[efdb01a] | 16 | November 2015 - Leopold Haimberger (University of Vienna): |
---|
| 17 | - modified method listFiles to work with glob instead of listdir |
---|
| 18 | - added pattern search in method listFiles |
---|
| 19 | |
---|
| 20 | February 2018 - Anne Philipp (University of Vienna): |
---|
[64cf353] | 21 | - applied PEP8 style guide |
---|
| 22 | - added documentation |
---|
[efdb01a] | 23 | - optimisation of method listFiles since it didn't work correctly |
---|
| 24 | for sub directories |
---|
| 25 | - additional speed up of method listFiles |
