示例1: it
it("should clear typed arrays to typed arrays", () => {
for (const typ of [Float32Array, Float64Array, Int32Array]) {
const r = new ColumnDataSource({data: {foo: [10, 20], bar: new typ([1,2])}})
r.clear()
expect(r.data).to.be.deep.equal({foo: [], bar: new typ([])})
}
})示例2: it
it("should update its indices when its source streams new data", () => {
const cds = new ColumnDataSource({data: {x: [], y: []}})
const new_data = {x: [1], y: [1]}
const view = new CDSView({source: cds})
expect(view.indices).to.be.deep.equal([])
cds.stream(new_data)
expect(view.indices).to.be.deep.equal([0])
