Package org.eolang

Class PhSafe

java.lang.Object

org.eolang.PhSafe

All Implemented Interfaces:

Atom, Data, Phi

public final class PhSafe
extends Object
implements Phi, Atom

An object with coordinates (line and position) and a safe processing of any runtime errors.

It is used to wrap any object and provide a safe processing of any runtime errors. It is used in the EO runtime to provide a safe processing of any runtime errors in the EO code. If, in any method invocation, a runtime error occurs, it is caught and wrapped into EOerror.ExError with the location of the error in the EO code.
