Class Summary

Class	Description
AbstractSuperCheck	Abstract class for checking that an overriding method with no parameters invokes the super method.
ArrayTrailingCommaCheck	Checks if array initialization contains optional trailing comma.
AvoidInlineConditionalsCheck	Detects inline conditionals.
CovariantEqualsCheck	Checks that if a class defines a covariant method equals, then it defines method equals(java.lang.Object).
DeclarationOrderCheck	Checks that the parts of a class or interface declaration appear in the order suggested by the Code Conventions for the Java Programming Language.
DefaultComesLastCheck	Check that the default is after all the cases in a switch statement.
EmptyStatementCheck	Detects empty statements (standalone ';').
EqualsAvoidNullCheck	Checks that any combination of String literals is on the left side of an equals() comparison.
EqualsHashCodeCheck	Checks that classes that either override equals() or hashCode() also overrides the other.
ExplicitInitializationCheck	Checks if any class or object member explicitly initialized to default for its type value (null for object references, zero for numeric types and char and false for boolean.
FallThroughCheck	Checks for fall through in switch statements Finds locations where a case contains Java code - but lacks a break, return, throw or continue statement.
FinalLocalVariableCheck	Ensures that local variables that never get their values changed, must be declared final.
HiddenFieldCheck	Checks that a local variable or a parameter does not shadow a field that is defined in the same class.
IllegalCatchCheck	Catching java.lang.Exception, java.lang.Error or java.lang.RuntimeException is almost never acceptable.
IllegalInstantiationCheck	Checks for illegal instantiations where a factory method is preferred.
IllegalThrowsCheck	Throwing java.lang.Error or java.lang.RuntimeException is almost never acceptable.
IllegalTokenCheck	Checks for illegal tokens.
IllegalTokenTextCheck	Checks for illegal token text.
IllegalTypeCheck	Checks that particular class are never used as types in variable declarations, return values or parameters.
InnerAssignmentCheck	Checks for assignments in subexpressions, such as in String s = Integer.toString(i = 2);.
MagicNumberCheck	Checks that there are no "magic numbers" where a magic number is a numeric literal that is not defined as a constant.
MissingCtorCheck	Checks that classes (except abstract one) define a ctor and don't rely on the default one.
MissingSwitchDefaultCheck	Checks that switch statement has "default" clause.
ModifiedControlVariableCheck	Check for ensuring that for loop control variables are not modified inside the for block.
MultipleStringLiteralsCheck	Checks for multiple occurrences of the same string literal within a single file.
MultipleVariableDeclarationsCheck	Checks that each variable declaration is in its own statement and on its own line.
NestedForDepthCheck	Check the number of nested for -statements.
NestedIfDepthCheck	Restricts nested if-else blocks to a specified depth (default = 1).
NestedTryDepthCheck	Restricts nested try-catch-finally blocks to a specified depth (default = 1).
NoCloneCheck	Checks that the clone method is not overridden from the Object class.
NoFinalizerCheck	Checks that no method having zero parameters is defined using the name finalize.
OneStatementPerLineCheck	Restricts the number of statements per line to one.
OverloadMethodsDeclarationOrderCheck	Checks that overload methods are grouped together.
PackageDeclarationCheck	Ensures there is a package declaration.
ParameterAssignmentCheck	Disallow assignment of parameters.
RequireThisCheck	Checks that code doesn't rely on the "this" default.
RequireThisCheck.CatchFrame	A frame initiated on entering a catch block; holds local catch variable names.
RequireThisCheck.ForFrame	A frame initiated on entering a for block; holds local for variable names.
ReturnCountCheck	Restricts the number of return statements in methods, constructors and lambda expressions (2 by default).
SimplifyBooleanExpressionCheck	Checks for overly complicated boolean expressions.
SimplifyBooleanReturnCheck	Checks for overly complicated boolean return statements.
StringLiteralEqualityCheck	Checks that string literals are not used with == or !=.
SuperCloneCheck	Checks that an overriding clone() method invokes super.clone().
SuperFinalizeCheck	Checks that an overriding finalize() method invokes super.finalize().
UnnecessaryParenthesesCheck	Checks if unnecessary parentheses are used in a statement or expression.
VariableDeclarationUsageDistanceCheck	Checks the distance between declaration of variable and its first usage.
