方法詳細資訊

registerCommandHandler

()方法
public static function registerCommandHandler(commandName:String, handler:Function):Boolean

語言版本: ActionScript 3.0
執行階段版本: Flash Player 11.4, AIR 3.4

註冊函數,以便經由通訊端發出命令加以呼叫

如果註冊成功,則會傳回 true。如果註冊失敗,表示已經有處理常式註冊所使用的命令 (或者命令名稱以 '.' 開頭,以保留供播放程式內部使用)。在註冊其他處理常式之前,請使用 unregisterCommandHandler 將已註冊的處理常式取消註冊。

處理常式函數的傳回值是以命令的結果 (tlm-response.result) 形式傳回。處理常式函數若要傳送錯誤回應,則會擲回 Error。在這種情況下,Error.messageError.id 會個別以 tlm-response.tlm-error.messagetlm-response.tlm-error.code 來傳送 (tlm-response.resulttlm-response.tlm-error.data 是以 null 傳送)。

參數

commandName:String — 指定唯一名稱的字串 (經由通訊端的命令應將這個字串指定為方法名稱)。原則是遵循反轉 DNS 標記法,以便有助於避免發生命名空間衝突。此外,保留以 . 為開頭的名稱,做為原生之用。
 
handler:Function — 遙測使用如 functionId 引數中所指定的方法名稱,經由通訊端接收命令時要呼叫的函數。處理常式應只接受 Array 類型的一個引數 (如遙測通訊協定中的 tlm-method.params 所定義),該引數必須與方法名稱一同由遙測伺服器傳送。

傳回值
Boolean

sendMetric

()方法 
public static function sendMetric(metric:String, value:*):void

語言版本: ActionScript 3.0
執行階段版本: Flash Player 11.4, AIR 3.4

要求遙測中的自訂公制。公制名稱和物件會以每個遙測通訊協定格式來傳送。

自訂公制命名空間的原則是,遵循反轉 DNS 標記法,以便有助於避免發生命名空間衝突。

參數

metric:String — 公制名稱
 
value:* — 任何包含公制詳細資料的基本值/物件


擲回值
ArgumentError — 公制使用保留的命名空間,如 Flash 原生命名空間 (例如,公制名稱以「.」開頭)

sendSpanMetric

()方法 
public static function sendSpanMetric(metric:String, startSpanMarker:Number, value:* = null):void

語言版本: ActionScript 3.0
執行階段版本: Flash Player 11.4, AIR 3.4

要求遙測中的自訂範圍公制

使用 Telemetry.spanMarker 可以取得位於要剖析之函數開頭的標記,並使用標記在函數結尾呼叫 Telemetry.sendSpanMetric。遙測會依照每個遙測通訊協定,傳送名稱、函數開始標記與持續時間,以及選擇性值。

自訂公制命名空間的原則是,遵循反轉 DNS 標記法,以便有助於避免發生命名空間衝突。

若持續時間的範圍公制少於指定的臨界值 (可使用遙測通訊協定從遙測伺服器加以控制),將遭到遙測忽略 (不會傳送給遙測伺服器)。

參數

metric:String — 公制名稱
 
startSpanMarker:Number — 開始標記。
 
value:* (default = null) — 選擇性參數。任何要與名稱、標記和持續時間一起傳送的基本值/物件


擲回值
ArgumentError — 公制使用保留的命名空間,如 Flash 原生命名空間 (例如,公制名稱以 '.' 開頭)
