java.lang.Object
- com.ibm.dtfj.corereaders.zos.le.Edb

```
public class Edb
extends Object
```
This class represents an LE Enclave Data Block. This provides access to such things as the chain of Dlls. Normally this object is obtained via the Caa, but as a convenience a method is provided to obtain one directly from an AddressSpace.
