Problem determing proper geometry type with ArcSDE 9.x
------------------------------------------------------
Key: GEOT-899
URL: http://jira.codehaus.org/browse/GEOT-899
Project: GeoTools
Issue Type: Bug
Components: data arcsde
Affects Versions: 2.2-RC3
Environment: ArcSDE 9.0 and 9.1
Reporter: Richard Gould
Assigned To: Gabriel Roldán
Fix For: 2.2
Attachments: arcsde.patch
In ArcSDE 9.x, the constants in "SeLayer" seem to have changed. This can cause
ArcSDEAdapter.getGeometryType() to return an incorrect geometry.
it seems that there are two ways to determine a layer's geometry type:
1) Check its type against the TYPE_* constants, and
2) If that fails, check the type against the various SE_*_TYPE_MASK constants
The problem in this instance is that the SeLayer's geometry type is "2", which
corresponds to both TYPE_LINE and SE_POINT_TYPE_MASK. The layer's true geometry
is Point, but since it matches against TYPE_LINE in case 1, the wrong geometry
type is returned.
With my limited understanding of ArcSDE and the java API it uses, I propose a
method to hopefully fix this:
1) Check if the major version of the instance is 9 or higher. If it isn't,
proceed exactly as before.
2) If the major version is 9 or higher, do not perform case 1 above. (ie do not
check the type value against the TYPE_* constants)
Attached is a patch that makes these adjustments to ArcSDEAdapter on 2.2.x.
