com.devexperts.qd.DataIterator

Packages that use DataIterator

Package	Description
com.devexperts.qd	This package contains basic interfaces and other API elements of QD system which shall be sufficient for the client application programmer.
com.devexperts.qd.ng	This package contains next-generation interfaces for data and subscription exchange based on RecordCursor class.
com.devexperts.qd.qtp	This package contains interfaces with default implementations required to create and operate a connection using QTP.
com.devexperts.qd.util	This package contains utility classes which are used by QD, but which do not depend on QD and which do not constitute any separate module or subsystem.
