Methods of copying the data and their characteristics

Method CopyTo()

To get a separate instance of the data object, you can use the method CopyTo declared in DataObject.

CreateDataObjectsCopy = true

This is a flag that enables copying related objects (datalow and masters).

And the master are copied as objects, and not just put a link to them.

• If you copy an object that has detaily, then they too will make a copy.
• If the copied object detail will create a full backup and its aggregator (with all its detaylari).

PrimaryKeyCopy

Manages copy primary key (valid on your key, keys, master keys metalowych objects).

• true: primary keys will be taken from the source object
• false: primary keys are re-generated

copy of the data objects

Another important feature of this method is that is copied and link your data (is a single object copies the data to 2 instances of the data object). And the flag PrimaryKeyCopy is not affected - in copies of the data will remain the primary key, which was to be copied.

We do not guarantee adequate condition copy of the data after the method call CopyTo. Use the methods InitDataCopy or clearDataCopy after calling CopyTo .

Context-dependent cache data objects (DataObjectCache)

Reproduction occurs with the use of the object cache data. This means that with repeated reference to the object, verify its availability in the cache (the key is “the type of the primary key of the object”) and only after this, is either create or use already created is found in the cache.

If the task is to copy the data object is one to one without using the cache (for example, if 2 masters of the same type with the same key has been downloaded with different data sets and the need to prevent the widespread use of the first of them), it is recommended to apply the method CopyToObjectWithoutCache.
