Package org.eolang

Class Data.ToPhi

java.lang.Object

org.eolang.Data.ToPhi

All Implemented Interfaces:

Phi, Term

Enclosing interface:

Data<T>

public static final class Data.ToPhi
extends Object
implements Phi

Makes a Phi out of a Java object, like String or Integer.

This is more convenient than making EOstring and then injecting "Δ" into it. This class is used in Java tests mostly for the sake of brevity. In auto-generated Java code we use EOint/EOstring and then inject "Δ" with Data.Value into it.

0.1
