代码示例

代码示例来源：origin: apache/hbase

public JoniRegexEngine(String regex, int flags) {
 this.regex = regex;
 byte[] b = Bytes.toBytes(regex);
 this.pattern = new Regex(b, 0, b.length, patternToJoniFlags(flags), encoding, Syntax.Java);
}

代码示例来源：origin: apache/hbase

@Override
public int compareTo(byte[] value, int offset, int length) {
 // Use subsequence match instead of full sequence match to adhere to the
 // principle of least surprise.
 Matcher m = pattern.matcher(value);
 return m.search(offset, length, pattern.getOptions()) < 0 ? 1 : 0;
}

代码示例来源：origin: stackoverflow.com

Regex r = new Regex("YOURREGEX");

// search for a match within a string
r.search("YOUR STRING YOUR STRING");

if(r.didMatch()){
// Prints "true" -- r.didMatch() is a boolean function
// that tells us whether the last search was successful
// in finding a pattern.
// r.left() returns left String , string before the matched pattern 
int index = r.left().length();
}

代码示例来源：origin: stackoverflow.com

Regex r = new Regex(@"^(\1.|^.)+$");

Console.WriteLine(r.IsMatch("aababc"));     // True
Console.WriteLine(r.IsMatch("1121231234")); // True
Console.WriteLine(r.IsMatch("iLoveRegEx")); // False

for (int n = 0; n <= 50; n++) {
  Match m = r.Match("".PadLeft(n));
  if (m.Success) {
    Console.WriteLine("{0} = sum(1..{1})", n, m.Groups[1].Length);
  }
}
// 1 = sum(1..1)
// 3 = sum(1..2)
// 6 = sum(1..3)
// 10 = sum(1..4)
// 15 = sum(1..5)
// 21 = sum(1..6)
// 28 = sum(1..7)
// 36 = sum(1..8)
// 45 = sum(1..9)
