Class ClassPath.Entry

java.lang.Object
  org.netbeans.api.java.classpath.ClassPath.Entry

Enclosing class:: ClassPath

public final class ClassPath.Entry
extends Object
extends Object

Represents an individual entry in the ClassPath. An entry is a description of a folder, which is one of the ClassPath roots. Since the Entry does not control the folder's lifetime, the folder may be removed and the entry becomes invalid. It's also expected that ClassPath implementations may use other ClassPath entries as default or base for themselves, so Entries may be propagated between ClassPaths. Please note: This class is not intended to be implemented by regular clients. The project infrastructure and / or java language support modules should implement it and offer its services to others. Do not implement this class

public FileObject getRoot()

The method returns the root folder represented by the Entry. If the folder does not exist, or the folder is not readable, the method may return null.

Returns:: classpath entry root folder

isValid

public boolean isValid()

Returns:: true, iff the Entry refers to an existing and readable folder.

getError

public IOException getError()

Retrieves the error condition of the Entry. The method will return null, if the getRoot() would return a FileObject.

Returns:: error condition for this Entry or null if the Entry is OK.

getURL

public URL getURL()
