4 | MODULE: ZZVec |
---|
5 | |
---|
6 | SUMMARY: |
---|
7 | |
---|
8 | The class ZZVec implements vectors of fixed-length ZZ's. You can |
---|
9 | allocate a vector of ZZ's of a specified length, where the maximum |
---|
10 | size of each ZZ is also specified. The size is measured in terms |
---|
11 | of the number of zzigits. |
---|
12 | |
---|
13 | These parameters can be specified either with a constructor |
---|
14 | or with SetSize. It is an error to try to re-size a vector of non-zero length, |
---|
15 | or store a ZZ that doesn't fit. The space can be released with "kill", |
---|
16 | and then you are free to call SetSize again. |
---|
17 | |
---|
18 | If you want more flexible---but less efficient---vectors, use vec_ZZ. |
