int anchor

---

start

int[] start

---

end

int[] end

---

count

int[] count

Constructor Detail

REMatch

REMatch(int f_subs,
        int f_index)

Method Detail

finish

void finish(RECharIndexed text)

---

reset

void reset(int f_subIndex)

---

clear

void clear(int f_index)

---

toString

public java.lang.String toString()

Returns the string matching the pattern. This makes it convenient to write code like the following:

REMatch myMatch = myExpression.getMatch(myString);
if (myMatch != null) System.out.println("Regexp found: "+myMatch);

---

getStartIndex

public int getStartIndex()

Returns the index within the input text where the match in its entirety began.

---

getEndIndex

public int getEndIndex()

Returns the index within the input string where the match in its entirety ends. The return value is the next position after the end of the string; therefore, a match created by the following call:

REMatch myMatch = myExpression.getMatch(myString);

can be viewed (given that myMatch is not null) by creating

String theMatch = myString.substring(myMatch.getStartIndex(), myMatch.getEndIndex());

But you can save yourself that work, since the toString() method (above) does exactly that for you.

---

toString

public java.lang.String toString(int sub)

Returns the string matching the given subexpression.

---

getSubStartIndex

public int getSubStartIndex(int sub)

Returns the index within the input string used to generate this match where subexpression number sub begins, or -1 if the subexpression does not exist.

---

getSubEndIndex

public int getSubEndIndex(int sub)

Returns the index within the input string used to generate this match where subexpression number sub ends, or -1 if the subexpression does not exist.

---

substituteInto

public java.lang.String substituteInto(java.lang.String input)

Substitute the results of this match to create a new string. This is patterned after PERL, so the tokens to watch out for are $0 through $9. $0 matches the full substring matched; $n matches subexpression number n.
