Class Edb

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.

Edb

public Edb(long address,
 AddressSpace space)

Constructs a new Edb given the address of the edb structure

Method Details

address

Returns the address of this edb.

ceeedb_ceeosigr

public long ceeedb_ceeosigr()
                     throws IOException

Returns the ceeosigr address

Throws:

IOException - if an error occurred reading from the address space

ceeedbdba

public long ceeedbdba()
               throws IOException

Returns the ceeedbdba

Throws:

IOException - if an error occurred reading from the address space

getSampleEdb

public static Edb getSampleEdb(AddressSpace space)

Returns a "sample" Edb for the given address space. Note that for certain applications (CICS?) there can be more than one Edb per address space. Returns null if there is no Edb.

getFirstDll

public Dll getFirstDll()
                throws IOException

Returns the first in the chain of Dlls (or null if there aren't any).

Throws:

IOException - if an error occurred reading from the address space

getEnvVars

public Properties getEnvVars()
                      throws IOException

Return a java.util.Properties object containing the environment variables.

Throws:

IOException
