Cloud Bigtable Client - Class FamilyFilter (1.20.3)

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(); 

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.*'); 

Matches only cells from columns whose families match the value.

Example:

 $familyFilter = $builder->exactMatch('cf1');
