EdmiError edmiValidateModel(SdaiModel       dataModelId,
                             SdaiString      diagnosticFile, 
                             SdaiInteger     options, 
                             SdaiRuleSchema  ruleSchemaId, 
                             SdaiString      userOutputFile, 
                             SdaiInstance    *validationErrorId);

This function invokes the EDMmodelChecker to validate all instances in the specified data model against the rules and constraints specified in the <options> argument.

...

The result of the validation can be a text report, a population of the Express schema EDM_Validation_Result_Schema or both. A population of the EDM_Validation_Result_Schema enables the caller to make his own diagnostic report in his own format.

...

There exist two options that will influence the amount of information in the validation report produced by this function: NO_PRINT_OUTPUT and FULL_OUTPUT

...

. A standard validation report will be produced when none of these options are set in the <options> argument. A validation report with all available detailed information is produced when the FULL_OUTPUT option is set. No validation report will be produced when the NO_PRINT_OUTPUT option is enabled. The validation result would then normally be in a population of the EDM_Validation_Result_Schema.

...

When validating data model against rules specified in an EDMruleSchema, only he following validation options are effective: FULL_VALIDATION, GLOBAL_RULES, LOCAL_RULES, UNIQUENESS_RULES. FULL_VALIDATION means in this context: GLOBAL_RULES | LOCAL_RULES | UNIQUENESS_RULES.

...

This function is only applicable to data models.

...

The data model that holds the instance to validate must be open before this operation can be successfully performed.

...

The expressions logging can be used to log (trace) the execution of the validation process in the EDMexpressVM. The EDMsupervisor and the interactive EDMdebugger can be used for testing and debugging the rules as well as getting detailed information of a validation process.

Arguments

...

Type	Name	Comment
SdaiModel	dataModelId	A numeric modelID that uniquely identifies the model in the EDMdatabase to validate.

The modelID is returned from the functions: sdaiCreateModel , sdaiCreateModelBN , sdaiOpenModelBN , edmiGetModel , edmiGetModelBN , sdaiGetInstanceModel
SdaiString	diagnosticFile	Specifies the file name for diagnostic information generated by this function. If no file name is supplied, i.e. the <diagnosticFile> argument is set to NULL, all diagnostic information will be written to the EDMinterface current output device. The EDMinterface current output device can be defined by the edmiDefineOutputFunction operation.

No diagnostics report will be produced by this function when the NO_PRINT_OUTPUT option is set.
SdaiInteger	options	Specifies the enabled options used by the EDMmodelChecker in the current invocation. The <options> value is specified as a bitwise OR between the enabled options. All option names are defined in the header file sdai.h .

See detailed descriptions of the available options below.
SdaiRuleSchema	ruleSchemaId	A numeric ruleSchemaID that uniquely identifies the rule schema instance in the EDMdatabase that defines the rules to be validated in this operation.

The ruleSchemaID can be retrieved by the edmiGetRuleSchema operation.
SdaiString	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. The EDMinterface current output device can be defined by the edmiDefineOutputFunction operation.
SdaiInstance	validationErrorId	The address of a variable of type SdaiInstance that will receive a numeric instanceID that uniquely identifies an instance of type validation_error in a population of the EDM_Validation_Result_Schema that contains all details of the violations detected in the last invocation of the EDMmodelChecker.

No population of the EDM_Validation_Result_Schema will be produced when the <validationErrorId> argument is NULL on input.

GLOBAL_RULES	Specifies that all global rules appropriate for the specified

data model

instance will be validated

against all

LOCAL_RULES	Specifies that all local rules (Where rules) appropriate for the specified

data model

(Where rules)

are defined in the appropriate dictionary model (Express schema) or defined in the specified EDMruleSchema.
INVERSE_RULES	Specifies that

the specified data model will be validated against

all Inverse constraints defined
