Package org.epics.archiverappliance.utils.nio

Class ArchPaths

java.lang.Object

org.epics.archiverappliance.utils.nio.ArchPaths

All Implemented Interfaces:

Closeable, AutoCloseable

public class ArchPaths
extends Object
implements Closeable

This is a replacement for NIO Paths that caters to our syntax rules. Normal file system paths are all similar to linux file names. The compressed use the jar:file:syntax. For example, jar:file:///ziptest/alltext.zip!/SomeTextFile.txt

Parameters:

path - Path

options - OpenOption

Returns:

a new seekabel byte channel

Throws:

IOException -
