# matchAsPrefix method

Match matchAsPrefix (String string, [ int start = 0 ])

Match this pattern against the start of `string`.

If `start` is provided, it must be an integer in the range `0` .. `string.length`. In that case, this patten is tested against the string at the `start` position. That is, a Match is returned if the pattern can match a part of the string starting from position `start`. Returns `null` if the pattern doesn't match.

## Implementation

    Match matchAsPrefix(String string, [int start = 0]);
