getArity

public int getArity()

Description copied from interface: BaseRow

Get the number of fields in the BaseRow.

Specified by:

getArity in interface BaseRow

Returns:

The number of fields in the BaseRow.

getHeader

public byte getHeader()

Description copied from interface: BaseRow

The header represents the type of this Row. Now just used in streaming. Now there are two message: ACCUMULATE_MSG and RETRACT_MSG.

Specified by:

getHeader in interface BaseRow

setHeader

public void setHeader(byte header)

Description copied from interface: BaseRow

Set the byte header.

Specified by:

setHeader in interface BaseRow

isNullAt

public boolean isNullAt(int i)

Description copied from interface: TypeGetterSetters

Because the specific row implementation such as BinaryRow uses the binary format. We must first determine if it is null, and then make a specific get.

Specified by:

isNullAt in interface TypeGetterSetters

Returns:

true if this field is null.
