Class Model<T>Abstract

the type of the model's items.

Example

As an example let's see the implementation of ArrayModel

export class ArrayModel<T> extends Model<T> {
   private a: Array<T>

  constructor(arr: Array<T>) {
       super();
       this.a = arr;
   }

   rowCount() {
       return this.a.length;
   }

   rowData(row: number) {
      return this.a[row];
   }

   setRowData(row: number, data: T) {
       this.a[row] = data;
       this.notifyRowDataChanged(row);
   }

   push(...values: T[]) {
       let size = this.a.length;
       Array.prototype.push.apply(this.a, values);
       this.notifyRowAdded(size, arguments.length);
   }

   remove(index: number, size: number) {
       let r = this.a.splice(index, size);
       this.notifyRowRemoved(index, size);
   }

   get length(): number {
       return this.a.length;
   }

   values(): IterableIterator<T> {
       return this.a.values();
   }

   entries(): IterableIterator<[number, T]> {
       return this.a.entries()
   }
}
