Method: Sequence::StringLike#match

Defined in:
lib/sequence/stringlike.rb

#match(rex, anchored = true, len = maxmatchlen(false)) ⇒ Object

like match_fast, but anchors work correctly and post_match is set to something, if not exactly what you expected. (an Sequence, not String.) 2nd parameter determines if match is anchored on the left side to the current position or not.
