Method Detail

path

public IgfsPath path()

Gets path to file.

Specified by:

path in interface IgfsFile

Returns:

Path to file.

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.

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

Returns:

File group block size.

accessTime

public long accessTime()

Gets file last access time. File last access time is not updated automatically due to performance considerations and can be updated on demand with IgniteFileSystem.setTimes(IgfsPath, long, long) method.

By default last access time equals file creation time.

Specified by:

accessTime in interface IgfsFile

Returns:

Last access time.

modificationTime

public long modificationTime()

Gets file last modification time. File modification time is updated automatically on each file write and append.

Specified by:

modificationTime in interface IgfsFile

Returns:

Last modification time.

property

public String property(String name)
                throws IllegalArgumentException

Get file's property for specified name.

Specified by:

property in interface IgfsFile

Parameters:

name - Name of the property.

Returns:

File's property for specified name.

Throws:

IllegalArgumentException - If requested property was not found.

property

@Nullable
public @Nullable String property(String name,
                                           @Nullable
                                           @Nullable String dfltVal)

Get file's property for specified name.

Specified by:

property in interface IgfsFile

Parameters:

name - Name of the property.

dfltVal - Default value if requested property was not found.

Returns:

File's property for specified name.

properties

public Map<String,String> properties()

Get properties of the file.

Specified by:

properties in interface IgfsFile

Returns:

Properties of the file.

length

public long length()

Gets file's length.

Specified by:

length in interface IgfsFile

Returns:

File's length or zero for directories.
