Field Details

inner

private final Function<A,B> inner

The field for the inner record component.

invocationCount

private final AtomicInteger invocationCount

The field for the invocationCount record component.

Constructor Details

InvocationCounter

public InvocationCounter(Function<A,B> inner,
 AtomicInteger invocationCount)

Creates an instance of a InvocationCounter record class.

Parameters:

inner - the value for the inner record component

invocationCount - the value for the invocationCount record component

Method Details

of

public static <A,
B> InvocationCounter<A,B> of(Function<A,B> inner)

Count the number of invocations of inner by wrapping it.

justCount

public static <A> InvocationCounter<A,A> justCount()

Count the number of invocations of the identity function.

apply

public B apply(A a)

Specified by:

apply in interface Function<A,B>

toString

public final String toString()

Returns a string representation of this record class. The representation contains the name of the class, followed by the name and value of each of the record components.

Specified by:

toString in class Record

Returns:

a string representation of this object

hashCode

public final int hashCode()

Returns a hash code value for this object. The value is derived from the hash code of each of the record components.

Specified by:

hashCode in class Record

Returns:

a hash code value for this object

equals

public final boolean equals(Object o)

Indicates whether some other object is "equal to" this one. The objects are equal if the other object is of the same class and if all the record components are equal. All components in this record class are compared with Objects::equals(Object,Object).

Specified by:

equals in class Record

Parameters:

o - the object with which to compare

Returns:

true if this object is the same as the o argument; false otherwise.

inner

public Function<A,B> inner()

Returns the value of the inner record component.

Returns:

the value of the inner record component

invocationCount

public AtomicInteger invocationCount()

Returns the value of the invocationCount record component.

Returns:

the value of the invocationCount record component
