Class ClasspathJarSets

java.lang.Object
  com.atlassian.confluence.util.classpath.ClasspathJarSets

All Implemented Interfaces:

DuplicateClassFinder

public class ClasspathJarSets
extends java.lang.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.

                     JarSet jars)

getJarSetsWithCommonClasses

public java.util.Set 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 java.util.SortedSet 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 java.util.SortedSet 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.
