Copy and DeepCopy (Record functions)
Copy this Record object (Record class)
Deep copy this Record object (Record class)
Copy is a function that makes an exact copy of a Record object.
DeepCopy performs the identical function. Record objects are always copyable and "deep-copyable" (as these terms are described in "The Object class copy methods").
Syntax
%outRecord = record:DeepCopy[( [lockStrength], - [LoopLockStrength= lockStrength])]
Syntax terms
| %outRecord | A Record object created by this method that contains a copy of the method object. |
|---|---|
| record | A Record object variable. The variable can be Null, in which case the output object will also be Null. |
| lockstrength | A value of the LockStrength enumeration that is the lock strength to give to the instantiated Record object. Options are: None, Share, or Exclusive, as described in "New (Recordset constructor)". This is an optional parameter, and it defaults to the lock strength of the method object. |
| LoopLockStrength | The lock strength to be used for loops on the copied Record. This is an optional, name required, parameter, and it defaults to the LoopLockStrength of the method object Record. See "LoopLockStrength for Records". |
Usage notes
- Before Sirius Mods 7.0, Copy did not allow setting of the target lock strength. So, before Sirius Mods 7.0, to make a Record object copy with a different lock strength, the New or CurrentRecord (inside a For record loop) methods had to be used.
- Since a Record object and its copy reference the same underlying record, there generally isn't a good reason to make a copy of a Record object — it makes more sense to just assign the reference to the Record object. The copy functionality for Records is mainly for the support of DeepCopy of Record objects, the main value of which is to facilitate passing of these objects to and from daemons.
- The following example illustrates the use of the DeepCopy function:
%firstRec is object record in file geeks %currentRec is object record in file geeks ... %currentRec = %firstRec:deepcopy
