class PatMatcher extends MatchResult with Matchable with Error
The PatMatcher class provides a simple means for using Java regular expressions.
Following the Facade design pattern, it combines functionality from both
Pattern and Matcher. A faster alternative is PatMatcherB, see below.

PatMatcher(regex: String)
- regex

def
=~(input: String): Boolean
The equal-match operator determines whether the 'input' string matches the given 'regex' string.

def
find(start: Int): Boolean
Resets this matcher and then attempts to find the next subsequence of the input sequence that matches the pattern, starting at the specified index.
Resets this matcher and then attempts to find the next subsequence of the input sequence that matches the pattern, starting at the specified index. Must call 'matcher' method first.
- start
the index to start searching for a match
-
def
find(): Boolean
Find the next occurrence of 'regex' in the 'input' string.
Find the next occurrence of 'regex' in the 'input' string. Must call 'matcher' method first.
