Reference documentation and code samples for the Cloud Bigtable Client class QualifierFilter.
A builder used to configure qualifier based filters.
Example:
use Google\Cloud\Bigtable\Filter;
$builder = Filter::qualifier();
Methods
regex
Matches only cells from columns whose qualifiers satisfy the given
RE2 regex. Note that, since
column qualifiers 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
qualifier.
Example:
$qualifierFilter = $builder->regex('prefix.*');
