TPath

```
@Immutable
public final class TPath
extends java.lang.Object
implements java.nio.file.Path, TRex
```
A Path implementation for use with NIO.2. Applications should directly instantiate this class to overcome the restrictions of the file system provider service location in the NIO.2 API for JSE 7. Once created, it's safe to use TPath instances polymorphically as Path instances.
Objects of this class are immutable and inherently volatile because all virtual file system state is managed by the TrueVFS Kernel module.
You should never use object identity ('==') to test for equality of objects of this class with another object. Use the method equals(Object) instead.
Unless otherwise noted, you should not assume that calling the same method on an instance of this class multiple times will return the same object.
Unless otherwise noted, when an instance of this class is created, the resulting path name gets scanned for prospective archive files using the current archive detector TConfig.current().getArchiveDetector(). To change this, wrap the object creation in a code block which pushes a temporary configuration on the inheritbale thread local stack of configurations as follows:
```
 // Create reference to the current directory.
 TPath directory = new TPath("");
 // This is how you would detect a prospective archive file, supposing
 // the JAR of the module TrueVFS Driver ZIP is present on the run time
 // class path.
 TPath archive = directory.resolve("archive.zip");
 TPath file;
 try (TConfig config = TConfig.open()) {
     config.setArchiveDetector(TArchiveDetector.NULL);
     // Ignore prospective archive file here.
     file = directory.resolve("archive.zip");
 }
 // Once created, the prospective archive file detection does not change
 // because a TPath is immutable.
 assert archive.getArchiveDetector() == TArchiveDetector.ALL;
 assert archive.isArchive();
 assert file.getArchiveDetector() == TArchiveDetector.NULL;
 assert !file.isArchive();
 
```
Mind that you should either use archive or file from the previous example to do any subsequent I/O - but not both - so that you don't bypass or corrupt the state which gets implicitly associated with any archive file by the TrueVFS Kernel module!

```
public TPath(java.lang.String first,
             java.lang.String... more)
```
    Constructs a new path from the given path strings.
    The supported path name separators are "File.separator" and "/". Any trailing separators in the resulting path name get discarded.
    This constructor scans the path name resulting from the segment parameters to detect prospective archive files using the current archive detector TConfig.current().getArchiveDetector().
    Examples
    
    On all platforms:
    
    Relative path name:
    
    Path path = new TPath("app.war/WEB-INF/lib", "lib.jar/META-INF/MANIFEST.MF");
    
    On POSIX platforms (Unix, Linux, Mac OS X):
    
    Absolute path name:
    
    Path path = new TPath("/home/christian/archive.zip");
    
    On the Windows platform:
    
    Relative path name:
    
    Path path = new TPath("app.war\WEB-INF\lib", "lib.jar\META-INF\MANIFEST.MF");
    
    Absolute path name with C: drive letter and wierd case letters:
    
    Path path = new TPath("c:\UsErS\cHrIsTiAn\ArChIvE.zIp");
    
    Absolute path name with separated UNC host and share name and forward slash separator:
    
    Path path = new TPath("//host", "share", "archive.zip");
    
    Dito with mixed slash separators:
    
    Path path = new TPath("\\host/share\archive.zip");
    
    Parameters:
    
    first - the first sub path string.
    
    more - optional sub path strings.
  - TPath
```
public TPath(java.net.URI name)
```
    Constructs a new path from the given hierarchical URI.
    If the scheme component of the URI is undefined and the scheme specific part does not start with a "/", then the URI gets resolved against the "file:" based URI for the current directory in the platform file system. Otherwise, if the scheme component is undefined, then the URI gets resolved against the URI "file:/".
    This constructor scans the path component of the URI to detect prospective archive files using the current archive detector TConfig.current().getArchiveDetector().
    Examples
    
    On all platforms:
    
    Relative URI with relative path component:
    
    Path path = new TPath(new URI("app.war/WEB-INF/lib/lib.jar/META-INF/MANIFEST.MF"));
    
    HTTP URI:
    
    Path path = new TPath(new URI("http://acme.com/download/everything.tar.gz/README.TXT"));
    
    On POSIX platforms (Unix, Linux, Mac OS X):
    
    Relative URI with absolute path component:
    
    Path path = new TPath(new URI("/home/christian/archive.zip"));
    
    Dito with absolute, hierarchical URI:
    
    Path path = new TPath(new URI("file:/home/christian/archive.zip"));
    
    On the Windows platform:
    
    Relative URI with relative path component with C: drive letter and following absolute path name:
    
    Path path = new TPath(new URI("c%3A/Users/christian/archive.zip"));
    
    Dito with absolute, hierarchical URI:
    
    Path path = new TPath(new URI("file:/c:/Users/christian/archive.zip"));
    
    Relative URI with UNC host and share name:
    
    Path path = new TPath(new URI("//host/share/archive.zip"));
    
    Dito with absolute, hierarchical URI:
    
    Path path = new TPath(new URI("file://host/share/archive.zip"));
    
    Parameters:
    
    name - the path name. This must be a hierarchical URI with an undefined fragment component. Any trailing separators in the path component get discarded.
    
    Throws:
    
    java.lang.IllegalArgumentException - if the preconditions for the parameter do not hold.
  - TPath
```
public TPath(java.io.File file)
```
    Constructs a new path from the given file.
    This constructor is required for interoperability with the TFile class because it does not support TFile.toPath().
    If file is an instance of TFile, its archive detector and file system node path get shared with this instance.
    Otherwise, this constructor scans the path name of the file to detect prospective archive files using the current archive detector TConfig.current().getArchiveDetector().
    Examples
    
    On all platforms:
    
    Relative path name:
    
    Path path = new TPath(new File("app.war/WEB-INF/lib", "lib.jar/META-INF/MANIFEST.MF"));
    
    On POSIX platforms (Unix, Linux, Mac OS X):
    
    Absolute path name with plain File:
    
    Path path = new TPath(new File("/home/christian/archive.zip"));
    
    Absolute path name with plain TFile:
    
    Path path = new TPath(new TFile("/home/christian/archive.zip"));
    
    On the Windows platform:
    
    Absolute path name with plain File:
    
    Path path = new TPath(new File("c:\home\christian\archive.zip"));
    
    Absolute path name with TFile:
    
    Path path = new TPath(new TFile("c:\home\christian\archive.zip"));
    
    Parameters:
    
    file - a file. If this is an instance of TFile, its archive detector and file system node path get shared with this instance.
  - TPath
```
public TPath(java.nio.file.Path path)
```
    Constructs a new path from the given path.
    This constructor scans the path name of the given path to detect prospective archive files using the current archive detector TConfig.current().getArchiveDetector().
    Examples
    
    On all platforms:
    
    Relative path name:
    
    Path path = new TPath(Paths.current("app.war/WEB-INF/lib", "lib.jar/META-INF/MANIFEST.MF"));
    
    Parameters:
    
    path - a path.

public TPath toNonArchivePath()
```
    Returns a path object for the same path name, but does not detect any archive file name patterns in the last path name segment. The parent path object is unaffected by this transformation, so the path name of this path object may address an entry in an archive file.

    Returns:
    
    A path object for the same path name, but does not detect any archive file name patterns in the last path name segment.
