Examples of java.util.regex.Matcher.lookingAt()

java.util.regex.Matcher.lookingAt()
Attempts to match the input sequence, starting at the beginning of the region, against the pattern.
Like the {@link #matches matches} method, this method always startsat the beginning of the region; unlike that method, it does not require that the entire region be matched.
If the match succeeds then more information can be obtained via the start, end, and group methods.
@return true if, and only if, a prefix of the inputsequence matches this matcher's pattern
