Constructor Detail

IgfsFileImpl

public IgfsFileImpl()

Empty constructor required by Externalizable.

IgfsFileImpl

public IgfsFileImpl(IgfsPath path,
            IgfsFileInfo info,
            long globalGrpBlockSize)

Constructs directory info.

Parameters:

path - Path.

IgfsFileImpl

public IgfsFileImpl(IgfsPath path,
            IgfsListingEntry entry,
            long globalGrpSize)

Constructs file instance.

Parameters:

path - Path.

entry - Listing entry.

Method Detail

path

public IgfsPath path()

Gets path to file.

Specified by:

path in interface IgfsFile

Returns:

Path to file.

fileId

public IgniteUuid fileId()

Returns:

File ID.

isFile

public boolean isFile()

Check this file is a data file.

Specified by:

isFile in interface IgfsFile

Returns:

True if this is a data file.

isDirectory

public boolean isDirectory()

Check this file is a directory.

Specified by:

isDirectory in interface IgfsFile

Returns:

True if this is a directory.

length

public long length()

Gets file's length.

Specified by:

length in interface IgfsFile

Returns:

File's length or zero for directories.

blockSize

public int blockSize()

Gets file's data block size.

Specified by:

blockSize in interface IgfsFile

Returns:

File's data block size or zero for directories.

groupBlockSize

public long groupBlockSize()

Gets file group block size (i.e. block size * group size).

Specified by:

groupBlockSize in interface IgfsFile
