All Implemented Interfaces:

public class GcpFileSystemProvider extends Object implements FileSystemProvider
Provides services to access Google Cloud Storage as a file system.

  • Constructor Details

    • GcpFileSystemProvider

      public GcpFileSystemProvider()
      Create an instance of the GCP filesystem provider.

  • Method Details

    • getInstance

      public static GcpFileSystemProvider getInstance()

    • 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 client, 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:
      client - 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

    • 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

    • 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

    • 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
