FUNCTION xpxValidateWhereRuleWithParametersBN (currInst : GENERIC;
whereRuleName : STRING;

Invokes the EDMmodelChecker to validate the specified instance against the specified local rule (Where rule). The specified local rule must be defined in the dictionary model (Express schema) that is the underlying schema of the data model that hosts the actual instance, or the local rule must be defined in an EDMruleSchema specified in the <ruleSchemaId> argument.
A number of arguments can be supplied to the ?where rule validation process? in the arguments argument1, ?, argumentN. Hence the validation process can be made parameterized. The validation process can return a value to the caller through the returnValue argument. The value to return must be set in the validation process by invoking the xpxReturnValueToCaller operation.
See related functions: xpxGetNumberOfUserParameters, xpxGetUserParameter
The data model that hosts the specified instance must be open before this operation can be successfully performed.
This function is equivalent to the EDMinterface function edmiValidateWhereRuleWithParametersBN. appropriate to the specified instance. The validation process can return additional information to the application through the <returnValue> argument. The data model that hosts the specified instance must be open before this operation can be successfully performed. The expressions logging can be used to log (trace) the execution of the local rule in the EDMexpressVM. The EDMsupervisor and the interactive EDMdebugger can be used for testing and debugging local rules as well as getting detailed information of a validation process.
Arguments
...
| Type | Name | Comment |
| GENERIC | currInst | A numeric instanceID that uniquely identifies the instance in the EDMdatabase to be validated. |
| STRING | whereRuleName | The name of the actual local rule (Where rule) to validate. Where rule names are case insensitive. When the <whereRuleName> is not unique within the specified instance, then the <whereRuleName> should be qualified with the name of the entity or defined type that declares the actual where rule. |
| GENERIC | ruleSchemaId | A numeric ruleSchemaID that uniquely identifies the rule schema instance in the EDMdatabase that defines the local rule specified in the <whereRuleName> argument. The specified where rule must be defined in the dictionary model (Express schema) that is the underlying schema of the data model that hosts the specified instance <instance> if the <ruleSchemaId> is set to zero. |
| STRING | userOutputFile | Specifies the name of a file that will be used to receive the result of executing the xpxPrintf and xpxOutputValue function during the validation operation. The specified file can be an existing file or the name of a file that will be created by the EDMmodelChecker. The default file extension is ".txt". The output from the xpxPrintf and xpxOutputValue function during the validation process will be written to the EDMinterface current output device when the <userOutputFile> is set to NULL. |
| LOGICAL | result | Address of a LOGICAL variable that will receive the result of the validation operation. The returned result is as follows:
|
| GENERIC | returnValue | Address of variable that will receive the value from the actual validation process. The actual value must be specified by invoking the xpxReturnValueToCaller procedure in the validation process in the EDMexpressVM |
| INTEGER | numberOfParameters | Specifies the number of parameters supplied in the actual invocation of the operation. |
| GENERIC | argument(n) | Actual parameter value. |
