Description

Interface Summary

BindingModel	Extends ReadOnlyBindingModel and provides update methods.
ColumnModel	Interface for information about columns.
DataModel	This is the data interface for JClass DataSource.
DataModelListener	Objects interested in receiving DataModelEvents must implement this interface.
DataTableAbstractionLayer	This interface is only of interest to those who wish to implement their own data source using some other implementation.
DataTableModel	This is the interface for data storage for the JClass DataSource datamodel.
IdeDataTableModel	An interface which abstracts common IDE methods.
IdeMetaDataModel	An interface which abstracts common ide methods.
MetaDataModel	This is the interface for objects that hold the meta-data for data tables.
ProviderModel	Classes implementing this interface can be specified as providers of data for MetaData levels.
ReadOnlyBindingListener	Passive listeners -- objects interested in receiving only read-only DataModelEvents should implement this interface.
ReadOnlyBindingModel	This interface provides a single-level, 2-dimensional view of a set of data.
StoreModel	Provides storage and retrieval for DataTableData.
TreeIteratorModel	This is the interface for an iterator which will traverse the list of children for this this node.
VirtualColumnModel	This is the interface for derived columns which can be added to DataSource.

Class Summary

BaseColumn	An implementation of ColumnModel.
BaseDataTable	This class provides a default implementation of DataTableModel and DataTableAbstractionLayer interfaces.
BaseMetaData	Base implementation of MetaDataModel.
BaseVirtualColumn	Adds columns to rows which are not retrieved from the data source.
Binding	Extends ReadOnlyBinding and provides update methods.
DataModelAdapter	DataModelListener adapter for DataModelEvent.
DataModelEvent	DataModelEvent describes changes to the data source.
DataSourceTreeModel	This class extends the swing DefaultTreeModel to provide methods required by JClass DataSource.
DataSourceTreeNode	This class extends the swing DefaultMutableTreeNode to provide methods required by JClass DataSource.
ErrorDialog	This is a class for displaying DataSource errors in a popup dialog.
ForwardTreeIterator	Iterates over the siblings of a tree in the Forward direction; extends TreeIterator.
IdeDataTable	This class extends BaseDataTable to provide functionality common to IDE implementations.
IdeMetaData	Exploits commonality betwee ides.
JCVersion	In JClass, each package has a JCVersion class.
LocaleBundle	Locale specific tag-message pairs used in DataSource to provide internationalization.
LoginDialog	A user login dialog is used to prompt user entering login information.
ReadOnlyBinding	This class provides a single-level, 2-dimensional view of a set of data.
ReverseTreeIterator	Iterates over the siblings of a tree in the Reverse direction; extends TreeIterator.
Store	Provides storage and retrieval for DataTableData.
TreeData	An implementation of DataModel.
TreeIterator	Iterates over the siblings of a tree; extends TreeIteratorModel.

Exception Summary

DataModelException

Any exceptions from this data model will be wrapped in this DataModelException.

Package com.klg.jclass.datasource Description

Contains the core classes for JClass Datasource. JClass DataSource allows you to access multiple tables in multiple databases by expressing a hierarchy of queries. JClass DataSource represents this hierarchy as a tree so your components can easily navigate the meta data and bind to a particular table and column. It may be used in conjunction with any data bound component, such as Quest's JClass LiveTable and JClass Field, and it can be tied to a grid or multiple tables to display hierarchical data.
