DALImpl getDALImplDelegate ()

Detailed Description

Implementation of Writable Data Access Layer (WDAL) interface. Enables adding, removing and modifying nodes in ConfigurationDataBase (CDB). Nodes are xml files organized in directories so that directory has a xml file named exactly as directory. For example node /alma/LAMP1 is valid CDB node if there is file /alma/LAMP1/LAMP1.xml. It is implemented as wraper around DAL.

void com.cosylab.cdb.jdal.WDALImpl.set_DAO ( String  curl,
String  xml 
) throws CDBRecordDoesNotExistEx, CDBFieldDoesNotExistEx, CDBRecordIsReadOnlyEx, CDBXMLErrorEx, CDBExceptionEx

Change content of a node identified by curl so given xml is scanned for differences which are applied. This function can be invoked with full expanded version of the existing xml with some changes or it can be invoked by small xml with only changes to be applied. For example to change parameter 'Timeot' in Manager we can pass as xml 

 
     <?xml version="1.0" encoding="ISO-8859-1"?>
  <Manager timeout="50.0">

and new value will be saved in the xml file.

Parameters:
curl uri for the CDB node
xml 
Exceptions:
CDBRecordDoesNotExistEx 
CDBFieldDoesNotExistEx 
CDBRecordIsReadOnlyEx 
CDBXMLErrorEx 
CDBExceptionEx
