EventMetricType

public class EventMetricType<ExtraKeysEnum, ExtraObject> where ExtraKeysEnum : EventExtraKey, ExtraObject : EventExtras

This implements the developer facing API for recording events.

Instances of this class type are automatically generated by the parsers at built time, allowing developers to record events that were previously registered in the metrics.yaml file.

The Events API only exposes the EventMetricType.record(extra:) method, which takes care of validating the input data and making sure that limits are enforced.

  • The public constructor used by automatically generated metrics.

    Declaration

    Swift

    public init(_ meta: CommonMetricData, _ allowedExtraKeys: [String]? = nil)

  • Record an event by using the information provided by the instance of this class.

    Declaration

    Swift

    @available(*, deprecated, message: "Specify types for your event extras. See the reference for details.")
public func record(extra: [ExtraKeysEnum : String])

    Parameters

    extra

    (optional) A map of extra keys. Keys are identiifers and mapped to their registered name, values need to be strings. This is used for events where additional richer context is needed. The maximum length for values is defined by MAX_LENGTH_EXTRA_KEY_VALUE.

  • Undocumented

    Declaration

    Swift

    public func record(_ properties: ExtraObject? = nil)

  • Returns the stored value for testing purposes only. This function will attempt to await the last task (if any) writing to the the metric’s storage engine before returning a value.

    Declaration

    Swift

    public func testGetValue(_ pingName: String? = nil) -> [RecordedEvent]?

    Parameters

    pingName

    represents the name of the ping to retrieve the metric for. Defaults to the first value in sendInPings.

    Return Value

    value of the stored metric or nil if nothing was recorded.

  • Returns the number of errors recorded for the given metric.

    Declaration

    Swift

    public func testGetNumRecordedErrors(_ errorType: ErrorType, pingName: String? = nil) -> Int32

    Parameters

    errorType

    The type of error recorded.
    pingName

    represents the name of the ping to retrieve the metric for. Defaults to the first value in sendInPings.

    Return Value

    The number of errors recorded for the metric for the given error type.
