| Description |
Copies Count bytes from the index SourceIndex in SourceBuffer to TargetIndex in TargetBuffer.
It does not matter what the primitive data types are in each array - the Buffer class treats each as a block of bytes.

| | Notes | Static methods are not methods of an object - they are simply class functions or procedures available at any time.
