|
|
|
|
The class ~DServerCmdCopy~ provides the functionality to copy the data of a
|
|
darray index to antoher darray, keeping the index. It is used in the
|
|
DArray::Clone() method and in the implementation of the ~put~ operator.
|
|
This class derives from ~DServerCmd~ class, which provides the basic
|
|
communication and run functionality.
|
|
|
|
The class ~DServerCmdCopyParam~ is a data class for the parameters used
|
|
during the execution of a ~DServerCmdCopy~ object.
