Class ClasspathJarSets

java.lang.Object
com.atlassian.confluence.util.classpath.ClasspathJarSets
All Implemented Interfaces:
DuplicateClassFinder
public class ClasspathJarSets extends Object implements DuplicateClassFinder
Contains a set of JAR files for each class on the classpath: the set of JARs that contain the class.

Ideally, a set of JARs for a given class should only include one JAR; if the set of JARs for a given class includes more than one JAR, the class is duplicated in several JARs in the classpath.

  • Method Details

    • addClass

      public void addClass(String classFileName, JarSet jars)

    • getJarSetsWithCommonClasses

      public Set<JarSet> getJarSetsWithCommonClasses()
      Specified by:
      getJarSetsWithCommonClasses in interface DuplicateClassFinder
      Returns:
      the sets of JARs which have classes in common, i.e. any JarSet containing more than one JAR

    • getClassFileNames

      public SortedSet<String> getClassFileNames(JarSet jars)
      Returns the class files in a given set of JARs, which may be one or more JARs.

      The set is sorted by the natural order of the contents: the String class file names.

      Specified by:
      getClassFileNames in interface DuplicateClassFinder
      Parameters:
      jars - a set of one or more JARs on the classpath
      Returns:
      the class files in the JarSet. Each is a String in the form "java/lang/String.class". Returns an empty set if no classes are in that JarSet.

    • getPackageNames

      public SortedSet<String> getPackageNames(JarSet jars)
      Returns the packages in a given set of JARs, which may be one or more JARs. Each package is in the form "java/lang".

      The set is sorted by the natural order of the contents: the String package names.

      Specified by:
      getPackageNames in interface DuplicateClassFinder
      Parameters:
      jars - a set of one or more JARs on the classpath
      Returns:
      the packages found in the JarSet. Each is a String in the form "java/lang". Returns an empty set if no classes are in that JarSet.

    • getClassNames

      public SortedSet<String> getClassNames(JarSet jars)
      Specified by:
      getClassNames in interface DuplicateClassFinder
