BaseDelegatingExecutionFactory (Teiid 8.0.0.Final API)

java.lang.Object
- org.teiid.translator.ExecutionFactory<F,C>
- - org.teiid.translator.BaseDelegatingExecutionFactory<F,C>

All Implemented Interfaces:

DelegatingExecutionFactory<F,C>
```
public class BaseDelegatingExecutionFactory<F,C>
extends ExecutionFactory<F,C>
implements DelegatingExecutionFactory<F,C>
```
Base delegating translator. Will proxy all calls to another ExecutionFactory. You will create a custom translator as a subclass of this class containing overrides for any method you wish to intercept. Given that subclass is given a Translator name of 'custom-delegator', your 'vdb.xml' file will contain an XML fragment like the following to assign the delegate:
```
 <translator type="custom-delegator" name="my-translator" description="custom translator">
    <property value="delegateName" name="name of the delegate instance"/>
    
 </translator>
 
```
