The class DataFilter has 13 public methods. Consider refactoring DataFilter to keep number of public methods under 10.
Open

class DataFilter extends Model
{
    const TYPE_INTEGER = 'integer';
    const TYPE_FLOAT = 'float';
    const TYPE_BOOLEAN = 'boolean';
Severity: Minor
Found in framework/data/DataFilter.php by phpmd

Since: PHPMD 0.1

A class with too many public methods is probably a good suspect for refactoring, in order to reduce its complexity and find a way to have more fine grained objects. By default it ignores methods starting with 'get' or 'set'.

The class DataFilter has 26 non-getter- and setter-methods. Consider refactoring DataFilter to keep number of methods under 25.

A class with too many methods is probably a good suspect for refactoring, in order to reduce its complexity and find a way to have more fine grained objects. By default it ignores methods starting with 'get' or 'set'. The default was changed from 10 to 25 in PHPMD 2.3.

The Weighted Method Count (WMC) of a class is a good indicator of how much time and effort is required to modify and maintain this class. The WMC metric is defined as the sum of complexities of all methods declared in a class. A large number of methods also means that this class has a greater potential impact on derived classes.

Example:

class Foo {
      public function bar() {
          if ($a == $b)  {
              if ($a1 == $b1) {
                  fiddle();
              } elseif ($a2 == $b2) {
                  fiddle();
              } else {
              }
          }
      }
      public function baz() {
          if ($a == $b) {
              if ($a1 == $b1) {
                  fiddle();
              } elseif ($a2 == $b2) {
                  fiddle();
              } else {
              }
          }
      }
      // Several other complex methods
  }

Cognitive Complexity

Cognitive Complexity is a measure of how difficult a unit of code is to intuitively understand. Unlike Cyclomatic Complexity, which determines how difficult your code will be to test, Cognitive Complexity tells you how difficult your code will be to read and comprehend.

A method's cognitive complexity is based on a few simple rules:

  • Code is not considered more complex when it uses shorthand that the language provides for collapsing multiple statements into one
  • Code is considered more complex for each "break in the linear flow of the code"
  • Code is considered more complex when "flow breaking structures are nested"

        A boolean flag argument is a reliable indicator for a violation of the Single Responsibility Principle (SRP). You can fix this problem by extracting the logic in the boolean flag into its own class or method.
