Class EnvVariablesVar

public class EnvVariablesVar extends DefaultingVar
Environment variable variable resolver.

The format for this var is "$E{envVar[,defaultValue]}".


// Create a variable resolver that resolves environment variables (e.g. "$E{PATH}") VarResolver varResolver = VarResolver.create().vars(EnvVariablesVar.class).build(); // Use it! System.out.println(varResolver.resolve("Environment variable PATH is set to $E{PATH}"));

Since this is a SimpleVar, any variables contained in the result will be recursively resolved.
Likewise, if the arguments contain any variables, those will be resolved before they are passed to this var.
