      • test

        @Deprecated
public boolean test​(double operand)
        Deprecated.
        Please use the corresponding type-specific method instead.

        In this default implementation, the key gets narrowed down to the actual key type, throwing an exception if the given key can't be represented in the restricted domain. This is done for interoperability with the Java 8 function environment. Its use is discouraged, as unexpected errors can occur. Instead, the corresponding classes should be used (e.g., Int2IntFunction instead of Short2IntFunction).

        Specified by:
        test in interface DoublePredicate
        Specified by:
        test in interface Float2BooleanFunction

      • size

        public int size()
        Description copied from interface: Function
        Returns the intended number of keys in this function, or -1 if no such number exists.

        Most function implementations will have some knowledge of the intended number of keys in their domain. In some cases, however, this might not be possible. This default implementation, in particular, returns -1.

        Specified by:
        size in interface Function<Float,​Boolean>
        Returns:
        the intended number of keys in this function, or -1 if that number is not available.

      • defaultReturnValue

        public boolean defaultReturnValue()
        Description copied from interface: Float2BooleanFunction
        Gets the default return value.

        This default implementation just return the default null value of the type (null for objects, 0 for scalars, false for Booleans).

        Specified by:
        defaultReturnValue in interface Float2BooleanFunction
        Returns:
        the current default return value.

      • defaultReturnValue

        public void defaultReturnValue​(boolean defRetValue)
        Description copied from interface: Float2BooleanFunction
        Sets the default return value (optional operation). This value must be returned by type-specific versions of get(), put() and remove() to denote that the map does not contain the specified key. It must be 0/false/null by default.
        Specified by:
        defaultReturnValue in interface Float2BooleanFunction
        Parameters:
        defRetValue - the new default return value.
        See Also:
        Float2BooleanFunction.defaultReturnValue()

      • containsKey

        public boolean containsKey​(float k)
        Description copied from interface: Float2BooleanFunction
        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 Float2BooleanFunction
        Parameters:
        k - the key.
        Returns:
        true if this function associates a value to key.
        See Also:
        Function.containsKey(Object)

      • clear

        public void clear()
        Description copied from interface: Function
        Removes all associations from this function (optional operation).
        Specified by:
        clear in interface Function<Float,​Boolean>
        See Also:
        Map.clear()

      • get

        @Deprecated
public Boolean get​(Object k)
        Deprecated.
        Please use the corresponding type-specific method instead.
        Returns the value associated by this function to the specified key.
        Specified by:
        get in interface Float2BooleanFunction
        Specified by:
        get in interface Function<Float,​Boolean>
        Parameters:
        k - the key.
        Returns:
        the corresponding value, or null if no value was present for the given key.
        See Also:
        Map.get(Object)

      • remove

        @Deprecated
public Boolean remove​(Object k)
        Deprecated.
        Please use the corresponding type-specific method instead.
        Removes this key and the associated value from this function if it is present (optional operation).
        Specified by:
        remove in interface Float2BooleanFunction
        Specified by:
        remove in interface Function<Float,​Boolean>
        Parameters:
        k - the key.
        Returns:
        the old value, or null if no value was present for the given key.

        Map.remove(Object)
