# TList.Sort

Sorts the pointers in the list.

## Declaration

Source position: classesh.inc line 343

`public procedure TList.Sort(`
`Compare: TListSortCompare`
`);`

## Description

Sort> sorts the pointers in the list. Two pointers are compared by passing them to the Compare function. The result of this function determines how the pointers will be sorted:

- If the result of this function is negative, the first pointer is assumed to be 'less' than the second and will be moved before the second in the list.
- If the function result is positive, the first pointer is assumed to be 'greater than' the second and will be moved after the second in the list.
- if the function result is zero, the pointers are assumed to be 'equal' and no moving will take place.

The sort is done using a quicksort algorithm.
