servermanager Module

servermanager is a module for using paraview server manager in Python. One can always use the server manager API directly. However, this module provides an interface easier to use from Python by wrapping several VTK classes around Python classes.

Note that, upon load, this module will create several sub-modules: sources, filters and rendering. These modules can be used to instantiate specific proxy types. For a list, try “dir(servermanager.sources)”

Usually users should use the paraview.simple module instead as it provide a more user friendly API.

A simple example:

from paraview.servermanager import *

# Creates a new built-in session and makes it the active session.
Connect()

# Creates a new render view on the active session.
renModule = CreateRenderView()

# Create a new sphere proxy on the active session and register it
# in the sources group.
sphere = sources.SphereSource(registrationGroup="sources", ThetaResolution=16, PhiResolution=32)

# Create a representation for the sphere proxy and adds it to the render
# module.
display = CreateRepresentation(sphere, renModule)

renModule.StillRender()

paraview.servermanager.ActiveConnection = Connection (builtin:) [1]

Keeps track of all connection objects. Unless the process was run with –multi-servers flag set to True, this will generally be just 1 item long at the most.

paraview.servermanager.AnimateReader(reader, view)

This is a utility function that, given a reader and a view animates over all time steps of the reader. It creates an AnimationScene and add a new TimeAnimationCue in it.

When running from the GUI and python shell, prefer using the existing scene and cue to maintain time consistency in the application.

class paraview.servermanager.ArrayInformation(proxy, field, name)

Bases: object

Meta-information associated with an array. Use the Name attribute to get the array name.

Please note that some of the methods accessible through the ArrayInformation class are not listed by help() because the ArrayInformation objects forward unresolved attributes to the underlying object. See the doxygen based documentation of the vtkPVArrayInformation C++ class for a full list.

GetRange(component=0)

Given a component, returns its value range as a tuple of 2 values.

class paraview.servermanager.ArrayListProperty(proxy, smproperty)

Bases: paraview.servermanager.VectorProperty

This property provides a simpler interface for selecting arrays. Simply assign a list of arrays that should be loaded by the reader. Use the Available property to get a list of available arrays.

This read-only property contains the list of items that can be read by a reader.

DeselectAll()

Deselects all arrays.

GetAvailable()

Returns the list of available arrays

paraview.servermanager.Connect(ds_host=None, ds_port=11111, rs_host=None, rs_port=22221, timeout=60)

Use this function call to create a new session. On success, it returns a vtkSMSession object that abstracts the connection. Otherwise, it returns None.

There are several ways in which this function can be called:

• When called with no hosts, it creates a new session to the built-in server on the client itself.

• When called with ds_host and ds_port arguments, it attempts to connect to a server(data and render server on the same server) on the indicated host:port.

• When called with ds_host, ds_port, rs_host, rs_port, it creates a new connection to the data server on ds_host:ds_port and to the render server on rs_host: rs_port.

• All these connection types support a timeout argument in second. Default is 60. 0 means no retry, -1 means infinite retries.

paraview.servermanager.ConnectToCatalyst(ds_host='localhost', ds_port=22222)

Use this function to create a new catalyst session.

Creates a proxy. If session is set, the proxy’s session is set accordingly. If session is None, the current Session is used, if present. You should not have to use method normally. Instantiate the appropriate class from the appropriate module, for example: sph = servermanager.sources.SphereSource()

paraview.servermanager.CreateRenderView(session=None, **extraArgs)

paraview.servermanager.Fetch(input, arg1=None, arg2=None, idx=0)

A convenience method that moves data from the server to the client, optionally performing some operation on the data as it moves. The input argument is the name of the (proxy for a) source or filter whose output is needed on the client.

You can use Fetch to do three things:

If arg1 is None (the default) then all of the data is brought to the client. In parallel runs an appropriate append Filter merges the data on each processor into one data object. The filter chosen will be vtkAppendPolyData for vtkPolyData, vtkAppendRectilinearGrid for vtkRectilinearGrid, vtkMultiBlockDataGroupFilter for vtkCompositeData, and vtkAppendFilter for anything else.

If arg1 is an integer then one particular processor’s output is brought to the client. In serial runs the arg is ignored. If you have a filter that computes results in parallel and brings them to the root node, then set arg to be 0.

If arg1 and arg2 are a algorithms, for example vtkMinMax, the algorithm will be applied to the data to obtain some result. Here arg1 will be applied pre-gather and arg2 will be applied post-gather. In parallel runs the algorithm will be run on each processor to make intermediate results and then again on the root processor over all of the intermediate results to create a global result.

Optional argument idx is used to specify the output port number to fetch the data from. Default is port 0.

class paraview.servermanager.FieldDataInformation(proxy, idx, field)

class paraview.servermanager.Property(proxy, smproperty)

Bases: object

Generic property object that provides access to one of the properties of a server object. This class does not allow setting/getting any values but provides an interface to update a property using __call__. This can be used for command properties that correspond to function calls without arguments. For example, > proxy.Foo() would push a Foo property which may cause the proxy to call a Foo method on the actual VTK object.

For advanced users: Python wrapper around a vtkSMProperty with a simple interface. In addition to all method provided by vtkSMProperty (obtained by forwarding unknown attributes requests to the underlying SMProxy), Property and sub-class provide a list API.

Please note that some of the methods accessible through the Property class are not listed by help() because the Property objects forward unresolved attributes to the underlying object. To get the full list, see also dir(proxy.SMProperty). See also the doxygen based documentation of the vtkSMProperty C++ class.

property Name

Returns the name for the property

class paraview.servermanager.PropertyIterator(aProxy)

Bases: object

Wrapper for a vtkSMPropertyIterator class to satisfy the python iterator protocol. Note that the list of properties can also be obtained from the class object’s dictionary. See the doxygen documentation for vtkSMPropertyIterator C++ class for details.

Returns the key for the property last returned by the call to ‘__next__()’

GetProperty()

Returns the property last returned by the call to ‘__next__()’

GetProxy()

Returns the proxy for the property last returned by the call to ‘__next__()’

class paraview.servermanager.Proxy(**args)

Bases: object

one or more server manager objects. It also provides an interface to set and get the properties of the server side objects. These properties are presented as Python properties. For example, you can set a property Foo using the following:

proxy.Foo = (1,2)

or:

proxy.Foo.SetData((1,2))

or:

proxy.Foo[0:2] = (1,2)

For more information, see the documentation of the property which you can obtain with:

help(proxy.Foo).

This class also provides an iterator which can be used to iterate over all properties, e.g.:

proxy = Proxy(proxy=smproxy)
for property in proxy:
    print (property)

For advanced users: This is a python class that wraps a vtkSMProxy. Makes it easier to set/get properties. Instead of:

proxy.GetProperty("Foo").SetElement(0, 1)
proxy.GetProperty("Foo").SetElement(0, 2)

you can do:

proxy.Foo = (1,2)

or:

proxy.Foo.SetData((1,2))

or:

proxy.Foo[0:2] = (1,2)

Instead of:

proxy.GetProperty("Foo").GetElement(0)

you can do:

proxy.Foo.GetData()[0]

or:

proxy.Foo[0]

For proxy properties, you can use append:

proxy.GetProperty("Bar").AddProxy(foo)

you can do:

proxy.Bar.append(foo)

Properties support most of the list API. See VectorProperty and ProxyProperty documentation for details.

Please note that some of the methods accessible through the Proxy class are not listed by help() because the Proxy objects forward unresolved attributes to the underlying object. To get the full list, see also dir(proxy.SMProxy). See also the doxygen based documentation of the vtkSMProxy C++ class.

class paraview.servermanager.ProxyManager(session=None)

Bases: object

When running scripts from the python shell in the ParaView application, registering proxies with the proxy manager is the only mechanism to notify the graphical user interface (GUI) that a proxy exists. Therefore, unless a proxy is registered, it will not show up in the user interface. Also, the proxy manager is the only way to get access to proxies created using the GUI. Proxies created using the GUI are automatically registered under an appropriate group (sources, filters, representations and views). To get access to these objects, you can use proxyManager.GetProxy(group, name). The name is the same as the name shown in the pipeline browser.

This class is a python wrapper for vtkSMProxyManager. Note that the underlying vtkSMProxyManager is a singleton. All instances of this class will refer to the same object. In addition to all methods provided by vtkSMProxyManager (all unknown attribute requests are forwarded to the vtkSMProxyManager), this class provides several convenience methods.

Please note that some of the methods accessible through the ProxyManager class are not listed by help() because the ProxyManager objects forwards unresolved attributes to the underlying object. To get the full list, see also dir(proxy.SMProxyManager). See also the doxygen based documentation of the vtkSMProxyManager C++ class.

GetPrototypeProxy(group, name)

Returns a prototype proxy given a group and name. This is an SMProxy. This is a low-level method. You should not normally have to call it.

GetProxies(groupname, proxyname)

Returns all proxies registered under the given group with the given name. Note that it is possible to register more than one proxy with the same name in the same group. Because the proxies are different, there is no conflict. Use this method instead of GetProxy() if you know that there are more than one proxy registered with this name.

GetProxiesInGroup(groupname)

Returns a map of proxies in a particular group.

GetProxy(group, name)

Returns a Proxy registered under a group and name

Registers a proxy (either SMProxy or proxy) with the server manager

SaveState(filename, location=16)

UnRegisterProxy(groupname, proxyname, aProxy)

Unregisters a proxy.

class paraview.servermanager.ProxyNamespace(xmlGroups, session)

Bases: object

This class is a container for class types representing known proxies types. Conceptually, one can think of this a Python equivalent for a proxy group, however, due to legacy reasons, it can represent proxies in more than one proxy-group.

Class types are created on demand. All known proxies types can be determined using dir() call on this instance. This avoids having to define classes for all proxy types during initialization, thus speeding up initialization.

Use this function call to create a new session. On success, it returns a Session object that abstracts the connection. Otherwise, it returns None. In reverse connection mode, the client waits for a connection from the server (client has to be started first). The server then connects to the client (run pvserver with -rc and -ch option). The optional port specified the port to listen to.

paraview.servermanager.SaveState(filename, location=16)

Given a state filename, saves the state of objects registered with the proxy manager.
