 @CheckReturnValue
public final class ImmutableNone<T>
extends Maybe.None<T>

Immutable implementation of Maybe.None.

Use the builder to create immutable instances: ImmutableNone.builder(). Use the static factory method to get the default singleton instance: ImmutableNone.of().

Method Detail

equals

public boolean equals(@Nullable
                      Object another)

This instance is equal to all instances of ImmutableNone that have equal attribute values.

Overrides:

equals in class Object

Returns:

true if this is equal to another instance

hashCode

public int hashCode()

Returns a constant hash code value.

Overrides:

hashCode in class Object

Returns:

hashCode value

toString

public String toString()

Prints the immutable value None.

Overrides:

toString in class Object

Returns:

A string representation of the value

of

public static <T> ImmutableNone<T> of()

Returns the default immutable singleton value of None

Returns:

An immutable instance of None

copyOf

public static <T> ImmutableNone<T> copyOf(Maybe.None<T> instance)

Creates an immutable copy of a Maybe.None value. Uses accessors to get values to initialize the new immutable instance. If an instance is already immutable, it is returned as is.

Type Parameters:

T - generic parameter T

Parameters:

instance - The instance to copy

Returns:

A copied immutable None instance

builder

public static <T> ImmutableNone.Builder<T> builder()

Creates a builder for ImmutableNone.

 ImmutableNone.<T>builder()
    .build();
 

Type Parameters:

T - generic parameter T

Returns:

A new ImmutableNone builder
