jdk.util.regex.MatchResult
The result of a match operation.
This interface contains query methods used to determine the results of a match against a regular expression. The match boundaries, groups and group boundaries can be seen but not modified through a MatchResult.

endclj
(end this)(end this group)Returns the offset after the last character of the subsequence captured by the given group during this match.
Capturing groups are indexed from left to right, starting at one. Group zero denotes the entire pattern, so the expression m.end(0) is equivalent to m.end().
group - The index of a capturing group in this matcher's pattern - int
returns: The offset after the last character captured by the group,
or -1 if the match was successful
but the group itself did not match anything - int
throws: java.lang.IllegalStateException - If no match has yet been attempted, or if the previous match operation failed
Returns the offset after the last character of the subsequence
captured by the given group during this match.
Capturing groups are indexed from left
to right, starting at one. Group zero denotes the entire pattern, so
the expression m.end(0) is equivalent to
m.end().
group - The index of a capturing group in this matcher's pattern - `int`
returns: The offset after the last character captured by the group,
or -1 if the match was successful
but the group itself did not match anything - `int`
throws: java.lang.IllegalStateException - If no match has yet been attempted, or if the previous match operation failedgroupclj
(group this)(group this group)Returns the input subsequence captured by the given group during the previous match operation.
For a matcher m, input sequence s, and group index g, the expressions m.group(g) and s.substring(m.start(g), m.end(g)) are equivalent.
Capturing groups are indexed from left to right, starting at one. Group zero denotes the entire pattern, so the expression m.group(0) is equivalent to m.group().
If the match was successful but the group specified failed to match any part of the input sequence, then null is returned. Note that some groups, for example (a*), match the empty string. This method will return the empty string when such a group successfully matches the empty string in the input.
group - The index of a capturing group in this matcher's pattern - int
returns: The (possibly empty) subsequence captured by the group
during the previous match, or null if the group
failed to match part of the input - java.lang.String
throws: java.lang.IllegalStateException - If no match has yet been attempted, or if the previous match operation failed
Returns the input subsequence captured by the given group during the
previous match operation.
For a matcher m, input sequence s, and group index
g, the expressions m.group(g) and
s.substring(m.start(g), m.end(g))
are equivalent.
Capturing groups are indexed from left
to right, starting at one. Group zero denotes the entire pattern, so
the expression m.group(0) is equivalent to m.group().
If the match was successful but the group specified failed to match
any part of the input sequence, then null is returned. Note
that some groups, for example (a*), match the empty string.
This method will return the empty string when such a group successfully
matches the empty string in the input.
group - The index of a capturing group in this matcher's pattern - `int`
returns: The (possibly empty) subsequence captured by the group
during the previous match, or null if the group
failed to match part of the input - `java.lang.String`
throws: java.lang.IllegalStateException - If no match has yet been attempted, or if the previous match operation failedgroup-countclj
(group-count this)Returns the number of capturing groups in this match result's pattern.
Group zero denotes the entire pattern by convention. It is not included in this count.
Any non-negative integer smaller than or equal to the value returned by this method is guaranteed to be a valid group index for this matcher.
returns: The number of capturing groups in this matcher's pattern - int

startclj
(start this)(start this group)Returns the start index of the subsequence captured by the given group during this match.
Capturing groups are indexed from left to right, starting at one. Group zero denotes the entire pattern, so the expression m.start(0) is equivalent to m.start().
group - The index of a capturing group in this matcher's pattern - int
returns: The index of the first character captured by the group,
or -1 if the match was successful but the group
itself did not match anything - int
throws: java.lang.IllegalStateException - If no match has yet been attempted, or if the previous match operation failed
Returns the start index of the subsequence captured by the given group
during this match.
Capturing groups are indexed from left
to right, starting at one. Group zero denotes the entire pattern, so
the expression m.start(0) is equivalent to
m.start().
group - The index of a capturing group in this matcher's pattern - `int`
