Class Check.NumericRegularExpressionHolder

java.lang.Object
  net.sf.qualitycheck.Check.NumericRegularExpressionHolder

Enclosing class:

Check

protected static final class Check.NumericRegularExpressionHolder
extends Object

Holder for the regular expression to determine numeric values. Using the holder pattern guarantees that the regular expression is initialized before the first use (thread safe!) and that it is only initialized if it is needed. So, we do not pay any performance bounty for regular expressions when using other checks.
