Method Detail

apply

T apply(F from)

Applies the function to an object of type F, resulting in an object of type T. Note that types F and T may or may not be the same.

Parameters:

from - the source object

Returns:

the resulting object

equals

boolean equals(Object obj)

Indicates whether some other object is equal to this Function. This method can return true only if the specified object is also a Function and, for every input object o, it returns exactly the same value. Thus, function1.equals(function2) implies that either function1.apply(o) and function2.apply(o) are both null, or function1.apply(o).equals(function2.apply(o)).

Note that it is always safe not to override Object.equals(java.lang.Object).

Overrides:

equals in class Object
