         java.util.Map<java.lang.String,AttachmentValue> attachments,
         Timestamp timestamp)

Description copied from class: MutableAggregation

Put a new value into the MutableAggregation.

Specified by:

add in class 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

void combine(MutableAggregation other,
             double fraction)

Description copied from class: MutableAggregation

Specified by:

combine in class MutableAggregation

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].
