Method Details

setBlocking

public void setBlocking(boolean blocking)

Description copied from interface: SkipableTableReader

As implemented, blocking means sleep and retry.

Specified by:

setBlocking in interface SkipableTableReader

getSize

public long getSize()
             throws IOException

Specified by:

getSize in interface SkipableTableReader

Throws:

IOException

skipToRecord

public void skipToRecord(long recordNo)
                  throws IOException

Specified by:

skipToRecord in interface SkipableTableReader

Throws:

IOException

close

public void close()
           throws IOException

Description copied from interface: TableReader

Close the input source for this TableReader.

Specified by:

close in interface TableReader

Throws:

IOException

readData

protected void readData(int minAmount,
 ByteBuffer dataBuffer)
                 throws IOException

If this reader is not in blocking mode, read up to dataBuffer.remaining() bytes and return.

If blocking, read at least minAmount bytes from the input channel. Sleep 1 second between attempts to get more data up to minAmount. Do not acknowledge EOF, hoping more data will appear.

Specified by:

readData in class AbstractBinaryStoreReader

Parameters:

minAmount - don't return without this many bytes (if blocking)

dataBuffer - put the bytes in ths buffer.

Throws:

IOException
