org.vfny.geoserver.global.Data
| Data | | public class Data extends GlobalLayerSupertype (Code) | | This class stores all the information that a catalog would (and CatalogConfig
used to).
All public methods besides constructors and stuff used for dependency injection
setters is synchronized to avoid response failures during the Geoserver reconfiguration
process (basically, each time you apply a new configuration set on the user interface).
A quick benchar did not show significant scalability loss. If one is to be encountered,
a more complex Reader/Write synchronization will be used, based on the java 5 concurrency
classes or their backport for java 1.4

| Method Summary | |
| public File | getBaseDir()
Returns the baseDir for use with relative paths. | | public synchronized int | getConnectionCount()
The number of connections currently held.
We will need to modify DataStore to provide access to the current count
of its connection pool (if appropriate). | | public synchronized CoverageInfo | getCoverageInfo(String name)

DataStore equals One "Connection".
This is a good compromize since I just want to indicate the amount of
resources currently tied up by GeoServer.

wondered what it was doing - this is it.

| getFeatureTypeInfo | | public synchronized FeatureTypeInfo getFeatureTypeInfo(String typename, String uri)(Code) | | Gets a FeatureTypeInfo from a local type name (ie unprefixed), and a uri.
This method is slow, use getFeatureType(String typeName), where possible.
For not he only user should be TransactionFeatureHandler.

| registerDataStore | | public synchronized void registerDataStore(DataStore dataStore) throws IOException(Code) | | Register a DataStore with this Catalog.
This is part of the public CatalogAPI, the fact that we don't want to
support it here may be gounds for it's removal.
GeoSever and the global package would really like to have complete
control over the DataStores in use by the application. It recognize that
this may not always be possible. As GeoServer is extend with additional
Modules (such as config) that wish to locate and talk to DataStores
independently of GeoServer the best we can do is ask them to register
with the this Catalog in global.
This reveals what may be a deisgn flaw in GeoTools2 DataStore. We have
know way of knowing if the dataStore has already been placed into our
care as DataStores are not good at identifying themselves. To complicate
matters most keep a static connectionPool around in their GDSFactory - it
could be that the Factories are supposed to be smart enough to prevent
duplication.
Parameters:
dataStore -
throws:
IOException -

Returns a map of Exception by prefix:typeName. If by some marvel the we
could connect to a FeatureSource we will record Boolean.TRUE.

| toDTO | | public synchronized Object toDTO()(Code) | | toDTO purpose.
This method is package visible only, and returns a reference to the
GeoServerDTO. This method is unsafe, and should only be used with extreme
caution.
