Method Details

add

abstract void add(double value,
 Map<String, AttachmentValue> attachments,
 Timestamp timestamp)

Put a new value into the MutableAggregation.

Parameters:

value - new value to be added to population

attachments - the contextual information on an Exemplar

timestamp - the timestamp when the value is recorded

combine

abstract void combine(MutableAggregation other,
 double fraction)

Combine the internal values of this MutableAggregation and value of the given MutableAggregation, with the given fraction. Then set the internal value of this MutableAggregation to the combined value.

Parameters:

other - the other MutableAggregation. The type of this and other MutableAggregation must match.

fraction - the fraction that the value in other MutableAggregation should contribute. Must be within [0.0, 1.0].
