All Implemented Interfaces:

FileSystemProvider
```
public class BuiltinStreamProvider
extends Object
implements FileSystemProvider
```
Provides access to built-in data streams. There are three schemes provided for acessing built-in stream:
- stdin provides access to the standard nput stream (System.in) of the executing process.
- stdout provides access to the standard output stream (System.out of the executing process.
- stderr provides access to the standard error stream of the executing process.
The built-in streams do not support hierarchical paths; it is not considered an error to provide additional data in the path beyond the scheme, but it will be ignored.

Method Summary

All Methods Instance Methods Concrete Methods
Modifier and Type	Method	Description
`FileConfiguration`	`getConfigurationTemplate()`	Returns a non-populated configuration object to server as a template that the user must fill-in.
`Map<String,FileConfiguration>`	`getDefaultConfiguration()`	Gets default configuration for the schemes handled by the provider.
`FileSystem`	`getFileSystem(FileClient fileClient, FileConfiguration configuration, Path path)`	Gets the file system identified by the path.
`Path`	`getFileSystemPath(Path path)`	Returns the filesystem root path associated with the given path.
`Path`	`getPath(String path)`	Gets the path identified by the given string.
`boolean`	`isPathSupported(String path)`	Indicates whether the given scheme is handled by the provider.

```
public BuiltinStreamProvider()
```
    Creates a new provider for built-in streams.
    This constructor is public as a matter of implementation only. Users should not construct a provider directly, but instead use the static methods contained in FileClient and Paths.
- Method Detail
  - isPathSupported
```
public boolean isPathSupported(String path)
```
    Description copied from interface: FileSystemProvider
    
    Indicates whether the given scheme is handled by the provider.
    
    Specified by:
    
    isPathSupported in interface FileSystemProvider
    
    Parameters:
    
    path - an identifier for a path scheme
    
    Returns:
    
    true if this provider handles paths using the scheme, false otherwise.
  - getFileSystem
```
public FileSystem getFileSystem(FileClient fileClient,
                                FileConfiguration configuration,
                                Path path)
```
    Description copied from interface: FileSystemProvider
    
    Gets the file system identified by the path. The path identifies a file on the file system; the file's file system is returned. This is equivalent to calling getPath(path).getFileSystem(), but may be faster.
    
    Specified by:
    
    getFileSystem in interface FileSystemProvider
    
    Parameters:
    
    fileClient - a file client. most implementations will ignore this parameter. "meta-filesystems" ( those than can span filesystems ) may need the file client.
    
    configuration - the configuration for this filesystem
    
    path - a path identifying a file on the file system
    
    Returns:
    
    the requested file system object
  - getPath
```
public Path getPath(String path)
```
    Description copied from interface: FileSystemProvider
    
    Gets the path identified by the given string. The resulting path represents a location in an abstract file system. Use the methods in FileClient to perform operations on the files and directories represented by paths.
    
    Specified by:
    
    getPath in interface FileSystemProvider
    
    Parameters:
    
    path - the path name to resolve into a path object
    
    Returns:
    
    the requested path object
  - getFileSystemPath
```
public Path getFileSystemPath(Path path)
```
    Description copied from interface: FileSystemProvider
    
    Returns the filesystem root path associated with the given path.
    
    Specified by:
    
    getFileSystemPath in interface FileSystemProvider
    
    Parameters:
    
    path - the path
    
    Returns:
    
    the root path
  - getConfigurationTemplate
```
public FileConfiguration getConfigurationTemplate()
```
    Description copied from interface: FileSystemProvider
    
    Returns a non-populated configuration object to server as a template that the user must fill-in.
    
    Specified by:
    
    getConfigurationTemplate in interface FileSystemProvider
    
    Returns:
    
    a configuration template
  - getDefaultConfiguration
```
public Map<String,FileConfiguration> getDefaultConfiguration()
```
    Description copied from interface: FileSystemProvider
    
    Gets default configuration for the schemes handled by the provider. Default configuration is inherited from the execution environment.
    A provider should return a map with entries only for schemes having default configuration; if no schemes do, an empty map should be returned.
    
    Specified by:
    
    getDefaultConfiguration in interface FileSystemProvider
    
    Returns:
    
    a mapping of schemes to default configuration
