org.vfny.geoserver.global
GeoServer Global Maintains the GeoServer applicaiton state (This is the Application).

Common state used by the GeoServer Servlets is maintained by this package.

Features:
  • Contains the actual server state - that is WMS reflects the state of the Web Map Server
  • These classes should be saved in the Web Container (rather than the current singletons)
  • Application set up is provided using Data Transfer Objects from the global.dto package. Both the initial loading the initial XML configuration files and the dynamic configuraiton systems are handled in this manner.
  • Data contains "real" GeoTools2 DataStores with JDBC connections (and implements the GeoTools2 Catalog Interface)

GeoServer State Diagram

We would like to bootstrap this process using the STRUTS plug-in interface and store the GeoServer application state in the Web Container. Currently this information is accessed by a singleton, and bootstraped by the first GeoServer servlet request (JG - I think ).

Java Source File NameTypeComment
ApplicationState.javaClass This class represents the state of the GeoServer appliaction.

ApplicationState used by the state.jsp tile as a single view on the state of the GeoServer application.

AttributeTypeInfo.javaClass AttributeTypeInfo represents AttributeTypeMetaData for GeoServer.
CloneLibraryTest.javaClass CloneLibraryTest purpose.
Config.javaClass The application configuratoin facade.
ConfigurationException.javaClass Thrown when there is an error in configuration.
CoverageDimension.javaClass Represents a CoverageDimension Attribute.
CoverageInfo.javaClass
CoverageInfoLabelComparator.javaClass
CoverageStoreInfo.javaClass This is the configuration iformation for one coverage Format.
Data.javaClass 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.

DataStoreInfo.javaClass This is the configuration iformation for one DataStore.
EqualsLibraryTest.javaClass EqualsLibraryTest purpose.
FeatureTypeInfo.javaClass Represents a FeatureTypeInfo, its user config and autodefined information.
FeatureTypeInfoTitleComparator.javaClass
GeoServer.javaClass
GeoserverDataDirectory.javaClass This class allows for abstracting the location of the Geoserver Data directory.
GeoServerFeatureLocking.javaClass GeoServer wrapper for backend Geotools2 DataStore.

Support FeatureSource decorator for FeatureTypeInfo that takes care of mapping the FeatureTypeInfo's FeatureSource with the schema and definition query configured for it.

Because GeoServer requires that attributes always be returned in the same order we need a way to smoothly inforce this.

GeoServerFeatureSource.javaClass GeoServer wrapper for backend Geotools2 DataStore.

Support FeatureSource decorator for FeatureTypeInfo that takes care of mapping the FeatureTypeInfo's FeatureSource with the schema and definition query configured for it.

Because GeoServer requires that attributes always be returned in the same order we need a way to smoothly inforce this.

GeoServerFeatureStore.javaClass GeoServer wrapper for backend Geotools2 DataStore.

Support FeatureSource decorator for FeatureTypeInfo that takes care of mapping the FeatureTypeInfo's FeatureSource with the schema and definition query configured for it.

Because GeoServer requires that attributes always be returned in the same order we need a way to smoothly inforce this.

GeoServerPlugIn.javaClass GeoServerPlugIn purpose.

Used to load the config into GeoServer.

GeoServerServletContextInitializer.javaClass Places a GeoServer module into the servlet context.
GeoServerVersioningFeatureLocking.javaClass
GeoServerVersioningFeatureSource.javaClass
GeoServerVersioningFeatureStore.javaClass
GeoValidator.javaClass GeoValidator purpose.
GlobalLayerSupertype.javaClass This class implements some library function for all the sub classes in this package.
LegendURL.javaClass This class represents legend icon parameters.
Log4JFormatter.javaClass Log4JFormatter looks like:
 [core FINE] A log message logged with level FINE from the "org.geotools.core"
 logger.
A formatter writting log message on a single line.
MapLayerInfo.javaClass
MetaDataLink.javaClass Represents a MetadataLink Attribute.
NameSpaceInfo.javaClass NameSpaceInfo purpose.
Service.javaClass Default configuration for services.
TemporaryFeatureTypeInfo.javaClass
UserContainer.javaClass Represents a User for GeoServer.

Used as a typesafe Session container.

WCS.javaClass WCS

Represents the GeoServer information required to configure an instance of the WCS Server.

WMS.javaClass WMS

Represents the GeoServer information required to configure an instance of the WMS Server.
