    - #### getUpperCaseSeparationPrefix

          public String getUpperCaseSeparationPrefix()

      Returns the prefix which is used as Separator when an upper case character is encountered after a lower case character.
      Returns:
        the separator which is inserted between a lower case character and an upper case character.

    - #### setUpperCaseSeparationPrefix

          public void setUpperCaseSeparationPrefix(String upperCaseSeparationPrefix)

      Sets the prefix which is used as Separator when an upper case character is encountered after a lower case character.
      Parameters:
        `upperCaseSeparationPrefix` - the separator which is inserted between a lower case character and an upper case character.

    - #### process

          public String process(String toProcess)

      Replaces all characters in `toProcess` which occur in `toReplace` with `toReplaceWith`; groups of special characters are treated as one. Inserts `UPPER_CASE_SEPPARATION_PREFIX` if an upper case character follows a lower case character, and converts all charcters to upper case. If the string starts is empty or start with a number, the character `toReplaceWith` is prefixed to the constant name. Finally, the new String is returned.

      Example: "prOceSS-*+ing~#._Test" is converted to "PR_OCE_SS_ING_TEST"

      Specified by:
        `process` in interface `StringProcessor`
      Overrides:
        `process` in class `CharReplacer`
      Parameters:
        `toProcess` - the String in which replacement should occur, not null.
      Returns:
        the processed String, not null.
