Method Details
-
regex
Matches only cells from rows whose keys satisfy the given RE2 regex. In other words, passes through the entire row when the key matches, and otherwise produces an empty row. Note that, since row keys can contain arbitrary bytes, the `\C` escape sequence must be used if a true wildcard is desired. The `.` character will not match the new line character `\n`, which may be present in a binary key. -
