IgnoringGC
A measurer that discards measurements during which it detects GC cycles.
A measurer that discards measurements during which it detects GC cycles.
Assume that M measurements are requested.
To prevent looping forever, after the number of measurement failed due to GC
exceeds the number of successful measurements by more than M, the subsequent
measurements are accepted regardless of whether GC cycles occur.

Does some final cleanup after execution of all benchmarks in a performance test.
Does some final cleanup after execution of all benchmarks in a performance test.
This method is invoked in the PerformanceTest executeTests method
just after execution of all benchmarks.
Most measurers do not need to do any side effects in beforeExecution, so the default implementation just does nothing.

Does some side effects before execution of all benchmarks in a performance test.
Does some side effects before execution of all benchmarks in a performance test.
This method is invoked in the PerformanceTest executeTests method
just before execution of any benchmarks.
Most measurers do not need add additional context keys in prepareContext, so the default implementation just does nothing.

Modifies the initial test context.
Modifies the initial test context.
This method is invoked before the PerformanceTest object's ctor is invoked.
The key-value pairs that the org.scalameter.Measurer adds to
the org.scalameter.Context in this method are visible to all
the test snippets within the PerformanceTest class.
Most measurers do not need to add any specific keys,
so the default implementation just returns the context.

Returns the value used for the benchmark at iteration.
May optionally call regen to obtain a new value for the benchmark.
Returns the value used for the benchmark at iteration.
May optionally call regen to obtain a new value for the benchmark.
By default, the value v is always returned and the value for the
benchmark is never regenerated.
