CloneDeep()

• Create a copy of Projection using the deep clone process.

• The difference between deep clone and shallow clone is as follows: In shallow cloning, only the object is copied; the objects within it are not. By contrast, deep cloning copies the cloned object as well as all the objects within.

• Type:Projection
• Description:A cloned Projection.

Open()

• This method opens the projection and gets it ready to use.

• This method opens the projection and gets it ready to use. As this is a concrete public method that wraps a Core method, we reserve the right to add events and other logic to pre- or post-process data returned by the Core version of the method. In this way, we leave our framework open on our end, but also allow you the developer to extend our logic to suit your needs. If you have questions about this, please contact our support team as we would be happy to work with you on extending our framework.

OpenCore()

• This method opens the projection and gets it ready to use.

• As this is the core version of the Open method, it is intended to be overridden in an inherited version of the class. When overriding, you will be responsible for getting the projection classes' state ready for doing projections.

• Type:Void
• Description:None

CloseCore()

• This method closes the projection and gets it ready for serialization if necessary.

• As this is the core version of the Close method, it is intended to be overridden in an inherited version of the class. When overriding, you will be responsible freeing any state you have maintained and getting the class ready for serialization if necessary. Note that the object may be opened again, so you want to make sure you can open and close the object multiple times without any ill effects.
