Dbase numeric parsing is really inefficient
-------------------------------------------
Key: GEOT-1231
URL: http://jira.codehaus.org/browse/GEOT-1231
Project: GeoTools
Issue Type: Task
Components: data shapefile
Affects Versions: 2.3.1
Reporter: Andrea Aime
Assigned To: Ian Wolfe Schneider
Fix For: 2.3.1, 2.4.M2
extractNumberString shows quite prominently in a profile made against a
shapefile with a hundred of integer fields.
This is because three reallocations of memory are performed in this tiny method.
At least for integers and number, it would be a lot better to have some custom
parsing that works directly against
the charbuffer. The code would not be complex (not nearly as complex as
double/float parsing).
