Method Detail

create

static MutableAggregation.MutableDistribution create(BucketBoundaries bucketBoundaries)

Construct a MutableDistribution.

Returns:

an empty MutableDistribution.

add

void add(double value,
         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

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.

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].
