Class FunctionUtil

Buffer the function with this number of milliseconds. When the function is called multiple times within the delay period only the last call will execute.

Create a combined function of an orignal and new function. The new function will be called before the original,

Example

export function playgroundTableOverride() {
    PlaygroundTable.prototype.render = FunctionUtil.createInterceptor(
        PlaygroundTable.prototype.render,
        function(this:PlaygroundTable) {
            this.el.classList.add("cls-added-by-override");
        }
    )
}
Copy

Will combine the given functions into one.

The newFn function will be called with the return value of origFn function + the parameters of origFn and function will return the value of newFn

Example

function test(a:number, b:string) : string {
    return b;
}

FunctionUtil.createSequence(test, function(r, a, b) {
    return r + "b";
})
Copy

Delay function execution

Execute on the next repaint

The onRepaint method tells the browser that you wish to perform an animation and requests that the browser calls a specified function to update an animation before the next repaint.
