edmiValidateInstance

This function invokes the EDMmodelChecker to validate a particular instance.
The result of the validation can either be a text report or a population of the EXPRESS schema EDM_Validation_Result_Schema. The latter case 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 an instance against rules specified in an EDMruleSchema, only he following validation options are effective: FULL_VALIDATION, GLOBAL_RULES, LOCAL_RULES, and UNIQUENESS_RULES. FULL_VALIDATION means in this context: GLOBAL_RULES | LOCAL_RULES | UNIQUENESS_RULES .
This function is only applicable to application instances.
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.

Prototype:
EdmiError edmiValidateInstance(SdaiAppInstance currInst,
                                SdaiString      diagnosticFile,
                                SdaiInteger     options,

                                SdaiInstance    *validationErrorId);
Arguments:

currInst	Specifies a numeric instanceID that uniquely identifies an application instance in the EDMdatabase to be validated. This instanceID is returned when the actual instance is created by the sdaiCreateInstance or sdaiCreateInstanceBN operations.
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.
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 .
ruleSchemaId	A numeric ruleSchemaID that uniquely identifies the rule schema instance in the EDMdatabase that defines the global rule specified in the <globalRuleName> argument. The specified global rule must be defined in the dictionary model (Express schema) that is the underlying schema of the specified data model <modelId> if the <ruleSchemaId> is set to zero. The ruleSchemaID can be retrieved by the edmiGetRuleSchema operation.
userOutputFile	Specifies the name of a file that will be used to receive the result of executing the xpxPrintf and xpxOutputValue function in the actual global rule. 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 of the xpxPrintf and xpxOutputValue function in the actual global rule 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.
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.

Option Description

FULL_VALIDATION	Specifies that the actual instance will be validated against all rules and constrains that is applicable for this particular instance. When the argument <ruleSchemaId> is specified unequal to zero, this options means the following options: GLOBAL_RULES	LOCAL_RULES	UNIQUENESS_RULES
GLOBAL_RULES	Specifies that all global rules appropriate for the specified instance will be validated. These global rules are defined in the appropriate dictionary model (Express schema) or defined in the specified EDMruleSchema.
LOCAL_RULES	Specifies that all local rules (Where rules) appropriate for the specified instance will be validated. These local rules are defined in the appropriate dictionary model (Express schema) or defined in the specified EDMruleSchema.
INVERSE_RULES	Specifies that all Inverse constraints defined for the actual instance will be validated. This option is not applicable when the argument <ruleSchemaId> is set unequal zero.
UNIQUENESS_RULES	Specifies that all Uniqueness rules defined for the actual instance will be validated.
REQUIRED_ATTRIBUTES	Specifies that all mandatory attributes, i.e., all explicit attributes that are not declared to be OPTIONAL, of the instance will be checked for an assigned value, i.e., checked that the attribute values are set. This option is not applicable when the argument <ruleSchemaId> is set unequal zero.
ATTRIBUTE_DATA_TYPE	Specifies that all attribute values of the instance will be checked for legal data type. This option is not applicable when the argument <ruleSchemaId> is set unequal zero.
AGGREGATE_DATA_TYPE	Specifies that all element values in all aggregates owned by the specified instance will be checked for legal data type. This option is not applicable when the argument <ruleSchemaId> is set unequal zero.
AGGREGATE_SIZE	Specifies that the number of elements in all aggregates owned by the specified instance is according to the related aggregate declarations. This option is not applicable when the argument <ruleSchemaId> is set unequal zero.
ARRAY_REQUIRED_ELEMENTS	Specifies that all elements in arrays, that are not declared as OPTIONAL, owned by the instance, will be checked for an assigned value, i.e., checked that no unset elements exists. This option is not applicable when the argument <ruleSchemaId> is set unequal zero.
AGGREGATE_UNIQUENESS	Specifies that all aggregates owned by the specified instance will be validated for uniqueness violation. Aggregates that have an uniqueness constraints are all SET aggregates, and ARRAY and LIST aggregates that are declared with the optional keyword UNIQUE. This option is not applicable when the argument <ruleSchemaId> is set unequal zero.
UNSET_DERIVE_ATTRIBUTES	Specifies that warnings will be issued if unset derived attributes are found. This option is not applicable when the argument <ruleSchemaId> is set unequal zero.
OUTPUT_STEPID	Specifies that the stepID corresponding to the instanceID will be written to the validation report when the actual correspondence exists in a STEP Identifier model.
FULL_OUTPUT	Specifies that all available information about the source of the errors will be recorded in the diagnostic report from this command.
STOP_ON_FIRST_ERROR	Specifies that the validation process should terminate when the first error is detected.

Returns:
A completion code of datatype EdmiError is the returned function value. The completion code has the following values:
Completion code = 0 : Operation successfully performed.
Completion code != 0: Error in operation. Completion code is an EDMinterface error code. Use edmiGetErrorText to get the error text corresponding to the error code.
