class | DataPoint |
Public Member Functions | |
void | add_level (int index, double level) |
Adds a particular level value associated with a given collector to the frame data. | |
void | add_start (int index, double time) |
Adds a 'start collector' data point to the frame data. | |
void | add_stop (int index, double time) |
Adds a 'stop collector' data point to the frame data. | |
void | clear () |
Removes all the data points from the frame data, in preparation for building up a new frame's worth. | |
double | get_end () const |
Returns the time of the last data point in the frame data. | |
double | get_level (int n) const |
Returns the height of the nth level value. | |
int | get_level_collector (int n) const |
Returns the index of the collector associated with the nth level value. | |
double | get_net_time () const |
Returns the total time elapsed for the frame. | |
int | get_num_events () const |
Returns the number of individual events stored in the FrameData. | |
int | get_num_levels () const |
Returns the number of individual level values stored in the FrameData. | |
double | get_start () const |
Returns the time of the first data point in the frame data. | |
double | get_time (int n) const |
Returns the timestamp of the nth event, in seconds elapsed since some undefined epoch (which is guaranteed to be shared among all events returned from a given client). | |
int | get_time_collector (int n) const |
Returns the index of the collector associated with the nth event. | |
bool | is_empty () const |
Returns true if the FrameData has no time or level data. | |
bool | is_level_empty () const |
Returns true if there are no levels indicated in the frame data, false otherwise. | |
bool | is_start (int n) const |
Returns true if the nth event represents a start event, or false if it represents a stop event. | |
bool | is_time_empty () const |
Returns true if there are no time events in the frame data, false otherwise. | |
void | read_datagram (DatagramIterator &source, PStatClientVersion *version) |
Extracts the FrameData definition from the datagram. | |
void | sort_time () |
Ensures the frame data is in monotonically increasing order by time. | |
void | swap (PStatFrameData &other) |
Exchanges the data in this object with the data in the other. | |
bool | write_datagram (Datagram &destination, PStatClient *client) const |
Writes the definition of the FrameData to the datagram. |
Contains the raw timing and level data for a single frame.
This is a sequence of start/stop events, as well as a table of level values, associated with a number of collectors within a single frame.
