Modifier and Type | Method and Description |
---|---|
void |
aggregate(ByteBuffer buf,
int position)
Aggregates metric values into the given aggregate byte representation
Implementations of this method must read in the aggregate value from the buffer at the given position,
aggregate the next element of data and write the updated aggregate value back into the buffer.
|
void |
init(ByteBuffer buf,
int position)
Initializes the buffer location
Implementations of this method must initialize the byte buffer at the given position
Implementations must not change the position, limit or mark of the given buffer
This method must not exceed the number of bytes returned by
AggregatorFactory.getMaxIntermediateSize()
