Re: [dsdp-tm-dev] create rse connections programmatically.
|
am i right here?
1)SystemViewConnectionAdapter stays intact.
2) so i've been wrong to let my tree node model class extend SystemViewConnectionAdapter. it should implement IHost. now i still need to let it implement IAdaptable.
3) in your code below replace IRemoteFile with IHost and replace SystemViewRemoteFileAdapter with SystemViewConnectionAdapter and replace SystemViewFileAdapterFactory with a class name i like i.e.
HolySystemViewHostAdapterFactory.
4) in your code below replace SystemViewFileAdapterFactory with HolySystemViewHostAdapterFactor.
regard,wei.

The shortcut for implementing ISystemViewElementAdapter
is to extend AbstractSystemViewElementAdapter, which provides much of the
generic implementation.
SystemViewConnectionAdapter is the correct
adapter for IHost. IHost is what you want.
When you provide your own adapter for
your own model objects, you need to register it. To do that, you
need to provide the following:
1) You implementation of ISystemViewElementAdapter
2) Your model object needs to implement
IAdaptable. Typically you'd implement getAdapter() as follows:
public
Object getAdapter(Class adapterType)
{
return
Platform.getAdapterManager().getAdapter(this,
adapterType);
}
3) You should provide an adapter factory
class. Here's an example of what we do for mapping IRemoteFile to
SystemViewRemoteFileAdapter where:
IRemoteFile is the model object
type
SystemViewRemoteFileAdapter is the ISystemViewElementAdapter
/**
*
This
factory
maps
requests
for
an
adapter
object
from
a
given
*
element
object.
This
is
for
the
universal
file
system.
*/
public
class
SystemViewFileAdapterFactory extends
AbstractSystemRemoteAdapterFactory
{
private
SystemViewRemoteFileAdapter fileAdapter
= new
SystemViewRemoteFileAdapter();
/**
*
Called
by
our
plugin's
startup
method
to
register
our
adaptable
object
types
*
with
the
platform.
We
prefer
to
do
it
here
to
isolate/encapsulate
all
factory
*
logic
in
this
one
place.
*/
public
void
registerWithManager(IAdapterManager manager)
{
manager.registerAdapters(this,
IRemoteFile.class);
}
/**
*
@see
IAdapterFactory#getAdapter(java.lang.Object,
java.lang.Class)
*/
public
Object getAdapter(Object adaptableObject, Class adapterType)
{
Object adapter = null;
if
(adaptableObject instanceof
IRemoteFile)
adapter = fileAdapter;
if
((adapter != null)
&& (adapterType == IPropertySource.class))
{
((ISystemViewElementAdapter)adapter).setPropertySourceInput(adaptableObject);
}
return
adapter;
}
}
4) Finally, you need to register the
adapter factory (for example, in your Activator at startup). Here's
how we do it for the files:
IAdapterManager manager = Platform.getAdapterManager();
svfaf
= new
SystemViewFileAdapterFactory();
svfaf.registerWithManager(manager);

| Re: [dsdp-tm-dev] create rse connections

of course thanks. i've got the last problem
i think. you said "Or you may
choose to create an ISystemViewElementAdapter for your object.".
yes i need to do this but there are 63 methods to implement for ISystemViewElementAdapter.
is there any shortcut to create a connection
like
---------------------------------
host = registry.createHost(
"SSH Only",
//System
Type Name //$NON-NLS-1$
hostName, //Connection
name
hostName, //IP
Address
"Connection
to Eclipse build site"); //description
//$NON-NLS-1$
---------------------------------------
but IHost is not what we want, is it?
i tried to let my tree node model class extend SystemViewConnectionAdapter.
but it does not seem to work and i never run into this bracket:
--------------------------------------
{
result.setPropertySourceInput(object);
result.setViewer(_view);
return
result;
}
--------------------------------------
please let me know what you would do here! regard,wei.

With your own view, you probably already have a content provider and a
label provider. If you want to reuse the existing RSE model objects
(i.e. connections, subsystems, filters, etc) there are adapters that can
help out the provider. The interface that these adapters implement
is ISystemViewElementAdapter. The interface has code to allow for
getting the icon, label and children of a particular node, as well as other
things, such as action contributions and properties.
The reason I point to the ScratchpadViewProvider, is that it's a good example
of a content and label provider that makes use of the ISystemViewelementAdapter.
Here's code from the provider that allows you to get at a ISystemViewElementAdapter
from a model object:
protected
ISystemViewElementAdapter getAdapterFor(Object object)
{
if
(object instanceof
IContextObject)
{
object = ((IContextObject)object).getModelObject();
}
if
(object instanceof
IAdaptable)
{
IAdaptable
adapt = (IAdaptable) object;
ISystemViewElementAdapter result = (ISystemViewElementAdapter)
adapt.getAdapter(ISystemViewElementAdapter.class);
if
(result != null)
{
result.setPropertySourceInput(object);
result.setViewer(_view);
return
result;
}
}
return
null;
}
Once you have a way to get at the adapter, you can use it to implement
the methods of the content provider and label provider as follows:
public
boolean
hasChildren(Object object)
{
ISystemViewElementAdapter
adapter = getAdapterFor(object);
if
(adapter != null)
{
if
(object instanceof
IContextObject)
{
return
adapter.hasChildren((IContextObject)object);
}
else
{
return
adapter.hasChildren((IAdaptable)object);
}
}
...
return
false;
}
public
Object[] getChildren(Object object)
{
return
getElements(object);
}
public
Object[] getElements(Object object)
{
Object[] results
= null;
Object element
= object;
if
(object instanceof
IContextObject)
{
element = ((IContextObject)object).getModelObject();
}
if
(element instanceof
IAdaptable)
{
ISystemViewElementAdapter adapter = getAdapterFor(element);
if
(adapter != null
&& adapter.hasChildren((IAdaptable)element))
{
if
(object instanceof
IContextObject)
{
results =
adapter.getChildren(new
NullProgressMonitor(), (IContextObject)object);
}
else
{
results =
adapter.getChildren(new
NullProgressMonitor(), (IAdaptable)object);
}
}
...
}
if
(results == null)
{
return
new
Object[0];
}
return
results;
}
public
String getText(Object object)
{
ISystemViewElementAdapter
adapter = getAdapterFor(object);
if
(adapter != null)
{
return
adapter.getText(object);
}
...
return
object.toString();
}
public
Image getImage(Object object)
{
Image image = null;
ISystemViewElementAdapter
adapter = getAdapterFor(object);
if
(adapter != null)
{
ImageDescriptor descriptor = adapter.getImageDescriptor(object);
if
(descriptor != null)
{
Object iobj = imageTable.get(descriptor);
if
(iobj == null)
{
image
= descriptor.createImage();
imageTable.put(descriptor,
image);
}
else
{
image
= (Image) iobj;
}
}
return
image;
}
...
return
null;
}
Once you have the content provider setup properly, then you just need to
make sure you populate the initial nodes of the tree as you wish (wiht
you connection folder objects). You might either hardcode the provider
to deal with your objects:
if (object instanceof
MyConnectionFolder)
{
...
}
Or you may choose to create an ISystemViewElementAdapter for your object.
Does this help?

Hi Wei,
For what you want to do, the current Remote Systems view will not work.
You could write your own view and reuse much of the RSE functionality.
In particular, you could have the label and content provider make
use of the SystemView adapters for the RSE model objects which you use.
For a simple example, you could take a look at: SystemScratchpadViewProvider.
This is what the scratchpad view does to display the same sorts
of things that the Remote Systems view displays. In this case, you'd
need to provide a new model object for these "connection folders"
as well as it's corresponding adapter.

Hello Wei,
I'm afraid that what you want to do is not possible
with our official API. It may be possible by deriving
from RSE SystemView, and implementing a custom
SystemViewContentProvider.
I'm copying the dsdp-tm-dev list. Please CC the list
for all such kinds of requests, since there might be
others who know the answer better than any individual.
DaveM, can you help?
Thanks,
