Method Detail

containsKey

public boolean containsKey(int key)

Description copied from interface: Int2ByteFunction

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 Int2ByteFunction

Parameters:

key - the key.

Returns:

true if this function associates a value to key.

See Also:

Function.containsKey(Object)

@Deprecated
public boolean containsKey(Object key)

Deprecated.

Specified by:

containsKey in interface Int2ByteFunction

Parameters:

key - the key.

Returns:

true if this function associates a value to key.

Description copied from interface: Int2ByteFunction

Returns the value to which the given key is mapped.

Specified by:

get in interface Int2ByteFunction

Parameters:

key - the key.

Returns:

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

put

@Deprecated
public Byte put(Integer key,
                            Byte value)

Deprecated.

Description copied from interface: Int2ByteFunction

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

Specified by:

put in interface Int2ByteFunction

Parameters:

key - the key.

value - the value.
