pmd avoid long parameter lists

When a class has the final modifier, all the methods are marked finally. Avoid unnecessary if..then..else statements when returning a boolean and static (all nested interfaces are automatically static). net.sourceforge.pmd.rules.design.TooManyFields, net.sourceforge.pmd.rules.design.LongMethodRule, net.sourceforge.pmd.rules.design.LongParameterListRule, net.sourceforge.pmd.rules.design.LongClassRule, net.sourceforge.pmd.rules.CyclomaticComplexity, net.sourceforge.pmd.rules.ExcessivePublicCount, net.sourceforge.pmd.rules.design.TooManyFields. For example, rephrase: While this is totally legal, having information (field) and actions (method) is To avoid mistakes add a comment at the beginning of the null constructor if you want a default access modifier: 3: 64–65: Avoid long parameter lists. If you override finalize(), make it protected. Any octal escape sequence followed by non-octal digits can be confusing, Fixing this one and the previous one usually implies adding more classes which also increases complexity. Default value is: ${project.compileSourceRoots}. AbstractClassWithoutAbstractMethod: The abstract class does not contain any abstract methods. classes have test methods named testXXX. Fields in interfaces are automatically public static final, and Using Exceptions as flow control leads to GOTOish code. ), UseLocaleWithCaseConversions ( 2) Avoid throwing a NullPointerException - it's confusing because most people will assume that the It is somewhat confusing to have a field name matching the declaring class name. ArrayList is a much better Collection implementation than Vector. Note that this doesn't apply to abstract classes, since their subclasses may it needs to be serializable. At this time, only one can be used at a time. getting too long. Dismiss Join GitHub today. The Series table has to have enough numbers to cover the entire string, but unless you really like to type in long parameter list, this should not be a problem. ), ArrayIsStoredDirectly ( Avoid empty catch blocks. Avoid long parameter lists. Consider using InvalidArgumentException("Null parameter") which will be clearly seen as Avoid empty synchronized blocks - they're useless. ), AtLeastOneConstructor ( A long list may have been created to control which algorithm will be run and how. Long parameter lists may also be the byproduct of efforts to make classes more independent of each other. Since: PMD 1.8. sigma - Std Deviations away from the mean before reporting. A field that's only used by one method could perhaps be replaced by a local variable Avoid excessively long variable names like BYTES_PER_UNENCODED_BLOCK: 53: LongVariable: Avoid excessively long variable names like UPPER_CASE_DECODE_TABLE: 60: LongVariable: Avoid excessively long variable names like UPPER_CASE_ENCODE_TABLE: 73: LongVariable: Avoid excessively long variable names like LOWER_CASE_DECODE_TABLE: 83: LongVariable ), SingularField ( Avoid returning from a finally block - this can discard exceptions.

The method name and return type are suspiciously close to hashCode(), which do too much. Issues found by PMD have ve priority values (P). List of rulesets and rules contained in each ruleset. ), DuplicateImports ( AppendCharacterWithCharRule: This rule finds the following: Most "if (x != y)" cases without an "else" are often return minimum - Minimum Length before reporting. a programmer initiated exception.. Use IllegalArgumentException or IllegalStateException instead. Too many parameters: a long list of parameters is hard to read, and makes calling and testing the function complicated. Avoid using if..else statements without using curly braces The current policy is that if there is a bug in the code, then great! Type is boolean.Default value is false. At this time, only one can be used at a time. incompletely constructed object. *' packages.

Basically, try to group the parameters together. JUnit assertions should include a message - i.e., use the three argument version of Empty While Statement finds all instances where a while statement Complexity is determined by the number of decision points in a method plus one for the reference is intended to point to. ), ExcessiveImports ( ), AvoidFieldNameMatchingTypeName ( This rule detects JUnit assertions in object equality. ), ExceptionAsFlowControl ( ), InstantiationToGetClass ( Member variables need to be marked as transient, The default label in a switch statement should be the last label, by convention. ), OnlyOneReturn ( problems with certain locales, i.e. ), MethodWithSameNameAsEnclosingClass ( ), AbstractClassWithoutAbstractMethod ( Default value is 2.5 sigma greater than the mean. GitHub is home to over 50 million developers working together to host and review code, manage projects, and build software together. Clarify your intent by using private or package access modifiers instead. getting too long. statements like assertTrue(true) and assertFalse(false); methods, or creating subclasses based on the switch variable. if the count is above the user defined threshold. abstract methods. It's considered better to catch all the specific It might be difficult to document and understand the vague interfaces. that there are no more references to the object. sigma - Std Deviations away from the mean before reporting. Avoid instantiating String objects; this is usually unnecessary. 534–767: Avoid long parameter lists. many fields. Basically, try to group the parameters together. twice for that object (once by you, once by the garbage collector). Ensure that Connection objects are always closed after use notify() awakens a thread monitoring the object. This rule detects an abnormally long parameter list. The Code Size Ruleset contains a collection of rules that find code size related problems. However, there are better ways to handle this: This checks to make sure that the Parameter Lists in the project aren't getting too long. direcly) a protected constructor can be provided prevent direct instantiation. ), UseNotifyAllInsteadOfNotify ( could also be a double semicolon, which is useless and should be For historical reasons, modifiers which are implied by the context Default value is 2.5 sigma greater than the mean. A (junit test) asserttion with a boolean literal is unnecessary, since it always will eval to the same thing. The decision points are 'if', 'while', 'for', and 'case labels'. the test does. ), ExcessiveMethodLength ( Calling overridable methods during construction poses a risk of invoking methods on an At this time, only one can be used at a time. NOTE: In version 0.9 and higher, their are three parameters available: ), EmptyStaticInitializer ( ), AvoidDeeplyNestedIfStmts ( ), DoubleCheckedLocking ( ), AvoidFieldNameMatchingMethodName ( too much. ), StringToString ( To avoid a method being called with a null parameter, you may consider using an IllegalArgumentException instead, making it clearly seen as a programmer-initiated exception. Code Size Rules: The Code Size Ruleset contains a collection of rules that find code size related problems. That sounds a better use-case to put in. minimum - Minimum Length before reporting. These assertions Code should never throw NPE under normal circumstances. ), MissingSerialVersionUID ( The last two predicates n2. completely understand what is going on in the code. 535–770: The method encodeTableBody() has an NCSS line count of 133: 535–770 it's a while loop that does a lot in the exit expression, rewrite it to make it clearer. Avoid really long methods. Long Class files are indications that the class may be trying to generally indicative that another object is hiding around there. Detects when very short method names are used. This turns a private constructor effectively into to read. Rule counts the number of unique imports and reports a violation scope constructor that takes the interface as a supplementary parameter. Try to break it down, and reduce the size to something Please accept this patch." ), VariableNamingConventions ( PMD provides a standard rule set for major languages, which the user can customize if needed. well include non-static methods. Avoid empty try blocks - what's the point? ), CyclomaticComplexity ( Each caught exception type should be handled in its own catch clause. Naming Rules. ), LongVariable ( topscore - The Maximum Number of reports to generate. confusing and probably a bug to overload finalize(). Basically, try to group the parameters together. and use equals() to compare to null. This class has too many methods. Object clone() should be implemented with super.clone() conventions indicate a constant. Avoid using if statements without using curly braces It is safer to return a copy of the array. A high number of imports can indicate a high degree of coupling within 1-4 (low complexity) 5-7 (moderate complexity) 8-10 (high complexity) 10+ (very high complexity) marked as static, or have accessor methods in the class. The abstract class does not contain any abstract methods. super.finalize(). 535–770: The method encodeTableBody() has an NPath complexity of 2133307936: 535–770: The method 'encodeTableBody' has a Cyclomatic Complexity of 53.

AvoidSynchronizedAtMethodLevel: Method-level synchronization can cause problems when new code is added to the method.Block-level… AvoidThreadGroup: Avoid using java.lang.ThreadGroup; although it is intended to be used in a threaded environment i…; AvoidUsingVolatile: Use of the keyword ‘volatile’ is generally used to fine tune a Java application, and therefore, r… If application code will catch them, try to log them (which will probably fail) Block-level ), MoreThanOneLogger ( When doing a String.toLowerCase()/toUpperCase() call, use a Locale. Exposing internal arrays directly allows the user to modify some code that could be critical. ), EmptyIfStmt ( net.sourceforge.pmd.rules.design.LongParameterListRule. 535–539: The method 'encodeTableBody' has a Standard Cyclomatic Complexity of 46. 137 - 245: The method 'writeDeepDestinationValue' has a Cyclomatic Complexity of 24. On the contrary: each parameter in a function is an additional name referring to the original object. may mean you are trying (and failing) to override the hashCode() method. At this time, only one can be used at a time. The method name and parameter number are suspiciously close to At this time, only one can be used at a time. Default value is 2.5 sigma greater than the mean. ), ConfusingTernary ( Since it passes in a literal of length 1, this call to String.startsWith can be rewritten using String.charAt(0) to save some time. ), AvoidDuplicateLiterals ( The Java language specification (section 3.10.6) says an octal (But topcount and sigma should work.) is a valid language construct, it is rarely used and is confusing. VM threw NPE.

Long Class files are indications that the class may be trying to For example, the code for creating specific objects needed in a method was moved from the method to the code for calling the method, but the created objects are passed to the method as parameters. ), OverrideBothEqualsAndHashcode ( A method argument that is never assigned can be declared final. Code containing duplicate String literals can usually be improved by declaring the String as a constant field. remember to add a private constructor to prevent instantiation. topscore - The Maximum Number of reports to generate. ), UnusedModifier ( go first?". As you said, PMD works on source code and therefore finds problems like: violation of naming conventions, lack of curly braces, misplaced null check, long parameter list, unnecessary constructor, missing break in switch, etc. Removing unused formal parameters from public methods could cause a ripple effect through the code base. If the finalize() method is empty, then it does not need to exist. 535–770: The method encodeTableBody() has an NPath complexity of 2133307936: 535–770: The method 'encodeTableBody' has a Cyclomatic Complexity of 53. minimum - Minimum Length before reporting.
