    - #### public static final int DOLLAR_SLASHY

    - #### public static final int NONE_SLASHY

    - #### public static final int SLASHY

  - ### Method Detail

    - #### public static long countChar(String text, char c)

    - #### public static boolean isEmpty(CharSequence cs)

      Copied from Apache commons-lang3-3.6

      Checks if a CharSequence is empty ("") or null.

           StringUtils.isEmpty(null)      = true
           StringUtils.isEmpty("")        = true
           StringUtils.isEmpty(" ")       = false
           StringUtils.isEmpty("bob")     = false
           StringUtils.isEmpty("  bob  ") = false

      NOTE: This method changed in Lang version 2.0. It no longer trims the CharSequence. That functionality is available in isBlank().

      Parameters:
        `cs` - the CharSequence to check, may be null
      Returns:
        `true` if the CharSequence is empty or null

    - #### public static boolean matches(String text, Pattern pattern)

    - #### public static String removeCR(String text)

    - #### public static String replace(String text, String searchString, String replacement)

      The modified implementation is based on StringUtils#replace(String text, String searchString, String replacement, int max), Apache commons-lang3-3.6

      Replaces all occurrences of a String within another String.

      A `null` reference passed to this method is a no-op.

           StringUtils.replace(null, *, *)        = null
           StringUtils.replace("", *, *)          = ""
           StringUtils.replace("any", null, *)    = "any"
           StringUtils.replace("any", *, null)    = "any"
           StringUtils.replace("any", "", *)      = "any"
           StringUtils.replace("aba", "a", null)  = "aba"
           StringUtils.replace("aba", "a", "")    = "b"
           StringUtils.replace("aba", "a", "z")   = "zbz"

      Parameters:
        `text` - text to search and replace in, may be null
        `searchString` - the String to search for, may be null
        `replacement` - the String to replace it with, may be null
      Returns:
        the text with any replacements processed, `null` if null String input
