Class ImmutableTriple<L,M,R>

java.lang.Object

org.aoju.bus.core.lang.tuple.Triple<L,M,R>

org.aoju.bus.core.lang.tuple.ImmutableTriple<L,M,R>

Type Parameters:

L - the left element type

M - the middle element type

R - the right element type

All Implemented Interfaces:

Serializable, Comparable<Triple<L,M,R>>

public final class ImmutableTriple<L,M,R>
extends Triple<L,M,R>

An immutable triple consisting of three Object elements.

Although the implementation is immutable, there is no restriction on the objects that may be stored. If mutable objects are stored in the triple, then the triple itself effectively becomes mutable. The class is also final, so a subclass can not add undesirable behaviour.

#ThreadSafe# if all three objects are thread-safe

Since:

Java 17+

Constructor Details

ImmutableTriple

public ImmutableTriple(L left,
 M middle,
 R right)

Create a new triple instance.

Parameters:

left - the left value, may be null

middle - the middle value, may be null

right - the right value, may be null

Method Details

nullTriple

public static <L,
M,
R> ImmutableTriple<L,M,R> nullTriple()

Returns an immutable triple of nulls.

Type Parameters:

L - the left element of this triple. Value is null.

M - the middle element of this triple. Value is null.

R - the right element of this triple. Value is null.

Returns:

an immutable triple of nulls.

of

public static <L,
M,
R> ImmutableTriple<L,M,R> of(L left,
 M middle,
 R right)

Obtains an immutable triple of three objects inferring the generic types.

This factory allows the triple to be created using inference to obtain the generic types.

Type Parameters:

L - the left element type

M - the middle element type

R - the right element type

Parameters:

left - the left element, may be null

middle - the middle element, may be null

right - the right element, may be null

Returns:

a triple formed from the three parameters, not null
