Method Detail

getLen

public long getLen()

isDir

public boolean isDir()

Is this a directory?

Returns:

true if this is a directory

getBlockSize

public long getBlockSize()

Get the block size of the file.

Returns:

the number of bytes

getReplication

public short getReplication()

Get the replication factor of a file.

Returns:

the replication factor of a file.

getModificationTime

public long getModificationTime()

Get the modification time of the file.

Returns:

the modification time of file in milliseconds since January 1, 1970 UTC.

getPath

public Path getPath()

write

public void write(DataOutput out)
           throws IOException

Description copied from interface: Writable

Serialize the fields of this object to out.

Specified by:

write in interface Writable

Parameters:

out - DataOuput to serialize this object into.

Throws:

IOException

readFields

public void readFields(DataInput in)
                throws IOException

Description copied from interface: Writable

Deserialize the fields of this object from in.

For efficiency, implementations should attempt to re-use storage in the existing object where possible.

Specified by:

readFields in interface Writable

Parameters:

in - DataInput to deseriablize this object from.

Throws:

IOException
