This page contains EDMInterface API sample code to show how to exploit the powerful features of EDMqueryMethodsEDMmapMethods. To run these samples, you need to create an EDMdatabase and compile the following schemas.

Sample 1:
...
EDMmapMethod with result as User Defined Status
This sample shows how to execute an EDMqueryMethod and pick up the result in a QueryResult table allocated in the calling clients heap memory. In the sample, input arguments to the Query are provided as SELECT type parametersexecutes an EDMmapMethod with no input parameters. It counts the number of property sets in the source model and returns the result as a user defined status. To run this sample, you need to have the EDMquerySchema IFC_Query_Samples_01 installed the EDMmodelServerthe EDMmapSchema CheckPropertySet. You also need to import the sample population IfcWall_0104.ifc. Note that the QueryResult table shows instances of the VIEW_ENTITY type defined in the EDMqueryShema.

Sample 2:
...
EDMmapMethod with Parameters and File Mapping
This sample executes an EDMqueryMethod. Input arguments to the Query are provided through an XML file. The output is returned as a QueryTable written to the an XML file on the calling clients EDMmapMethod with input parameters and file mapping between the logical file name 'result' and a file on the EDMthinClient local file system. To run this sample, you need to have the EDMquerySchema IFC_Query_Samples_01 installed the EDMmodelServerthe EDMmapSchema CheckPropertySet. You also need to import the sample population IfcWall_0104.ifc.

Sample 3:
...
EDMmapMethods with Expression Logging
This sample executes an EDMqueryMethod. Input arguments to the Query are provided through an XML strings. The output is returned as a QueryTable written to the an XML string allocated in the calling clients heap memory. This sample also use file mapping to have the EDMqueryMethod write a result file directly in the calling clients local fils system.EDMmapMethod with EDMvirtualMachine expression logging. To run this sample, you need to have the EDMquerySchema IFC_Query_Samples_01 installed the EDMmodelServerthe EDMmapSchema CheckPropertySet. You also need to import the sample population IfcWall_0104.ifc.
