gnu.regexp .REMatch

REMatch
public class REMatch (Code)
	An instance of this class represents a match completed by a gnu.regexp matching function. It can be used to obtain relevant information about the location of a match or submatch. author: Wes Biggs

Field Summary
int[]	count
int[]	end
int	offsetanchor
int[]	start

Constructor Summary
	REMatch(int f_subs, int f_index)

Method Summary
void	clear(int f_index)
void	finish(CharIndexed text)
public int	getEndIndex() Returns the index within the input string where the match in its entirety ends.
public int	getStartIndex() Returns the index within the input text where the match in its entirety began.
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.
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.
void	reset(int f_subIndex)
public String	substituteInto(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`.
public String	toString() Returns the string matching the pattern.
public String	toString(int sub) Returns the string matching the given subexpression.

Field Detail

count
int[] count(Code)

end
int[] end(Code)

offsetanchor
int offsetanchor(Code)

start
int[] start(Code)

Constructor Detail

REMatch
REMatch(int f_subs, int f_index)(Code)

Method Detail

clear
void clear(int f_index)(Code)

finish
void finish(CharIndexed text)(Code)

getEndIndex

public int getEndIndex()(Code)

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.

getStartIndex
public int getStartIndex()(Code)
	Returns the index within the input text where the match in its entirety began.

getSubEndIndex
public int getSubEndIndex(int sub)(Code)
	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. Parameters: sub - Subexpression index

getSubStartIndex
public int getSubStartIndex(int sub)(Code)
	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. Parameters: sub - Subexpression index

reset
void reset(int f_subIndex)(Code)

substituteInto
public String substituteInto(String input)(Code)
	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. Parameters: input - A string consisting of literals and `$n` tokens.

toString
public String toString()(Code)
	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);`

toString
public String toString(int sub)(Code)
	Returns the string matching the given subexpression. Parameters: sub - Index of the subexpression.
