Method Detail

getTreeMap

public TreeMap<Interval,V> getTreeMap()

readForward

public TimeIterator<V> readForward(Interval interval,
                                   ExecutorContext context)

Description copied from interface: Variable

Read the given interval returning a forward time iterator from start to end. More specifically, return an iterator for all the samples whose interval overlaps or is contained by interval.

Specified by:

readForward in interface Variable<V>

Parameters:

interval - The interval to read

context - Evaluation context

Returns:

A TimeIterator reading the map forward for the given interval.

readBackward

public TimeIterator<V> readBackward(Interval interval,
                                    ExecutorContext context)

Description copied from interface: Variable

Read the given interval returning a reverse time iterator from the end to start. More specifically, return an iterator for all the samples whose interval overlaps or is contained by interval in reverse order.

Specified by:

readBackward in interface Variable<V>

Parameters:

interval - The interval to read

context - Evaluation context

Returns:

A TimeIterator reading the map backward for the given interval.

write

public void write(Sample<V> sample,
                  ExecutorContext context)

Description copied from interface: Variable

Write a sample into the variable.

Specified by:

write in interface Variable<V>

Parameters:

sample - The sample to store

context - Executor context
