ObjectArrayRow

public ObjectArrayRow(int arity)

方法详细资料

getArity

public int getArity()

从接口复制的说明: BaseRow

Get the number of fields in the BaseRow.

指定者:

getArity 在接口中 BaseRow

返回:

The number of fields in the BaseRow.

getHeader

public byte getHeader()

从接口复制的说明: BaseRow

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

指定者:

getHeader 在接口中 BaseRow

setHeader

public void setHeader(byte header)

从接口复制的说明: BaseRow

Set the byte header.

指定者:

setHeader 在接口中 BaseRow

isNullAt

public boolean isNullAt(int ordinal)

从接口复制的说明: 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.

指定者:

isNullAt 在接口中 TypeGetterSetters

返回:

true if this field is null.

setNullAt

public void setNullAt(int ordinal)

从接口复制的说明: TypeGetterSetters

Set null to this field.

指定者:

setNullAt 在接口中 TypeGetterSetters

setDecimal

public void setDecimal(int i,
                       Decimal value,
                       int precision)

从接口复制的说明: TypeGetterSetters

Set the decimal column value.

Note: Precision is compact: can call setNullAt when decimal is null. Precision is not compact: can not call setNullAt when decimal is null, must call setDecimal(i, null, precision) because we need update var-length-part.

指定者:

setDecimal 在接口中 TypeGetterSetters

setTimestamp

public void setTimestamp(int ordinal,
                         SqlTimestamp value,
                         int precision)

从接口复制的说明: TypeGetterSetters

Set Timestamp value.

Note: If precision is compact: can call setNullAt when SqlTimestamp value is null. Otherwise: can not call setNullAt when SqlTimestamp value is null, must call setTimestamp(ordinal, null, precision) because we need to update var-length-part.

指定者:

setTimestamp 在接口中 TypeGetterSetters

getString

public BinaryString getString(int ordinal)

从接口复制的说明: TypeGetterSetters

Get string value, internal format is BinaryString.

指定者:

getString 在接口中 TypeGetterSetters

getBinary

public byte[] getBinary(int ordinal)

从接口复制的说明: TypeGetterSetters

Get binary value, internal format is byte[].

指定者:

getBinary 在接口中 TypeGetterSetters

getArray

public BaseArray getArray(int ordinal)

从接口复制的说明: TypeGetterSetters

Get array value, internal format is BaseArray.

指定者:

getArray 在接口中 TypeGetterSetters

getMap

public BaseMap getMap(int ordinal)

从接口复制的说明: TypeGetterSetters

Get map value, internal format is BaseMap.

指定者:

getMap 在接口中 TypeGetterSetters

getDecimal

public Decimal getDecimal(int ordinal,
                          int precision,
                          int scale)

从接口复制的说明: TypeGetterSetters

Get decimal value, internal format is Decimal.

指定者:

getDecimal 在接口中 TypeGetterSetters

getTimestamp

                                 int precision)

从接口复制的说明: TypeGetterSetters

Get Timestamp value, internal format is SqlTimestamp.

指定者:

getTimestamp 在接口中 TypeGetterSetters

getGeneric

public <T> BinaryGeneric<T> getGeneric(int ordinal)

从接口复制的说明: TypeGetterSetters

Get generic value, internal format is BinaryGeneric.

指定者:
