-<p>This document describes pvDatabaseCPP,
-which is a framework for implementing a network accessible database of smart memory resident
+<p><b>pvDatabase</b> is a framework for implementing a network accessible database of smart memory resident
 records. Network access is via pvAccess. The data in each record is a top level PVStructure as defined by
 pvData. The framework includes a complete implementation of ChannelProvider as defined by pvAccess.
 The framework can be extended in order to create record instances that implements services.
 The minimum that an extension must provide is a top level PVStructure and a process method.

+<p>In particular look at database, exampleLink, and helloPutGet.
 </p>

-<h3>database</h3>

-other functionality.</p>
-<dl>
-   <dt>exampleDatabase.cpp</dt>
-     <dd>
-      This shows how to create soft records of each pvData type.<br />
-      In addition shows how to create instances of the following two records.
-     </dd>
-   <dt>exampleHelloRecord.cpp</dt>
-     <dd>
-       This is a simple "hello world" that is intentended to be used via a channelPutGet request.

-   <dt>exampleHelloRPC.cpp</dt>
-     <dd>
-       This is a simple "hello world" that is intentended to be used via a channelRPC request.

-      This has code and examples to create a V3 IOC which also has a PVDatabase.
-     </dd>
-</dl>

-<dl>
-  <dt>exampleMonitorLinkRecord</dt>
-     <dd>
-      This creates a monitor link to another record.
-     </dd>
-  <dt>exampleGetLinkRecord</dt>
-     <dd>
-      This creates a get link to another record.
-     </dd>
-  <dt>examplePutLinkRecord</dt>
-     <dd>
-      This creates a put link to another record.
-     </dd>
-</dl>
-
-<h3>support</h3>
-<p>This creates records that have the following features:</p>
-<dl>
-   <dt>value</dt>
-   <dd>
-    Each record has a value field the is a numeric scalar field.
-    In addition each has the following fields:
-    alarm,timeStamp,control,scalarAlarm, and display.
-   </dd>
-   <dt>support</dt>
-   <dd>
-     Each record uses the control and scalarAlarm support provided by pvDatabaseCPP.
-   </dd>
-</dl>
-<p>
-It also creates records that can be used by clients to show example of the plugin support.
-</p>
-
-<h2>iocshell commands</h2>
-<p>Shell commands are made available via the standard DBD include mechanism
-provided by iocCore.
-The following provide EPICS V4 shell commands:</p>
-<pre>
-pvAccessCPP
-qsrv
-pvDatabaseCPP
-</pre>
-
-<p>pvDatabaseCPP provides the following iocshell command.</p>
-<dl>
-   <dt>registerChannelProviderLocal</dt>
-     <dd>Including <b>registerChannelProviderLocal.dbd</b> as a dbd file automatically starts provider local
-      and also creates the pvdbl shell command.
-     </dd>
-   <dt>pvdbl</dt>
-      <dd>Provides a list of all the pvRecords in database <b>master</b>
-      </dd>
-</dl>
-<p>In addition any code that implements a PVRecord must implement an ioc command.
-Look at the examples in <b>exampleCPP/support</b> to see how to implement shell commands.</p>

Andrew Johnson	a514ab7b51	Add missing removal instructions for destroy()	2021-03-15 12:12:15 -05:00
mrkraimer	dafc37b585	The following changes were made: 1) PVRecord now has two new methods: setAsLevel and setAsGroup. 2) The following special records are DEPRECATED: addRecord,processRecord,removeRecord, and traceRecord. They are replaced by pvdbcrAddRecord,pvdbcrProcessRecord,pvdbcrRemoveRecord, and pvdbcrTraceRecord. 3) A new convention is that all special records start with pvdbcr, which means pvDatabase Create Record. 4) pvdbcrAddRecord,pvdbcrProcessRecord,pvdbcrRemoveRecord, and pvdbcrTraceRecord are like what they replace. But they also allow the asLevel to be set when they are created. 5) pvdbcrScalar and pvdbcrScalarArray are new special records. They created records that have fields value, alarm, and timeStamp. value can have any of the allowed scalar types, i.e. boolean,byte,...,string.	2021-03-15 07:04:32 -04:00
