Classes
		telemetry.web_perf.metrics.timeline_based_metric.TimelineBasedMetric(__builtin__.object) GPUTimelineMetric   class GPUTimelineMetric(telemetry.web_perf.metrics.timeline_based_metric.TimelineBasedMetric)     Computes GPU based metrics.     Method resolution order: GPUTimelineMetric telemetry.web_perf.metrics.timeline_based_metric.TimelineBasedMetric __builtin__.object Methods defined here: AddResults(self, model, _, interaction_records, results) __init__(self) Methods inherited from telemetry.web_perf.metrics.timeline_based_metric.TimelineBasedMetric: AddWholeTraceResults(self, model, results) Computes and adds metrics corresponding to the entire trace.   Override this method to compute results that correspond to the whole trace.   Args:   model: An instance of telemetry.timeline.model.TimelineModel.   results: An instance of page.PageTestResults. VerifyNonOverlappedRecords(self, interaction_records) This raises exceptions if interaction_records contain overlapped ranges. Data descriptors inherited from telemetry.web_perf.metrics.timeline_based_metric.TimelineBasedMetric: __dict__ dictionary for instance variables (if defined) __weakref__ list of weak references to the object (if defined)

Functions
		TimelineName(name, source_type, value_type) Constructs the standard name given in the timeline.   Args:   name: The name of the timeline, for example "total", or "render_compositor".   source_type: One of "cpu", "gpu" or None. None is only used for total times.   value_type: the type of value. For example "mean", "stddev"...etc.
