	Increments the reference counter of this object. Uses relaxed memory ordering since incrementing only requires atomicity, not synchronization with other memory operations.
int	DecrementRefCounter () noexcept
	Decrements the reference counter of this object; returns the decremented value. Uses release ordering for the decrement to ensure all writes to the object are visible before the count reaches zero. An acquire fence is added only when the count reaches zero, ensuring proper synchronization before deletion. This is more efficient than using acq_rel for every decrement.

	Memory deallocator for transient classes.

Detailed Description

Base class to make transfer process. Reads or Writes specialized CAD files into/from OCCT. Each operation needs the Configuration Node.

Providers are grouped by Vendor's name and Format type. The Vendor name is not defined by default. The Format type is not defined by default. The import process is not supported. The export process is not supported.

The algorithm for standalone transfer operation: 1) Create new empty Provider object 2) Configure the current object by special Configuration Node (::SetNode) 3) Initiate the transfer process: 3.1) Call the required Read method (if Read methods are implemented) 3.2) Call the required Write method (if Write methods are implemented) 4) Validate the output values
