Constant (cactoos 0.55.0 API)

java.lang.Object
- org.cactoos.scalar.Constant<T>

Type Parameters:

T - Type of result

All Implemented Interfaces:

Scalar<T>
```
public final class Constant<T>
extends Object
implements Scalar<T>
```
Constant value.
This Scalar represents a constant value which never changes.

Contrary to Sticky this constant is always pre-computed.

This class implements Scalar, which throws a checked Exception. Despite that this class does NOT throw a checked exception as it only returns a pre-computed value.

Example:
```
     final Scalar<String> constant = new Constant<>("Value");
     System.out.print("Constant is always the same: ");
     System.out.println(constant.value() == constant.value());
 
```
This class is thread-safe.

0.30
