[Groovy] Class UnnecessaryCallForLastElementRule

java.lang.Object
  org.codenarc.rule.AbstractRule
      org.codenarc.rule.AbstractAstVisitorRule
          org.codenarc.rule.unnecessary.UnnecessaryCallForLastElementRule

class UnnecessaryCallForLastElementRule
extends AbstractAstVisitorRule

This rule checks for excessively verbose methods of accessing the last element of an array or list. For instance, it is possible to access the last element of an array by performing array[array.length - 1], in Groovy it is simpler to either call array.last() or array[-1]. The same is true for lists. This violation is triggered whenever a get, getAt, or array-style access is used with an object size check.
