|
|
!! Module Vector_class |
| 3 |
|
|
!! Fortran 95 Vector class module. Similar to java.util vector class. |
| 4 |
|
|
!! |
| 5 |
|
|
!! The Vector class implements a growable array of objects. Like an array, |
| 6 |
|
|
!! it contains components that can be accessed using an integer index. However, |
| 7 |
|
|
!! the size of a Vector can grow as needed to accommodate |
| 8 |
|
|
!! adding and removing items after the Vector has been created. |
| 9 |
|
|
!! Each vector tries to optimize storage management by maintaining a capacity and a |
| 10 |
|
|
!! capacityIncrement. The capacity is always at least as large as the vector size; |
| 11 |
|
|
!! it is usually larger because as components are added to the vector, |
| 12 |
|
|
!! the vector's storage increases in chunks the size of capacityIncrement. |
| 13 |
|
|
!! An application can increase the capacity of a vector before inserting a large number |
| 14 |
|
|
!! of components; this reduces the amount of incremental reallocation. |
