build
Description copied from interface:DoubleCounterBuilder
Builds and returns a Counter instrument with the configuration.- Specified by:
build
in interfaceDoubleCounterBuilder
- Returns:
- The Counter instrument.
-
buildWithCallback
Description copied from interface:DoubleCounterBuilder
Builds an Asynchronous Counter instrument with the given callback.The callback will be called when the instrument is being observed.
Callbacks are expected to abide by the following restrictions:
- Run in a finite amount of time.
- Safe to call repeatedly, across multiple threads.
- Specified by:
buildWithCallback
in interfaceDoubleCounterBuilder
- Parameters:
callback
- A callback which observes measurements when invoked.
-
buildObserver
Description copied from interface:DoubleCounterBuilder
Build an observer for this instrument to observe values from aBatchCallback
.This observer MUST be registered when creating a
batchCallback
, which records to it. Values observed outside registered callbacks are ignored.- Specified by:
buildObserver
in interfaceDoubleCounterBuilder
- Returns:
- an observable measurement that batch callbacks use to observe values.
