本文整理匯總了TypeScript中core/util/typed_array.concat函數的典型用法代碼示例。如果您正苦於以下問題：TypeScript concat函數的具體用法？TypeScript concat怎麽用？TypeScript concat使用的例子？那麽, 這裏精選的函數代碼示例或許可以為您提供幫助。
在下文中一共展示了concat函數的2個代碼示例，這些例子默認根據受歡迎程度排序。您可以為喜歡或者感覺有用的代碼點讚，您的評價將有助於係統推薦出更棒的TypeScript代碼示例。
示例1: it
it("should concat Float32 arrays", () => {
const a = new Float32Array([1, 2])
const b = new Float32Array([3, 4])
const r = typed_array.concat(a, b)
expect(r).to.be.instanceof(Float32Array)
expect(r).to.be.deep.equal(new Float32Array([1, 2, 3, 4]))
})示例2: stream_to_column
export function stream_to_column(col: Arrayable, new_col: Arrayable, rollover?: number): Arrayable {

if (rollover != null && result.length > rollover)
