CodecHolder

java.lang.Object
- org.omg.IOP.CodecHolder

All Implemented Interfaces:

Streamable
```
public final class CodecHolder
extends java.lang.Object
implements Streamable
```
The formats of IOR components and service context data used by ORB services are often defined as CDR encapsulations encoding instances of IDL defined data types. The Codec provides a mechanism to transfer these components between their IDL data types and their CDR encapsulation representations.
A Codec is obtained from the CodecFactory. The CodecFactory is obtained through a call to ORB.resolve_initial_references( "CodecFactory" ).
