A regular expression criteria that matches attribute string values. For non
java.lang.String attributes, the
toString() form is used in the comparison.
Expressions are
always case insensitive The following special characters are supported:
- '?' - match any one single character
- '*' - match any multiple character(s) (including zero)
The supported wildcard characters can be escaped with a backslash '\', and a literal backslash can be included with '\\'
WARN: Expressions starting with a leading wildcard character are potentially very expensive (ie. full scan) for indexed caches
