        Package names to ignore.

      • BRACKET_PATTERN

        private static final java.util.regex.Pattern BRACKET_PATTERN
        Pattern to match brackets in a full type name.

      • excludeClassesRegexps

        private final java.util.List<java.util.regex.Pattern> excludeClassesRegexps
        Specify user-configured regular expressions to ignore classes.

      • importedClassPackages

        private final java.util.Map<java.lang.String,​java.lang.String> importedClassPackages
        A map of (imported class name -> class name with package) pairs.

      • excludedClasses

        private java.util.Set<java.lang.String> excludedClasses
        Specify user-configured class names to ignore.

      • excludedPackages

        private java.util.Set<java.lang.String> excludedPackages
        Specify user-configured packages to ignore. All excluded packages should end with a period, so it also appends a dot to a package name.

      • max

        private int max
        Specify the maximum threshold allowed.

      • packageName

        private java.lang.String packageName
        Current file package.

    • Constructor Detail

      • AbstractClassCouplingCheck

        protected AbstractClassCouplingCheck​(int defaultMax)
        Creates new instance of the check.
        Parameters:
        defaultMax - default value for allowed complexity.

    • Method Detail

      • getLogMessageId

        protected abstract java.lang.String getLogMessageId()
        Returns message key we use for log violations.
        Returns:
        message key we use for log violations.

      • setMax

        public final void setMax​(int max)
        Setter to specify the maximum threshold allowed.
        Parameters:
        max - allowed complexity.

      • setExcludedClasses

        public final void setExcludedClasses​(java.lang.String... excludedClasses)
        Setter to specify user-configured class names to ignore.
        Parameters:
        excludedClasses - classes to ignore.

      • setExcludeClassesRegexps

        public void setExcludeClassesRegexps​(java.lang.String... from)
        Setter to specify user-configured regular expressions to ignore classes.
        Parameters:
        from - array representing regular expressions of classes to ignore.

      • setExcludedPackages

        public final void setExcludedPackages​(java.lang.String... excludedPackages)
