public abstract class ClassEntry
extends Object

A ClassEntry represents a single class file within one classes directory or .jar file. It's linked to the ClassPackage it belongs to.

Constructor Detail

ClassEntry

protected ClassEntry(String classname,
                     ClassPackage pckg)

Method Detail

getClassname

public String getClassname()

Returns:

the full qualified classname

getShortName

public String getShortName()

Returns:

the classname without package prefix

getClassfile

public ClassFile getClassfile()

Resolves the ClassFile by analyzing the byte code. This is a time-consuming operation and should be called as late as possible. For .jar files the most time is spent by decompressing the .class file. The result will be cached for further calls.

Returns:

a cached or freshly resolved instance of the ClassFile

resolveClassFile

protected abstract ClassFile resolveClassFile()

getPackage

public ClassPackage getPackage()

Returns:

the ClassPackage this ClassEntry belongs to.

getAlternatives

public List<ClassEntry> getAlternatives()

Returns a list of all other .class files with the same fully qualified name.

Returns:

the other .class files or null if there are none

getAlternativesWithinSamePackage

public List<ClassEntry> getAlternativesWithinSamePackage()

Returns a list of all other .class files with the same fully qualified name with the same ClassRoot. Such .class files exist within multi-release JAR files within the META-INF/versions directory.

Returns:

all other versions of the same .class file or an empty list if there are none

getURI

public abstract URI getURI()

Returns:

an URI which identifies the .class file uniquely
