Method Details

getProtocolVersion

public ProtocolVersion getProtocolVersion()

unmask

public boolean unmask()

add

public void add(ByteBuffer v)

public void add(ColumnData columnData,
 long nowInSec)

getValue

public ByteBuffer getValue(int index)

Return the value of the column with the specified index.

Parameters:

index - the column index

Returns:

the value of the column with the specified index

reset

public void reset(boolean deep)

Reset the row internal state.

If the reset is not a deep one only the index will be reset. If the reset is a deep one a new array will be created to store the column values. This allow to reduce object creation when it is not necessary.

Parameters:

deep - true if the reset must be a deep one.

getValues

public List<ByteBuffer> getValues()

Returns the column values as list.

This content of the list will be shared with the InputRow unless a deep reset has been done.

Returns:

the column values as list.
