@Deprecated
public TFileSystemProvider()
```
    Deprecated. Do NOT call this constructor directly!
    
    Constructs a new TrueZIP file system provider which is identified by the URI scheme "tpath" for accessing any path within the root mount point URI "file:/".
    Do NOT call this constructor directly - it's solely provided in order to use this file system provider class with the service location feature of the NIO.2 API!

private TFileSystemProvider(String scheme,
                   URI root)
```
- Method Detail
  - get
```
static TFileSystemProvider get(URI name)
```
    Obtains a file system provider for the given TPath URI.
    
    Parameters:
    name - a TPath URI.
    
    Returns:
    A file system provider.
  - umount
```
public static void umount()
                   throws FsSyncException
```
    Commits all unsynchronized changes to the contents of all federated file systems (i.e. prospective archive files) to their respective parent file system, releases the associated resources (i.e. target archive files) for access by third parties (e.g. other processes), cleans up any temporary allocated resources (e.g. temporary files) and purges any cached data. Note that temporary files may get used even if the archive files where accessed read-only.
    
    Throws:
    
    FsSyncWarningException - if only warning conditions occur. This implies that the respective parent file system has been updated with constraints, such as a failure to set the last modification time of the entry for the federated file system (i.e. archive file) in its parent file system.
    
    FsSyncException - if any error conditions occur. This implies loss of data!
  - getScheme
```
public String getScheme()
```
    Returns the default scheme of this provider.
    
    Specified by:
    
    getScheme in class java.nio.file.spi.FileSystemProvider
    
    Returns:
    the default scheme of this provider.
  - getRoot
```
public FsPath getRoot()
```
    Returns the root mount point of this provider.
    
    Returns:
    The root mount point of this provider.

  - newFileSystem
```
public TFileSystem newFileSystem(java.nio.file.Path path,
                        Map<String,?> configuration)
```
    Scans the given path for prospective archive files using the given configuration and returns the file system for the innermost prospective archive file or throws an UnsupportedOperationException if no prospective archive file is detected.
    First, the configuration TFileSystemProvider.Parameters get enumerated. If no value is set for a parameter key, the respective value of the current configuration gets used.
    Next, the path is scanned for prospective archive files using the configuration resulting from the first step. If one or more prospective archive files are found, the file system for the innermost prospective archive file is returned. Otherwise, an UnsupportedOperationException is thrown.
    
    Overrides:
    
    newFileSystem in class java.nio.file.spi.FileSystemProvider
    
    Parameters:
    path - the path to scan for prospective archive files.
    configuration - may contain a TArchiveDetector for the key TFileSystemProvider.Parameter.ARCHIVE_DETECTOR.
    
    Returns:
    the file system for the innermost prospective archive file.
    
    Throws:
    
    UnsupportedOperationException - if no prospective archive file has been detected according to the configuration resulting from merging the given configuration with the current configuration.
  - newFileSystem
```
public TFileSystem newFileSystem(URI uri,
                        Map<String,?> configuration)
```
    Returns a file system for the given hierarchical TPath uri.
    First, the configuration TFileSystemProvider.Parameters get enumerated. If no value is set for a parameter key, the respective value of the current configuration gets used.
    Next, the uri is scanned for prospective archive files using the configuration resulting from the first step. Any trailing separators in uri get discarded. If one or more prospective archive files are found, the file system for the innermost prospective archive file is returned. Otherwise, the file system for the innermost directory is returned.
    
    Specified by:
    
    newFileSystem in class java.nio.file.spi.FileSystemProvider
    
    Parameters:
    uri - the TPath uri to return a file system for.
    configuration - may contain a TArchiveDetector for the key TFileSystemProvider.Parameter.ARCHIVE_DETECTOR.
    
    Returns:
    the file system for the innermost prospective archive file or directory.
    
    Throws:
    
    IllegalArgumentException - if the given uri is opaque.
  - getFileSystem
```
public TFileSystem getFileSystem(URI uri)
```
    Returns a file system for the given hierarchical TPath uri.
    The uri is scanned for prospective archive files using the current configuration. Any trailing separators in uri get discarded. If one or more prospective archive files are found, the file system for the innermost prospective archive file is returned. Otherwise, the file system for the innermost directory is returned.
    
    Specified by:
    
    getFileSystem in class java.nio.file.spi.FileSystemProvider
    
    Parameters:
    uri - the TPath uri to return a file system for.

    the file system for the innermost prospective archive file or directory.
    
    Throws:
    
    IllegalArgumentException - if the given uri is opaque.
  - getFileSystem
```
TFileSystem getFileSystem(TPath path)
```
    Obtains a file system for the given path. If a file system doesn't exist yet, it's created.
    
    Parameters:
    path - a path.
    
    Returns:
    A file system.
  - getPath
```
public TPath getPath(URI name)
```
    Returns a TPath for the given hierarchical name.
    The URI path component is scanned for prospective archive files using the current configuration. Any trailing separators in name get discarded.
    
    Specified by:
    
    getPath in class java.nio.file.spi.FileSystemProvider
    
    Parameters:
    name - the uri to return a TPath for.
