InputRow

public InputRow(int size,
                boolean collectTimestamps,
                boolean collectTTLs)

Method Detail

add

public void add(java.nio.ByteBuffer v)

add

public void add(Cell<?> c,
                int nowInSec)

getValue

public java.nio.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.

getTimestamp

public long getTimestamp(int index)

Return the timestamp of the column with the specified index.

Parameters:

index - the column index

Returns:

the timestamp of the column with the specified index

getTtl

public int getTtl(int index)

Return the ttl of the column with the specified index.

Parameters:

index - the column index

Returns:

the ttl of the column with the specified index

getValues

public java.util.List<java.nio.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.
