Method Detail

test

public boolean test(Generator<? extends T> left,
                    UnaryPredicate<? super T> right)
Evaluate this predicate.

Specified by:
test in interface BinaryPredicate<Generator<? extends T>,UnaryPredicate<? super T>>
Parameters:
left - Generator
right - UnaryPredicate
Returns:
the result of this test for the given arguments

equals

public boolean equals(Object obj)
Indicates whether some other object is "equal to" this functor. This method must adhere to general Object.equals contract. Additionally, this method can return true only if the specified Object implements the same functor interface and is known to produce the same results and/or side-effects for the same arguments (if any).

While implementators are strongly encouraged to override the default Object implementation of this method, note that the default Object implementation does in fact adhere to the functor equals contract.

Specified by:
equals in interface Functor
Overrides:
equals in class Object
Parameters:
obj - the object to compare this functor to
Returns:
true iff the given object implements this functor interface, and is known to produce the same results and/or side-effects for the same arguments (if any).

Functor.hashCode()

hashCode

public int hashCode()
Returns a hash code for this functor adhering to the general Object.hashCode contract. Implementators are strongly encouraged but not strictly required to override the default Object implementation of this method.

Specified by:
hashCode in interface Functor
Overrides:
hashCode in class Object
Returns:
a hash code for this functor
See Also:
Functor.equals(java.lang.Object)

instance

public static GeneratorContains<Object> instance()
Get a static GeneratorContains instance.

Returns:
GeneratorContains
