Optional aInstancePtr: objectA run time mechanism for interface discovery.
NS_OK if the interface is supported by the associated instance, NS_NOINTERFACE if it is not.
aInstancePtr must not be null.
[in] A requested interface IID
[out] A pointer to an interface pointer to receive the result.
Test-only API
Get a list of currently stored events for this event metric.
This function will attempt to await the last parent-process task (if any) writing to the the metric's storage engine before returning a value. This function will not wait for data from child processes.
This doesn't clear the stored value. Parent process only. Panics in child processes.
value of the stored metric, or undefined if there is no value.
The data is an array of objects:
[
{
timestamp: Integer,
category: String,
name: String,
extra: {
String: String
...
}
},
...
]
The difference between event timestamps is in milliseconds See https://mozilla.github.io/glean/book/user/metrics/event.html for further details. Due to limitations of numbers in JavaScript, the timestamp will only be accurate up until 2^53. (This is probably not an issue with the current clock implementation. Probably.)
The (optional) name of the ping to retrieve the metric
for. Defaults to the first value in send_in_pings.
Generated using TypeDoc
Increases the reference count for this interface. The associated instance will not be deleted unless the reference count is returned to zero.
Returns
The resulting reference count.
