Method Summary

Modifier and Type	Method and Description
default String	getColumnPartitionValue() For rows that are to be used with file managers that allow dynamic column partition selection, retrieve the column partition value.
RowSetter	getSetter(String name) Gets a setter for a column.
default <T> RowSetter<T>	getSetter(String name, Class<T> tClass) Gets a typed setter for a column.
default void	setColumnPartitionValue(String columnPartitionValue) For rows that are to be used with file managers that allow dynamic column partition selection, set the column partition value.
void	setFlags(Row.Flags flags)
long	size() Deprecated. Row.size() is somewhat ambiguously specified in the interface and its implementations. Some implementations keep track of all rows written. Others keep track of number of rows buffered. It seems safer to simply not allow the question to be asked.
void	writeRow() Writes out a new row (values set using setters).

Method Detail

getSetter

RowSetter getSetter(String name)

Gets a setter for a column.

Parameters:

name - column name

Returns:

setter for the column.

getSetter

default <T> RowSetter<T> getSetter(String name,
                                   Class<T> tClass)

Gets a typed setter for a column.

Parameters:

name - column name

tClass - the type for the typed RowSetter

Returns:

setter for the column.

writeRow

void writeRow()
       throws IOException

Writes out a new row (values set using setters).

Throws:

IOException - problem writing the row

size

@Deprecated
long size()

Deprecated. Row.size() is somewhat ambiguously specified in the interface and its implementations. Some implementations keep track of all rows written. Others keep track of number of rows buffered.

It seems safer to simply not allow the question to be asked.

Number of rows written out.

Returns:

number of rows written out.

setFlags

void setFlags(Row.Flags flags)

setColumnPartitionValue

default void setColumnPartitionValue(String columnPartitionValue)

For rows that are to be used with file managers that allow dynamic column partition selection, set the column partition value.

Parameters:

columnPartitionValue - the column partition value

getColumnPartitionValue

default String getColumnPartitionValue()

For rows that are to be used with file managers that allow dynamic column partition selection, retrieve the column partition value.

Returns:

the previously-set column partition value
