Package org.epics.pvdata.factory

This package implements the interfaces defined in org.epics.pvdata.pv.

It provides everything required for creating pvData. It provides the following factories:

FieldFactory

Creates introspection interfaces.

PVDataFactory

Creates data interfaces for all of the supported data types.

ConvertFactory

Converts between support data types.

Although pvDataFactory can provide the implementation for all supported data types, often it is desirable to provide other implementations. To make it easy to create alternate implementations a set of abstract and base classes are supplied.
