Class SubstringVar

public class SubstringVar extends MultipartVar
A transformational variable resolver that returns substring for given start and end (optional)

The format for this var is one of the following:

  • "$ST{arg,start}"
  • "$ST{arg,start,end}"


// Create a variable resolver that resolves system properties and $SW vars. VarResolver varResolver = VarResolver.create().vars(SubstringVar.class, SystemPropertiesVar.class).build(); // Use it! System.out.println(varResolver.resolve("Version = $ST{$P{java.version}, 0, 3}"));

Since this is a MultipartVar, 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.
