Method Detail

invoke

public abstract T invoke(T previous,
                         T newData)

A callback defining how two data elements on any two intervals should be combined when creating a new interval.

Parameters:

previous - The data existing on the original time interval.

newData - The data existing on the new time interval.

Returns:

A new instance of data representing the result of combining (merging) the previous data and the newData.
