Reference documentation and code samples for the Cloud Bigtable Client class FamilyFilter.
A builder used to configure column family filters.
Example:
use Google\Cloud\Bigtable\Filter;
$builder = Filter::family();
Methods
regex
Matches only cells from columns whose families satisfy the given RE2 regex.
For technical reasons, the regex must not contain the : character, even
if it is not being used as literal. Note that, since column families
cannot contain the new line character \n, it is sufficient to use .
as a full wildcard when matching column family names.
Example:
$familyFilter = $builder->regex('prefix.*');
