## org.apache.axis.attachments
Interface Attachments

All Superinterfaces:
  java.io.Serializable

All Known Implementing Classes:
  AttachmentsImpl

public interface Attachments
extends java.io.Serializable

Access the Attachments of a Message. This interface essentially firewalls the rest of Axis from any dependencies on javax.activation.

If javax.activation is not available, this is the *only* class that will be compiled in org.apache.axis.attachments.
