public class LocalVariableNameCheck extends AbstractNameCheck
Checks that local, non-final variable names conform to a format specified
by the format property. A catch parameter is considered to be
a local variable. The format is a
regular expression
and defaults to
^[a-z][a-zA-Z0-9]*$.
An example of how to configure the check is:
<module name="LocalVariableName"/>
An example of how to configure the check for names that begin with a lower case letter, followed by letters, digits, and underscores is:
<module name="LocalVariableName">
<property name="format" value="^[a-z](_?[a-zA-Z0-9]+)*$"/>
</module>
An example of one character variable name in initialization expression(like "i") in FOR loop:
for(int i = 1; i < 10; i++) {}
An example of how to configure the check to allow one char variable name in initialization expressions in FOR loop:
<module name="LocalVariableName">
<property name="allowOneCharVarInForLoop" value="true"/>
</module>
