Fields Summary

Constructors Summary

Methods Summary
public int	end() Returns the offset after the last character matched. return @return The offset after the last character matched throws IllegalStateException If no match has yet been attempted, or if the previous match operation failed
public int	end(int 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(). param group The index of a capturing group in this matcher's pattern return 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 throws IllegalStateException If no match has yet been attempted, or if the previous match operation failed throws IndexOutOfBoundsException If there is no capturing group in the pattern with the given index
public java.lang.String	group() Returns the input subsequence matched by the previous match. For a matcher m with input sequence s, the expressions m.group() and s.substring(m.start(), m.end()) are equivalent. Note that some patterns, for example a*, match the empty string. This method will return the empty string when the pattern successfully matches the empty string in the input. return The (possibly empty) subsequence matched by the previous match, in string form throws IllegalStateException If no match has yet been attempted, or if the previous match operation failed
public java.lang.String	group(int 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. param group The index of a capturing group in this matcher's pattern return The (possibly empty) subsequence captured by the group during the previous match, or null if the group failed to match part of the input throws IllegalStateException If no match has yet been attempted, or if the previous match operation failed throws IndexOutOfBoundsException If there is no capturing group in the pattern with the given index
public int	groupCount() 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. return The number of capturing groups in this matcher's pattern
public int	start() Returns the start index of the match. return The index of the first character matched throws IllegalStateException If no match has yet been attempted, or if the previous match operation failed
public int	start(int 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(). param group The index of a capturing group in this matcher's pattern return 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 throws IllegalStateException If no match has yet been attempted, or if the previous match operation failed throws IndexOutOfBoundsException If there is no capturing group in the pattern with the given index
