public class RecordTypeParameterNameCheck extends AbstractNameCheck
Checks that record type parameter names conform to a specified pattern.
-
Property
format
- Specifies valid identifiers. Type isjava.util.regex.Pattern
. Default value is"^[A-Z]$"
.
To configure the check:
<module name="RecordTypeParameterName"/>
An example of how to configure the check for names that are only a single letter is:
Configuration:
<module name="RecordTypeParameterName"> <property name="format" value="^[a-zA-Z]$"/> </module>
Example:
record MyRecord1<T> {} // OK record MyRecord2<t> {} // OK record MyRecord3<abc> {} // violation, the record type parameter // name should match the regular expression "^[a-zA-Z]$"
