Class LineListSubset

java.lang.Object
  tools.web.LineListSubset

public class LineListSubset
extends java.lang.Object

This static utility class finds a subset of lines within a list of lines. Start and stop indicators are used to define the subset.

For instance: "contains(blah)*2-4" finds the second line (*2) that contains the text "blah". The target line is four above this (-4).

If a start indicator is not given, the first line begins the subset. If the stop indicator is not given, the last line ends the subset.
