Class InefficientStringBufferingRule

java.lang.Object

net.sourceforge.pmd.properties.AbstractPropertySource

net.sourceforge.pmd.lang.rule.AbstractRule

net.sourceforge.pmd.lang.java.rule.AbstractJavaRule

net.sourceforge.pmd.lang.java.rule.performance.InefficientStringBufferingRule

All Implemented Interfaces:

JavaParserVisitor, net.sourceforge.pmd.lang.rule.ImmutableLanguage, net.sourceforge.pmd.properties.PropertySource, net.sourceforge.pmd.Rule

public class InefficientStringBufferingRule
extends AbstractJavaRule

How this rule works: find additive expressions: + check that the addition is between anything other than two literals if true and also the parent is StringBuffer constructor or append, report a violation.
