class TPMERegexp: protected TPRegexp

 Default constructor. This regexp will match an empty string.

 Constructor:
  s    - string to compile into regular expression
  opts - perl-style character flags to be set on TPME object

 Constructor:
  s    - string to copmile into regular expression
  opts - PCRE-style option flags to be set on TPME object

 Copy constructor.
 Only PCRE specifics are copied, not last-match or global-matech
 information.

 Reset the patteren and options.
 If 'nMatchMax' other than -1 (the default) is passed, it is also set.

 Reset the patteren and options.
 If 'nMatchMax' other than -1 (the default) is passed, it is also set.

 Copy global-match state from 're; so that this regexp can continue
 parsing the string from where 're' left off.

 Alternatively, GetGlobalPosition() get be used to retrieve the
 last match position so that it can passed to Match().

 Ideally, as it is done in PERL, the last match position would be
 stored in the TString itself.

 Reset state of global match.
 This happens automatically when a new string is passed for matching.
 But be carefull, as the address of last TString object is used
 to make this decision.

 Runs a match on s against the regex 'this' was created with.

 Args:
  s        - string to match against
  start    - offset at which to start matching
 Returns:  - number of matches found

 Splits into at most maxfields. If maxfields is unspecified or
 0, trailing empty matches are discarded. If maxfields is
 positive, no more than maxfields fields will be returned and
 trailing empty matches are preserved. If maxfields is empty,
 all fields (including trailing empty ones) are returned. This
 *should* be the same as the perl behaviour.

 If pattern produces sub-matches, these are also stored in
 the result.

 A pattern matching the null string will split the value of EXPR
 into separate characters at each point it matches that way.

 Args:
  s         - string to split
  maxfields - maximum number of fields to be split out.  0 means
              split all fields, but discard any trailing empty bits.
              Negative means split all fields and keep trailing empty bits.
              Positive means keep up to N fields including any empty fields
              less than N. Anything remaining is in the last field.
 Returns:   - number of fields found

 Substitute matching part of s with r, dollar back-ref
 substitution is performed if doDollarSubst is true (default).
 Returns the number of substitutions made.

 After the substitution, another pass is made over the resulting
 string and the following special tokens are interpreted:
 \l - lowercase next char,
 \u - uppercase next char,
 \L - lowercase till \E,
 \U - uppercase till \E, and
 \E - end case modification.

 Returns the sub-string from the internal fMarkers vector.
 Requires having run match or split first.

 Print the regular expression and modifier options.
 If 'option' contains "all", prints also last string match and
 match results.
