示例1: __call__
# 需要导入模块: from osgeo import gdal [as 别名]
# 或者: from osgeo.gdal import PushErrorHandler [as 别名]
def __call__(self, *args, **kwargs):
errs, res = None, None
def error_handler(err_level, err_no, err_msg):
nonlocal errs
if err_level >= gdal.CE_Failure:
errs = err_no, err_msg
gdal.PushErrorHandler(error_handler)
try:
res = self._fn(*args, **kwargs)
except Exception as e:
if errs is None:
# This is not a gdal error, this might be a swig error or something else
raise
else:
# This is a gdal error, and `gdal.GetUseExceptions()` is True
# Read problems from the `errs` variable, the details stored in this exception
# are not reliable.
pass
finally:

if errs:
return False, errs
if self._none_is_error and res is None:
return False, (0, str(gdal.GetLastErrorMsg()).strip('\n'))
