[Vala] vala-gen-introspect struct vs. object

["W. Michael Petullo" <mike flyn org>]

How does vala-gen-introspect differentiate between a basic struct and
an object? I am trying to generate a Vala API file for an object, but
vala-gen-introspect is classifying it as a struct:

<struct name="DMAPGstInputStream">
        <method name="new" symbol="dmap_gst_input_stream_new">
                <return-type type="GInputStream*"/>
                <parameters>
                        <parameter name="transcode_mimetype" type="gchar*"/>
                        <parameter name="src_stream" type="GInputStream*"/>
                </parameters>
        </method>
        <method name="new_buffer_cb" symbol="dmap_gst_input_stream_new_buffer_cb">
                <return-type type="void"/>
                <parameters>
                        <parameter name="element" type="GstElement*"/>
                        <parameter name="stream" type="DMAPGstInputStream*"/>
                </parameters>
        </method>
        <field name="parent" type="GInputStream"/>
        <field name="priv" type="DMAPGstInputStreamPrivate*"/>
</struct>

The object works fine in C, but I suspect I am naming something in a
non-standard way and this is confusing vala-gen-introspect. I just can't
figure out what.
