wrapper business object
A top-level business object that groups child business objects for a component to use in a single operation or contains processing information about its child business object. See also request business object, response business object.
A collaboration that handles the verification or synchronization of a business object for another collaboration. Using a wrapper collaboration is important when a triggering business object references another top-level business object, as when an Order references Customer. To isolate and preserve the integrity of the referenced data, the first collaboration creates a business object for the referenced data and sends it to a specific wrapper collaboration for further handling.
A thread used to wrap an external thread so it can be treated as one of the application threads on the call stack. A wrapper thread can be suspended, resumed, can have its priority set, and can participate in animation.
A scan that starts between the boundaries of the range specified for that scan, continues to the upper boundary, returns to the lower boundary, and continues until it reaches its original starting place. For a table scan, the boundaries are the first and last pages of the table. For a range scan, the boundaries are the first and last pages of the data partition. For an index-driven scan, the boundaries are the start and end keys of the scan range.
A configuration in which the maximum client wrap size setting is greater than 0. The total size of Client daemon binary trace files is limited to the value specified in the Maximum Client wrap size setting.

- For devices, a diagnostic test that returns the output of a device as input.
- A test that checks attachment or controller circuitry (without checking the connected device) by returning the output of the attachment of controller circuitry as input. For example, when irrecoverable communications adapter or machine errors occur, the wrap test can transmit a specific character pattern to or through the modem in a loop and then compare the character pattern received to what was transmitted.
