Method Summary  
int 
begin(int group)
Enabled: @param group The pattern subgroup. 
int 
beginOffset(int group)
Enabled: Returns an offset marking the beginning of the pattern match relative to the beginning of the input from which the match was extracted. 
int 
end(int group)
Enabled: @param group The pattern subgroup. 
int 
endOffset(int group)
Enabled: Returns an offset marking the end of the pattern match relative to the beginning of the input from which the match was extracted. 
String 
group(int group)
Enabled: Returns the contents of the parenthesized subgroups of a match, counting parentheses from left to right and starting from 1. 
int 
groups()
Enabled: @return The number of groups contained in the result. 
int 
length()
Enabled: A convenience method returning the length of the entire match. 
String 
toString()
Suppressed: Returns the same as group(0). 
Method Detail 
public int length()
group(int)
method to get
the string and then access its length() method as follows:
int length = 1; // Use 1 to indicate group doesn't exist MatchResult result; String subgroup; // Initialization of result omitted subgroup = result.group(1); if(subgroup != null) length = subgroup.length();
The length() method serves as a more a more efficient way to do:
length = result.group(0).length();
public int groups()
public String group(int group)
foo(\d+)
is used to extract a match
from the input abfoo123
, then group(0)
will return foo123
and group(1)
will return
123
. group(2)
will return
null
because there is only one subgroup in the original
pattern.
group
 The pattern subgroup to return.
public int begin(int group)
public int end(int group)
public int beginOffset(int group)
group
 The pattern subgroup.
public int endOffset(int group)
group
 The pattern subgroup.
public String toString()
toString
in class Object
