the overall amount spent in API cycles, as returned by the system.
Returns 0 if the feature is not supported.
getCpuTimeInMegaCycles()
publicabstractlonggetCpuTimeInMegaCycles()
Measures the duration that the current request has spent so far processing
the request within the App Engine sandbox. Note that time spent in API
calls will not be added to this value.
The unit the duration is measured is Megacycles. If all instructions
were to be executed sequentially on a standard 1.2 GHz 64-bit x86 CPU,
1200 megacycles would equate to one second physical time elapsed.
Tests if the QuotaService can provide a certain kind of data at this
point in time. Depending on the underlying app server implementation and
what state it is in, a QuotaService might not always have access to all
categories of data. For example, the dev-appserver might not be able to
measure the megacycles of api calls. Trying to access that data would lead
to an IllegalStateException, which would then need to be handled. To make
it easier to prevent this, it is possible to ask the service if a
particular kind of data is supported.
