Constructor Detail

GridFilesystem

public GridFilesystem(Cache<String,byte[]> data,
                      Cache<String,GridFile.Metadata> metadata,
                      int defaultChunkSize)

Deprecated.

Creates an instance. The data and metadata caches should already have been setup and started

Parameters:

data - the cache where the actual file contents are stored

metadata - the cache where file meta-data is stored

defaultChunkSize - the default size of the file chunks

GridFilesystem

public GridFilesystem(Cache<String,byte[]> data,
                      Cache<String,GridFile.Metadata> metadata)

Deprecated.

Method Detail

getFile

public File getFile(String pathname)

Deprecated.

Returns the file denoted by pathname.

Parameters:

pathname - the full path of the requested file

Returns:

the File stored at pathname

getFile

public File getFile(String pathname,
                    int chunkSize)

Deprecated.

Returns the file denoted by pathname. If the file does not yet exist, it is initialized with the given chunkSize. However, if the file at pathname already exists, the chunkSize parameter is ignored and the file's actual chunkSize is used.

Parameters:

pathname - the full path of the requested file

chunkSize - the size of the file's chunks. This parameter is only used for non-existing files.

Returns:

the File stored at pathname

getFile

public File getFile(String parent,
                    String child)

Deprecated.

getFile

public File getFile(String parent,
                    String child,
                    int chunkSize)

Deprecated.

getFile

public File getFile(File parent,
                    String child)

Deprecated.

getFile

public File getFile(File parent,
                    String child,
                    int chunkSize)

Deprecated.

getOutput

public OutputStream getOutput(String pathname)
                       throws IOException

Deprecated.

Opens an OutputStream for writing to the file denoted by pathname. If a file at pathname already exists, writing to the returned OutputStream will overwrite the contents of the file.

Parameters:

pathname - the path to write to

Returns:

an OutputStream for writing to the file at pathname

Throws:

IOException - if an error occurs

getOutput

public OutputStream getOutput(String pathname,
                              boolean append)
                       throws IOException

Deprecated.

Opens an OutputStream for writing to the file denoted by pathname. The OutputStream can either overwrite the existing file or append to it.

Parameters:

pathname - the path to write to

append - if true, the bytes written to the OutputStream will be appended to the end of the file. If false, the bytes will overwrite the original contents.

Returns:

an OutputStream for writing to the file at pathname

Throws:

IOException - if an error occurs

getOutput

public OutputStream getOutput(String pathname,
                              boolean append,
                              int chunkSize)
                       throws IOException

Deprecated.

Opens an OutputStream for writing to the file denoted by pathname.

Parameters:

pathname - the file to write to

append - if true, the bytes written to the OutputStream will be appended to the end of the file

chunkSize - the size of the file's chunks. This parameter is honored only when the file at pathname does not yet exist. If the file already exists, the file's own chunkSize has precedence.

Returns:

the OutputStream for writing to the file

Throws:

IOException - if the file is a directory, cannot be created or some other error occurs

getOutput

public OutputStream getOutput(GridFile file)
                       throws IOException

Deprecated.

Opens an OutputStream for writing to the given file.

Parameters:

file - the file to write to

Returns:

an OutputStream for writing to the file

Throws:

IOException - if an error occurs

getInput

public InputStream getInput(String pathname)
                     throws FileNotFoundException

Deprecated.

Opens an InputStream for reading from the file denoted by pathname.

Parameters:

pathname - the full path of the file to read from

Returns:

an InputStream for reading from the file

Throws:

FileNotFoundException - if the file does not exist or is a directory

getInput

public InputStream getInput(File file)
                     throws FileNotFoundException

Deprecated.

Opens an InputStream for reading from the given file.

Parameters:

file - the file to open for reading

Returns:

an InputStream for reading from the file

Throws:

FileNotFoundException - if the file does not exist or is a directory

getReadableChannel

public ReadableGridFileChannel getReadableChannel(String pathname)
                                           throws FileNotFoundException

Deprecated.

Opens a ReadableGridFileChannel for reading from the file denoted by the given file path. One of the benefits of using a channel over an InputStream is the possibility to randomly seek to any position in the file (see #ReadableGridChannel.position()).

Parameters:

pathname - path of the file to open for reading

Returns:

a ReadableGridFileChannel for reading from the file

Throws:

FileNotFoundException - if the file does not exist or is a directory

getWritableChannel

public WritableGridFileChannel getWritableChannel(String pathname)
                                           throws IOException

Deprecated.

Opens a WritableGridFileChannel for writing to the file denoted by pathname. If a file at pathname already exists, writing to the returned channel will overwrite the contents of the file.

Parameters:

pathname - the path to write to

Returns:

a WritableGridFileChannel for writing to the file at pathname

Throws:

IOException - if an error occurs

getWritableChannel

public WritableGridFileChannel getWritableChannel(String pathname,
                                                  boolean append)
                                           throws IOException

Deprecated.

Opens a WritableGridFileChannel for writing to the file denoted by pathname. The channel can either overwrite the existing file or append to it.

Parameters:

pathname - the path to write to

append - if true, the bytes written to the WritableGridFileChannel will be appended to the end of the file. If false, the bytes will overwrite the original contents.

Returns:

a WritableGridFileChannel for writing to the file at pathname

Throws:

IOException - if an error occurs

getWritableChannel

public WritableGridFileChannel getWritableChannel(String pathname,
                                                  boolean append,
                                                  int chunkSize)
                                           throws IOException

Deprecated.

Opens a WritableGridFileChannel for writing to the file denoted by pathname.

Parameters:

pathname - the file to write to

append - if true, the bytes written to the channel will be appended to the end of the file

chunkSize - the size of the file's chunks. This parameter is honored only when the file at pathname does not yet exist. If the file already exists, the file's own chunkSize has precedence.

Returns:

a WritableGridFileChannel for writing to the file

Throws:

IOException - if the file is a directory, cannot be created or some other error occurs
