CX_ITEM_PATTERN - Pattern

CX_ITEM_PATTERN

Class hierarchy
Description:

Variant parts. Variant parts are parts that are combined to one part, which differ in some characteristics, but actually all represent the same part. A good example of this is the screw. There is only one variant part for screws. In the characteristics (properties) of the screw is now entered, what makes the different screws different, e.g. the thread pitch, the length, the thread type, the diameter, the material etc.
So we have only one part with different characteristics.

Code example:
BeginTXN [ testTxn ] PlugSpace
testTxn Get(itemPointer.Item())

Result: the subpart, if there is one in the variant part, that corresponds exactly to the characteristics of the attributes that the testTxn contains. If no subpart was found, the variant part is returned.
If there are no attributes for the determination, an error is returned. This error can be avoided by either calling the function ItemWeak instead of Item, or by registering a message that is triggered when characteristics are missing (SetBindMessage).

The following diagram shows how variant parts, distinct subparts and their attributes are usually connected in the ClassiX system (using the global attribute "WIDTH" as an example):

Item OBJECTThe Item() function on the variant part checks whether the values of the characteristics in the plug space correspond exactly to the values of a subpart. If yes, the determined subpart is returned, otherwise the variant part. If the characteristics are missing for the determination, an error is displayed. This error can be avoided by either calling the function ItemWeak instead of Item, or by registering a message that is triggered when characteristics are missing (SetBindMessage)

ClearingObject STRING, INTEGEROBJECTFirst assignment to settlement objects

ConditionedFilter STRING, OBJECTOBJECTIf a formula is executed, all objects are searched sequentially in the plug space for the data field searched for. If there are not only documents in the plug space, for example a data member "transaction", but also simple values as objects, then the evaluation of the formula would bring an error, because the simple value would also try to read the data field "transaction", which it does not have. Here the solution is to put the ConditionedFilter in front of the desired data field:
ConditionedFilter("inherited(this, CX_LINK_TXN)").FirstSuccessorByCondition("type(TopTransaction())=CX_ITEM_DEMAND")
