substring static method
Creates a Filter that matches on a substring.
The pattern
must be a String of the form 'attr=match', where attr is
the attribute name and match is a value that has at least one *
character. There can be wildcard *
chararcters at the beginning, middle
or end of match.
The match must not be a single *
(e.g. 'foo=*' is not permitted). If
such a filter is required, use the present filter instead.
Implementation
static Filter substring(String attribute, String pattern) =>
SubstringFilter.fromPattern(attribute, pattern);
