Class Summary

Class	Description
AbstractOptimizationRule	Base class with utility methods for optimization rules
AppendCharacterWithCharRule	This rule finds the following:
AvoidInstantiatingObjectsInLoopsRule
BigIntegerInstantiationRule	Rule that marks instantiations of new BigInteger or BigDecimal objects, when there is a well-known constant available, such as BigInteger.ZERO.
BooleanInstantiationRule	Avoid instantiating Boolean objects; you can reference Boolean.TRUE, Boolean.FALSE, or call Boolean.valueOf() instead.
ConsecutiveAppendsShouldReuseRule	Original rule was written with XPath, but didn't verify whether the two calls to append would have been done on the same variable.
ConsecutiveLiteralAppendsRule	This rule finds concurrent calls to StringBuffer/Builder.append where String literals are used It would be much better to make these calls using one call to .append
InefficientEmptyStringCheckRule	This rule finds code which inefficiently determines empty strings.
InefficientStringBufferingRule	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.
InsufficientStringBufferDeclarationRule	This rule finds StringBuffers which may have been pre-sized incorrectly.
RedundantFieldInitializerRule	Detects redundant field initializers, i.e.
StringInstantiationRule
StringToStringRule
UnnecessaryWrapperObjectCreationRule
UseIndexOfCharRule
UselessStringValueOfRule
UseStringBufferForStringAppendsRule
UseStringBufferLengthRule	This rule finds places where StringBuffer.toString() is called just to see if the string is 0 length by either using .equals("") or toString().length().
