Method Details

containsKey

public boolean containsKey(int key)

Description copied from interface: Int2BooleanFunction

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 Int2BooleanFunction

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: Int2BooleanFunction

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<Integer,Boolean>

Specified by:

containsKey in interface Int2BooleanFunction

Parameters:

key - the key.

Returns:

true if this function associates a value to key.

• Map.containsKey(Object)

get

public boolean get(int key)

Description copied from interface: Int2BooleanFunction

Returns the value to which the given key is mapped.

Specified by:

get in interface Int2BooleanFunction

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 boolean getOrDefault(int key,
 boolean defaultValue)

Description copied from interface: Int2BooleanFunction

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

Specified by:

getOrDefault in interface Int2BooleanFunction

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:

getOrDefault in interface Function<Integer,Boolean>

Specified by:

getOrDefault in interface Int2BooleanFunction

Parameters:

key - the key.

defaultValue - the default value to return if not present.

put

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

Deprecated.

Description copied from interface: Int2BooleanFunction

Specified by:

put in interface Function<Integer,Boolean>

Specified by:

put in interface Int2BooleanFunction

Parameters:

key - the key.

value - the value.

Returns:

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