    • replaceProperties

      public static String replaceProperties(String string)
      Go through the input string and replace any occurrence of ${p} with the System.getProperty(p) value. If there is no such property p defined, then the ${p} reference will remain unchanged. If the property reference is of the form ${p:v} and there is no such property p, then the default value v will be returned. If the property reference is of the form ${p1,p2} or ${p1,p2:v} then the primary and the secondary properties will be tried in turn, before returning either the unchanged input, or the default value. The property ${/} is replaced with System.getProperty("file.separator") value and the property ${:} is replaced with System.getProperty("path.separator").
      Parameters:
      string - - the string with possible ${} references
      Returns:
      the input string with all property references replaced if any. If there are no valid references the input string will be returned.

    • replaceProperties

      public static String replaceProperties(String string, Properties props)
      Go through the input string and replace any occurrence of ${p} with the props.getProperty(p) value. If there is no such property p defined, then the ${p} reference will remain unchanged. If the property reference is of the form ${p:v} and there is no such property p, then the default value v will be returned. If the property reference is of the form ${p1,p2} or ${p1,p2:v} then the primary and the secondary properties will be tried in turn, before returning either the unchanged input, or the default value. The property ${/} is replaced with System.getProperty("file.separator") value and the property ${:} is replaced with System.getProperty("path.separator").
      Parameters:
      string - - the string with possible ${} references
      props - - the source for ${x} property ref values, null means use System.getProperty()
      Returns:
      the input string with all property references replaced if any. If there are no valid references the input string will be returned.
