Jody did a nice work of putting global configuration in a central place
(org.geotools.factory.GeoTools). I continued on his track. Now we have:
* System properties String defined in org.geotools.factory.GeoTools,
instead of various places in Geotools code base. For now:
- CRS_AUTHORITY_EXTRA_DIRECTORY
- EPSG_DATA_SOURCE
- FORCE_LONGITUDE_FIRST_AXIS_ORDER
* A Hints.putSystemDefault(Key,Object) method added. Now the following
codes should have the same effect:
System.setProperty(GeoTools.FORCE_LONGITUDE_FIRST_AXIS_ORDER, "true");
or
Hints.putSystemDefault(Hints.FORCE_LONGITUDE_FIRST_AXIS_ORDER, Boolean.TRUE);
The former has the following advantages:
* Can be specified on the command line.
The later has the following advantages:
* No security constrains (or is it an inconvenient?)
* Any hint defined in org.geotools.factory.Hints can be set as a
system default, instead of only a few system property strings.
Currents factories in gt2-main ignore hints. I don't know if we plan to use them
in the future. But if there is such a possibility, it may be worth to make the
following classes extend org.geotools.factory.AbstractFactory:
org/geotools/data/FeatureLockFactory.java
org/geotools/data/AbstractDataStoreFactory.java
org/geotools/styling/AbstractStyleFactory.java
The cost is an initially empty HashMap instance inherited by all those
factories. Should I make such change (and add a Foo(Hints) constructor)?
