Method Details

containsKey

public boolean containsKey(float key)

Description copied from interface: Float2ReferenceFunction

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. In particular, this default implementation always returns true.

Specified by:

containsKey in interface Float2ReferenceFunction<V>

Parameters:

key - the key.

Returns:

true if this function associates a value to key.

See Also:

• Function.containsKey(Object)

containsKey

@Deprecated
public boolean containsKey(Object key)

Deprecated.

Description copied from interface: Float2ReferenceFunction

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 Float2ReferenceFunction<V>

Specified by:

containsKey in interface Function<Float,V>

Parameters:

key - the key.

Returns:

true if this function associates a value to key.

• Map.containsKey(Object)

get

public V get(float key)

Description copied from interface: Float2ReferenceFunction

Returns the value to which the given key is mapped.

Specified by:

get in interface Float2ReferenceFunction<V>

Parameters:

key - the key.

Returns:

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

See Also:

getOrDefault

public V getOrDefault(float key,
 V defaultValue)

Description copied from interface: Float2ReferenceFunction

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

Specified by:

getOrDefault in interface Float2ReferenceFunction<V>

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.
