns true if this function contains a mapping for the specified key.

Note that for some kind of functions (e.g., hashes) this method will always return true. This default implementation, in particular, always return true.

Specified by:

containsKey in interface Function<K,Float>

Parameters:

key - the key.

Returns:

true if this function associates a value to key.

• Map.containsKey(Object)

getFloat

public float getFloat(Object key)

Description copied from interface: Reference2FloatFunction

Returns the value to which the given key is mapped.

Specified by:

getFloat in interface Reference2FloatFunction<K>

Parameters:

key - the key.

Returns:

the corresponding value, or the default return value if no value was present for the given key.

See Also:

• Function.get(Object)

getOrDefault

public float getOrDefault(Object key,
 float defaultValue)

Description copied from interface: Reference2FloatFunction

Returns the value associated by this function to the specified key, or give the specified value if not present.

Specified by:

getOrDefault in interface Reference2FloatFunction<K>

Parameters:

key - the key.

defaultValue - the value to return if not present.

Returns:

the corresponding value, or defaultValue if no value was present for the given key.

Specified by:

get in interface Function<K,Float>

Specified by:

get in interface Reference2FloatFunction<K>

Parameters:

key - the key.

getOrDefault in interface Function<K,Float>

Specified by:

getOrDefault in interface Reference2FloatFunction<K>

Parameters:

key - the key.

defaultValue - the default value to return if not present.

Returns:

the corresponding value, or defaultValue if no value was present for the given key.

• Map.getOrDefault(Object, Object)

put

@Deprecated
public Float put(K key,
 Float value)

Deprecated.

Description copied from interface: Reference2FloatFunction

Associates the specified value with the specified key in this function (optional operation).

Specified by:

put in interface Function<K,Float>

Specified by:

put in interface Reference2FloatFunction<K>

Parameters:

key - the key.

value - the value.
