MemoryFolder Class

In This Topic

Specialization of the AbstractFolder class that implements access to a folder located in memory.

Object Model

Syntax

Visual Basic
C#

'Declaration
 
Public Class MemoryFolder 
   Inherits AbstractFolder

'Usage
 
Dim instance As MemoryFolder

public class MemoryFolder : AbstractFolder

Remarks

As long as you hold at least one instance on a MemoryFile or a MemoryFolder located in a specific root name, all files and folders in that same virtual ram drive stay alive. When a root name is no longer referenced, all its content will get garbage collected later.

To make sure the memory allocated for a MemoryFile's data is released, as soon as you don't need the file anymore, call FileSystemItem.Delete on that MemoryFile.
