Method Detail

containsKey

public boolean containsKey(int key)

Description copied from interface: Int2ObjectFunction

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 Int2ObjectFunction<V>

Parameters:

key - the key.

Returns:

true if this function associates a value to key.

See Also:

Function.containsKey(Object)

@Deprecated
public boolean containsKey(java.lang.Object key)

Deprecated.

Specified by:

containsKey in interface Int2ObjectFunction<V>

Parameters:

key - the key.

Returns:

true if this function associates a value to key.

get

public V get(int key)

Description copied from interface: Int2ObjectFunction

Returns the value to which the given key is mapped.

Specified by:

get in interface Int2ObjectFunction<V>

Parameters:

key - the key.

Returns:

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

get

@Deprecated
public V get(java.lang.Object key)

Deprecated.

Description copied from interface: Int2ObjectFunction

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

Specified by:

get in interface Int2ObjectFunction<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(java.lang.Integer key,
                         V value)

Deprecated.

Description copied from interface: Int2ObjectFunction

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

Specified by:

put in interface Int2ObjectFunction<V>

Parameters:

key - the key.

value - the value.

Returns:

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