Method Detail

apply

public E apply(E input)

Description copied from interface: Function

Returns the result of applying this function to input. This method is generally expected, but not absolutely required, to have the following properties:

• Its execution does not cause any observable side effects.
• The computation is consistent with equals; that is, Objects.equal(a, b) implies that Objects.equal(function.apply(a), function.apply(b)).

Specified by:

apply in interface Function<E,E>

hashCode

public int hashCode()

Overrides:

hashCode in class java.lang.Object

equals

public boolean equals(java.lang.Object other)

Description copied from interface: Function

Indicates whether another object is equal to this function.

Most implementations will have no reason to override the behavior of Object.equals(java.lang.Object). However, an implementation may also choose to return true whenever object is a Function that it considers interchangeable with this one. "Interchangeable" typically means that Objects.equal(this.apply(f), that.apply(f)) is true for all f of type F. Note that a false result from this method does not imply that the functions are known not to be interchangeable.

Specified by:

equals in interface Function<E,E>

Overrides:

equals in class java.lang.Object
