WKID question of OGCGeometry.fromText() and OGCGeometry.fromBinary()

[yiranwang]

public static OGCGeometry fromText(String text) {
OperatorImportFromWkt op = (OperatorImportFromWkt)OperatorFactoryLocal.getInstance().getOperator(Type.ImportFromWkt);
OGCStructure ogcStructure = op.executeOGC(0, text, (ProgressTracker)null);
return createFromOGCStructure(ogcStructure, SpatialReference.create(4326));
}
For this function (same as fromBinary), it will output OGCGeometry using the WKID 4326 directly. If the input text has some information of SRID which is not 4326, what should we do? Or current api for all the relations (such as st_contains, st_intersects etc.) is just suited for 4326 spatial reference system. In the function fromGeoJson or fromJson, it will parse the WKID from the Json input and set the SpatialReference. Here, I have a question: if the SRID is not 4326, when we do the relation query for these geometries, do we use the spatial reference system in the input JSON, or we change the spatial reference system to the 4326? Thank you!

Currently, ImportFromWkt doesn't import spatial references from text. We can add that functionality if you need it.
I don't understand what you mean when you say that relational operations are suited only for 4326. Can you explain it more?

Thank you so much! Yes, I think for the functions fromText or fromBinary, it's better to have the part to import the spatial reference. If there is no information of WKID or SRID in the WKT or WKB, we could use the 4326 as default one. For the second question, for example, I run this:
containsOperator.execute(leftGeometry.getEsriGeometry(), rightGeometry.getEsriGeometry(), leftGeometry.getEsriSpatialReference(), null);
In public boolean execute(Geometry inputGeom1, Geometry inputGeom2, SpatialReference sr, ProgressTracker progressTracker) {
return RelationalOperations.relate(inputGeom1, inputGeom2, sr, 1, progressTracker);
}
If the WKID of sr is not 4326, could we guarantee the correctness of the containsOperator.execute(...)?

Yes, the relational operators work correctly no matter which spatial reference is used.
