Method: String#match?

Defined in:
string.c

#match?(pattern, offset = 0) ⇒ Boolean

Returns true or false based on whether a match is found for self and pattern.

Note: does not update Regexp@Global+Variables.

Computes regexp by converting pattern (if not already a Regexp).

regexp = Regexp.new(pattern)

Returns true if self+.match(regexp) returns a MatchData object, false otherwise:

'foo'.match?(/o/) # => true
'foo'.match?('o') # => true
'foo'.match?(/x/) # => false

If Integer argument offset is given, the search begins at index offset:

'foo'.match?('f', 1) # => false
'foo'.match?('o', 1) # => true

Returns:
