                                Connection connection)
        INTERNAL: This method is used to unwrap the oracle connection wrapped by the application server. TopLink needs this unwrapped connection for certain Oracle Specific support. (ie TIMESTAMPTZ, LOB) This is added as a workaround for bug 4565190

        INTERNAL Used by SQLCall.translate(..) Typically there is no field translation (and this is default implementation). However on different platforms (Oracle) there are cases such that the values for binding and appending may be different (BLOB, CLOB). In these special cases the method returns a wrapper object which knows whether it should be bound or appended and knows how to do that.
