Uses of Package
com.sas.iquery.metadata.expr

Packages that use com.sas.iquery.metadata.expr

com.sas.iquery.dataservices	Provides utility classes and methods that are used to read information maps and retrieve filter values.
com.sas.iquery.metadata.business	The main package that provides modeling for SAS Query Services's two business models (information maps and data selections), which provide a logical layer of metadata modeling above the physical layer model.
com.sas.iquery.metadata.business.step.olap	Provides a set of modeled "step" operations that can be applied, in a particular order, to OLAP data items and business queries in order to filter the data that gets returned when business queries are executed.
com.sas.iquery.metadata.expr	Provides classes that are used to model expressions, which are used to compose data items and filters.
com.sas.iquery.metadata.expr.olap	Provides classes used to define OLAP expressions usable within a business model for defining portions of an OLAP business query.
com.sas.iquery.metadata.expr.relational	Provides classes that are used to model relational database expressions which are typically used when defining the expression portion of filters.
com.sas.iquery.metadata.serverprop	Provides specific information (via a ServerProperties object) about the capabilities of the server, such as operators and recognized functions.
com.sas.iquery.util	Utility classes that SAS Query Services makes available for use with its models.
