## Methods

| Method | Description |
| --- | --- |
| [alg(T el, int index)](#alg-T-int-) | Processes an object in the list. |
| [postAlg(T el, int index)](#postAlg-T-int-) | Called after processing of an object. |
| [preAlg(T el, int index)](#preAlg-T-int-) | Called before processing of an object. |
### alg(T el, int index) {#alg-T-int-}
```
public abstract void alg(T el, int index)
