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

Sample 1: EDMruleMethod with logical output
This sample executes an EDMruleMethod with no input parameters and returns a single logical validation result (TRUE/FALSE/UNKNOWN). To run this sample, you need the EDMruleSchema IFC_Rule_Samples_01. You also need to import the sample population IfcWall_02.ifc.

2: EDMruleMethod with Expression Logging
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 parametersspecify expression logging of the EDMvirtualMachine that executes an EDMruleMethod. To run this sample, you need to have the EDMquerySchema EDMruleSchema IFC_QueryRule_Samples_01 installed the EDMmodelServer. You also need to import the sample population IfcWall_0102.ifc. Note that the QueryResult table shows instances of the VIEW_ENTITY type defined in the EDMqueryShema.

EDMruleMethod with XML
...
String I/O
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 EDMruleMethod with input parameters and file mapping between the logical file name 'result' and a file on the calling clients local file system. To run this sample, you need to have the EDMquerySchema EDMruleSchema IFC_QueryRule_Samples_01 installed the EDMmodelServer. You also need to import the sample population IfcWall_0102.ifc.

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.

4: Processing the EDMvalidation Result Model programatically
Whenever vaildating a data model a generic diagnostic file with all violations is produced. It might, however, be that one in a certain context wants to apply a filter.
Some types of errors might be critical in a certain context whereas others can be ignored. Moreover, it can also be helpful to show context specific identification of the the instances that cause the problem, in order to pin point the problem.
Therefore one can switch on an option to produce a so called validation result model whenever validating a data model. After the validation is finished, the validation result model can be processed programatically.
The example is written in Java (edom3). A detailed documentation is found in the header of the Validation class in the example.
