org.codehaus.groovy.transform.tailrec.TernaryToIfStatementConverter

public class TernaryToIfStatementConverter
extends Object

Since a ternary statement has more than one exit point tail-recursiveness testing cannot be easily done. Therefore this class translates a ternary statement (or Elvis operator) into the equivalent if-else statement.
