Interface Summary

Catalog	This interface defines the common interface to all catalogs.
CatalogDirectory	This defines the interface for a catalog directory, allowing catalogs to be organized in a hierarchy.
FieldDesc	This interface describes a catalog field, which may be an input field, such as a query parameter, or an output field, such as a table column description.
HTMLQueryResultHandler	This interface defines a method that classes can call when an HTTP server unexpectedly returns an HTML page, which normally contains an error message about a broken link, etc.
PlotableCatalog	Defines the interface for catalogs whose tabular query results can be plotted on an image.
QueryArgs	An interface representing the values of the arguments to a catalog query.
QueryResult	Represents the result of a catalog query.
QueryResultHandler	This defines the common interface for classes that can fetch and parse a QueryResult, given the URL.
SearchCondition	An interface representing a search condition for values in a given table column, or parameters to a catalog query.
TableQueryResult	This interface defines the methods required to access tabular query results.

Class Summary

AbstractCatalogDirectory	A generic, abstract base class for catalog directory implementations.
AbstractSearchCondition	An abstract base class for SearchConditions.
ArraySearchCondition	Represents a search condition with an array of possible values.
BasicQueryArgs	Represents the values of the arguments to a catalog query.
CatalogFactory	Used to manage access to a known list of catalogs.
FieldDescAdapter	This class provides a default implementation of the FieldDesc interface, used to describes a catalog field (column or query parameter).
FieldFormat	This utility class provides a method to scan specially formatted values from a string and return an object of the correct type.
MemoryCatalog	Used to manage tabular catalog data in memory, such as the result of a catalog query or the contents of a local catalog file.
RangeSearchCondition	Represents a search condition for a range of values.
RowCoordinates	Stores information about which columns in a table contain the coordinates for that row, and whether world coordinates or image coordinates are supported.
TablePlotSymbol	Represents the contents of a catalog table plot symbol definition.
TestCatalog	Used for testing.
TestTableQueryResult	Used for testing.
URLQueryResult	Represents a query result of some type pointed to by a URL.
ValueRange	Represents a range of values, given by minValue and maxValue, where minValue <= x <= maxValue.
ValueSearchCondition	Represents a search condition for values in a given table column, or parameters to a query or request.
