java.lang.Object

org.utplsql.api.EnvironmentVariableUtil

public class EnvironmentVariableUtil
extends Object

This class provides an easy way to get environmental variables. This is mainly to improve testability but also to standardize the way how utPLSQL API and CLI read from environment.

Variables are obtained from the following scopes in that order (chain breaks as soon as a value is obtained):

• Properties (System.getProperty())
• Environment (System.getEnv())
• Default value

An empty string is treated the same as null.
