This function will define one EDMprotectedData item in an EDMdataModel. An EDMprotectedData item can be one entityInstance, one instance type (one entity) or one instance type and all its sybtypes. The EDMprotectedData description is stored as "meta-data" in the actual model. This meta-data is implemented using USER_DEFINED_ENTITY.

Be aware of the options EXCLUDE_USER_DEFINED_ENTITIES and ONLY_USER_DEFINED_ENTITIES in the EDMwriteStepFile operations

The xpxDefineProtectedData() operation can only be successfully performed for callers that have ADMINISTRATOR rights to the actual model. The xpxDefineProtectedData() must be performed in an open EDMwriteTransaction. Any "condition" argument in the following functions are any legal EDMexpressX logical functions. Such expressions may contain invocations of any functions in the actual EDMmethodSchema (EDMquerySchema, EDMruleSchema, EDMmapSchema), in the actual underlying Express schema, any EDMsystemQuery, any built-in EDMexpressX functions, any Express built-in schema. The following constants are implemented for being used in such "conditions":

xpxCREATE_ACCESS	XPXSUPERUSERID	XPXCURRENTAGGRINDEX	XPXAPPEND_AGGR_ELEMENT	XPXDELETE_AGGR_ELEMENT_BY_INDEX
xpxWRITE_ACCESS	XPXCURRENTGROUPID	XPXCURRENTAGGRID	XPXADD_AGGR_ELEMENT	XPX_INSERT_AGGR_ELEMENT_BEFORE_INDEX
xpxREAD_ACCESS	XPXCURRENTATTRIBUTEVALUE	XPXNEWAGGRELEMENTVALUE	XPXGET_AGGR_ELEMENT_BY_INDEX
xpxDELETE_ACCESS	XPXNEWATTRIBUTEVALUE	XPXCREATE_AGGR	XPXGET_AGGR_ELEMENTS
xpxSELECT_ACCESS	XPXCURRENTATTRIBUTEID	XPXGET_AGGR_MEMBER_COUNT	XPXPUT_AGGR_ELEMENTS
XPXCURRENTUSERID	XPXCURRENTOPERATION	XPXPUT_AGGR_ELEMENT_BY_INDEX	XPXDELETE_AGGR_ELEMENTS_BY_VALUE

Arguments

1	Type	Name	Comment
2	GENERIC	modelId	The EDMdataModel to define the actual ProtectedData for Only ADMINISTRATOR's of the model are permitted to perform this operation successfully The actual EDMdataModel must be in an open EDMwriteTransaction
3	GENERIC	instanceTypeNameOrInstanceTypeIdOrInstanceId	An EntityInstanceId, an InstanceTypeId (entityId) or an InstanceTypeName (EntityName) that defines the EDMprotectedData item.
4	INTEGER	permittetOperations	Any combinations of xpxCREATE_ACCESS, xpxWRITE_ACCESS, xpxREAD_ACCESS, xpxDELETE_ACCESS, xpxSELECT_ACCESS .The default value is all set, i.e., all operations are legal
5	STRING	createCondition	Any legal textual logical EDMexpressX expression that be evaluated before an xpxCREATE_ACCESS operation. This operation must be evaluated to TRUE before the actual operation can be performed. The default value is NULL = no condition = TRUE
6	STRING	deleteCondition	Same as "createCondition" but for xpxDELETE_ACCESS operations
7	STRING	writeCondition	Same as "createCondition" but for xpxWRITE_ACCESS operations
8	STRING	readCondition	Same as "createCondition" but for xpxREAD_ACCESS operations
9	STRING	aggrOperationsCondition	Same as "createCondition" but for any operations on aggregates
10	STRING	selectCondition	Same as "createCondition" but for xpxSELECT_ACCESS operations
11	STRING	selectConditionFilter	Condition that will be "AND(ed)" to the conditions specified by the caller in an xpxSELECT_ACCESS operation the default value is NULL, i.e., no condition will be "AND(ed)" to the user specified select operation condition.
12	INTEGER	options	Default value is xpxEXCLUDE_ATTRIBUTES
13	GENERIC	attributeNameOrAttributeIdN	AttributeId or attributeName
14	INTEGER	attributeNOperations	Permitted operation on attribute, i.e., xpxREAD_ACCESS or xpxWRITE_ACCESS. Default is xpxREAD and xpxWRITE
15	STRING	attributeNCondition	Condition that will be evaluated before any access to this specified attribute. The default value is NULL = no condition = TRUE

Return Value

Options

Option	Comment
xpxSUBTYPES	Only effective when the actual "instanceTypeNameOrInstanceTypeIdOrInstanceId" is an instance type, then this options specifies that the actual EDMprotectedData item includes all subtypes of the specified EDMprotectedData item
xpxINCLUDE_ATTRIBUTES	Only attributes listed in the following arguments can be accessed
xpxEXCLUDE_ATTRIBUTES	All attributes except those listed in the following arguments can be accessed
