Constructor Detail

BlobDataCell.BlobAddress

BlobDataCell.BlobAddress(int bufferID,
                         int column,
                         boolean isUseCompression)

Create new address object.

Parameters:

bufferID - ID of corresponding buffer.

column - The column index

isUseCompression - Whether or not the file is to be compressed.

Method Detail

setIndexOfBlobInColumn

public void setIndexOfBlobInColumn(int indexOfBlobInColumn)

Set the corresponding address.

Parameters:

indexOfBlobInColumn - The index of blob in the column.

getBufferID

int getBufferID()

Returns:

The ID of the Buffer which takes responsibility to serialize out this object

getColumn

int getColumn()

Returns:

the column

isUseCompression

public boolean isUseCompression()

Returns:

Whether or not the blob is (to be) compressed.

getIndexOfBlobInColumn

int getIndexOfBlobInColumn()

Get the index of the blob in the columns (if a column only contains blobs, this method returns the row index).

Returns:

The blob row address

toString

public String toString()

Overrides:

toString in class Object

serialize

void serialize(DataOutput output)
         throws IOException

Writes address to a stream.

Parameters:

output - To write to.

deserialize

static BlobDataCell.BlobAddress deserialize(DataInput input)
                                     throws IOException

Reads blob address from stream.

Parameters:

input - To read from.

Returns:

A new blob instance.

Throws:

IOException - If that fails.
