CurveBS I/O processing flow Before introducing IO processing flow, we first describe the overall architecture, data organization and topology structure of CURVE. CurveBS uses the central the NEBDServer, which affects services in few seconds. CurveBS IO processing flow Overall process The flow of user's read and write request to curve: 1. The user initiates a request (fd=1 6. At last, the Client notifies the user that the request is completed.Chunkserver processing flow CopysetNode is essentially a wrapper around the RAFT algorithm. The Copyset module encapsulates

resolve された時の処理(onFulfilled) • promiseオブジェクトが reject された時の処理(onRejected) Figure 2. promise value flow まずは、 getURL で通信が成功して値が取得できた場合の処理を書いてみましょう。 この場合の 通信が成功した というのは、 resolveされたことにより promiseオブジェクトが すなわちメソッドチェーンが短いことはよいことです。 この例では説明のために長いメソッドチェーンを用います。 次のようなpromise chainを見てみましょう。 promise-then-catch-flow.js function taskA() { console.log("Task A"); } function taskB() { console.log("Task B"); then(finalTask); このようなpromise chainをつなげた場合、 それぞれの処理の流れは以下のように図で表 せます。 Figure 3. promise-then-catch-flow.jsの図 上記のコードでは then は第二引数(onRejected)を使っていないため、 以下のように読み 替えても問題ありません。 23 JavaScript Promiseの本

mixture. We can mix even more easily with glazing when we set our brush's flow to a lower setting. Subtly different than opacity, flow is transparency per dab instead of stroke, and so it gives us softer strokes blending mode will darken and interact with each base color differently. Then, using a brush with low flow (~0.30), we can pick the resulting colors and lay down more layers. Not only does this help you define three-dimensionality, it also gives quite a nice, painterly effect! Continue with a lower opacity and flow to create even smoother gradients. Make your edges as sharp or smooth as your subject matter and art
