Method Detail

regex

public Filters.Filter regex(String 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.

exactMatch

public Filters.Filter exactMatch(com.google.protobuf.ByteString value)

Matches only cells from rows whose keys equal the value. In other words, passes through the entire row when the key matches, and otherwise produces an empty row.

sample

public Filters.Filter sample(double probability)

Matches all cells from a row with `probability`, and matches no cells from the row with probability 1-`probability`.
