Detailed Description

A ProxyEnvironment is the interaction point for dealing with managed objects. Managed objects can take a variety of forms. For example:

Member Typedef Documentation

Constructor & Destructor Documentation

virtual Pothos::ProxyEnvironment::~ProxyEnvironment ( void  )
virtual

Virtual destructor for subclassing.

Member Function Documentation

virtual Proxy Pothos::ProxyEnvironment::convertObjectToProxy ( const Object local)
virtual

Convert a local object into a proxy object in this environment.

Exceptions
ProxyEnvironmentConvertErrorif conversion failed
Parameters
localan Object that contains something in local memory
Returns
a new Proxy that represents the Object's contents
virtual Object Pothos::ProxyEnvironment::convertProxyToObject ( const Proxy proxy)
virtual

Convert a proxy object in this environment into a local object.

Exceptions
ProxyEnvironmentConvertErrorif conversion failed
Parameters
proxya Proxy that represents an object in the environment
Returns
a new Object that contains something in local memory
virtual Proxy Pothos::ProxyEnvironment::deserialize ( std::istream &  is)
pure virtual

Deserialize the stream into the contents of a Proxy.

Exceptions
ProxySerializeErroris the operation cant complete
Parameters
isthe input stream holding serialized data
Returns
a new proxy from the serialized data
virtual Proxy Pothos::ProxyEnvironment::findProxy ( const std::string &  name)
pure virtual

Find a proxy object given its class name. The resulting object will have calls to create class instances, make static calls, and others.

Exceptions
ProxyEnvironmentFindErrorif cannot find
Parameters
namethe name of a class in the registry
Returns
a Proxy representing the class
static std::string Pothos::ProxyEnvironment::getLocalUniquePid ( void  )
static

Static method to get the unique ID of the caller process. The ID is universally unique, based on the nodeId and pid.

virtual std::string Pothos::ProxyEnvironment::getName ( void  ) const
pure virtual

Get the name of the environment. This should be the same name passed into the factory.

virtual std::string Pothos::ProxyEnvironment::getNodeId ( void  ) const
virtual

Get the unique ID of the node that this environment is running on. Remote environments will report the node id of the remote server.

virtual std::string Pothos::ProxyEnvironment::getPeeringAddress ( void  )
virtual

Get the peering address of the connection for this environment. Remote environment will report the peering address of the caller as seen by the remote server's socket acceptor.

virtual std::string Pothos::ProxyEnvironment::getUniquePid ( void  ) const
virtual

Get the unique ID of the process that this environment is running on. Remote environments will report the process id of the remote server.

static Sptr Pothos::ProxyEnvironment::make ( const std::string &  name,
const ProxyEnvironmentArgs args = ProxyEnvironmentArgs() 
)
static

Create a new environment given the name of the factory. Plugins for custom BufferManagers should be located in the plugin registry: /proxy/environment/[name]

Exceptions
ProxyEnvironmentFactoryErrorif the factory function fails.
Parameters
namethe name of a ProxyEnvironment factory in the plugin tree
argsthe proxy environment init arguments
Returns
a new shared pointer to a proxy environment
template<typename ValueType >
Proxy Pothos::ProxyEnvironment::makeProxy ( const ValueType &  local)
inline

Convert a local object into a proxy object in this environment. Convenience templated version that takes the ValueType as input.

virtual void Pothos::ProxyEnvironment::serialize ( const Proxy proxy,
std::ostream &  os 
)
pure virtual

Serialize the contents of the proxy into a stream.

Exceptions
ProxySerializeErroris the operation cant complete
Parameters
proxythe input proxy object to serialize
osthe output stream for the serialized data
