OSResourceManager (P2J - Progress 4GL to Java Conversion and Runtime)

java.lang.Object
- com.goldencode.p2j.util.osresource.OSResourceManager

Direct Known Subclasses:

ClientSideResourceManager, ServerSideResourceManager
```
public abstract class OSResourceManager
extends java.lang.Object
```
Allows configuration of OS resources like memptr or library, to be remoted either from the server or client-side.
Server-side resources can be enabled via a directory configuration, per account, group, server or global. The directory node is:
```
 <node class="string" name="server-side-resources">
    <node-attribute name="value" value="memptr,library,streams">
 </node>
 
```
The special value all can be used to enable all OS resources at server-side, to not specify them by name.
