org.debellor.base.TimeWindows
public class TimeWindows
- extends Cell
Treats input samples as elements of a time series
and generates time windows composed of a fixed number of
consecutive input samples, with every possible offset from the
beginning of the input stream.
Offsets are scanned in increasing order.
Output samples have the type of a DataVector
,
whose elements are the whole input samples
(actually the data field of input samples).
Decisions of output samples are null
.

TimeWindows
public TimeWindows()
onOpen
protected Sample.SampleType onOpen()
throws java.lang.Exception
- Description copied from class:
Cell
- Called by
Cell.open()
. Performs the actual opening of
communication session,
while open
checks only against access violation and handles exceptions.
Must be overridden in subclasses if open
is to be used.
Overriders may assume that the cell is in Cell.State.CLOSED
state.
- Overrides:
onOpen
in class Cell
- Throws:
java.lang.Exception
onNext
protected Sample onNext()
throws java.lang.Exception
- Description copied from class:
Cell
- Called by
Cell.Stream.next()
. Performs the actual generation of the next output sample,
while Stream.next()
checks only against access violation and handles exceptions.
Must be overridden in the subclass if next
is to be used, i.e.
if the subclass should generate some output data.
Overriders may assume that the cell is in Cell.State.OPEN
state.
- Overrides:
onNext
in class Cell
- Throws:
java.lang.Exception
onClose
protected void onClose()
throws java.lang.Exception
- Description copied from class:
Cell
- Called by
Cell.Stream.close()
. Performs the actual closing of
communication session,
while close
checks only against access violation and handles exceptions.
Must be overridden in subclasses if close
is to be used.
Usually the overrider will use onClose to release resources,
to let them be garbage-collected.
Overriders may assume that the cell is in Cell.State.OPEN
state.
- Overrides:
onClose
in class Cell
- Throws:
java.lang.Exception
