Method Detail

containsKey

public boolean containsKey(double key)

Description copied from interface: Double2ReferenceFunction

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 Double2ReferenceFunction<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.

Specified by:

containsKey in interface Double2ReferenceFunction<V>

Parameters:

key - the key.

Returns:

true if this function associates a value to key.

Map.containsKey(Object)

get

public V get(double key)

Description copied from interface: Double2ReferenceFunction

Returns the value to which the given key is mapped.

Specified by:

get in interface Double2ReferenceFunction<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:

Function.get(Object)

get

@Deprecated
public V get(Object key)

Deprecated.

Description copied from interface: Double2ReferenceFunction

Returns the value associated by this function to the specified key.

Specified by:

get in interface Double2ReferenceFunction<V>

Parameters:

key - the key.

Returns:

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

See Also:

Map.get(Object)

put

@Deprecated
public V put(Double key,
                         V value)

Deprecated.

Description copied from interface: Double2ReferenceFunction

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

Specified by:

put in interface Double2ReferenceFunction<V>

Parameters:

key - the key.

value - the value.

Returns:

the old value, or null if no value was present for the given key.
