Method Detail

containsKey

public boolean containsKey(Object key)

Description copied from interface: Function

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.

Parameters:

key - the key.

Returns:

true if this function associates a value to key.

getBoolean

public boolean getBoolean(Object key)

Description copied from interface: Reference2BooleanFunction

Returns the value to which the given key is mapped.

Specified by:

getBoolean in interface Reference2BooleanFunction<K>

Parameters:

key - the key.

Returns:

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

@Deprecated
public Boolean get(Object key)

Deprecated.

Description copied from interface: Reference2BooleanFunction

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

Specified by:

Parameters:

key - the key.

Returns:

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