Constructor Detail

DataBuffer

public DataBuffer(List<String> attributes)

Creates an empty buffer with an initial list of attributes to watch for.

Parameters:

attributes - The attributes to watch for, including * expansions.

Method Detail

record

public void record(Measurement measurement)

Records the measurement and notices which attributes were present. In case of the warmUp phase, we record the attributes with _warmUp suffix to later separate the two phases. The list of attributes with the _warmUp extension is created in C3ChartHelper.

Parameters:

measurement - The measurement to be recorded.

replay

public void replay(Consumer<Measurement> consumer,
                   boolean fillNulls)

Replays the stored measurements to the given consumer. Makes sure that each measurement contains all the attributes (it adds them with null values if some were missing).

Parameters:

consumer - Consumer of the records. The records are replayed in the original order.

fillNulls - If true, the missing attributes will be added and their value set to null.

replay

public void replay(Consumer<Measurement> consumer)

Replays the stored measurements to the given consumer. Makes sure that each measurement contains all the attributes (it adds them with null values if some were missing).

Parameters:

consumer - Consumer of the records. The records are replayed in the original order.

getAttributes

public List<String> getAttributes()

Get the list of all attributes noticed during recording.

Returns:

The list of all attributes noticed during recording.
