Member Functions
- virtual bool mi::rswservices::IState_context::create_user_state( const char* name, Uint32 timeout) [pure virtual]
-
Creates a user state by name. This state will persist between separate service calls and may be used to store user state information. Note that the created state does not become the current user state. Call set_user_state_name to use the new scope. If a timeout is specified then the deletion timer begins running immediately.
Parameters
- name
- the name of the state
- timeout
- if > 0 then the state is deleted this many seconds after its last usage
Returns
true if creation succeeded, false otherwise
- virtual bool mi::rswservices::IState_context::delete_user_state( const char* name) [pure virtual]
-
deletes the user state
Parameters
- name
- the name of the state
Returns
true if deletion succeeded, false otherwise
- virtual IMap* mi::rswservices::IState_context::get_attachments() const [pure virtual]
-
retrieves the global attachment object. These attachments will be provided to all context objects.
Returns
an object with which to manipulate attachments
- virtual nservices::IEvent_context* mi::rswservices::IState_context::get_event_context() const [pure virtual]
-
retrieves the event context. This context can be used to register any events the user state wishes to listen for.
Returns
the event context
- virtual nservices::IFactory* mi::rswservices::IState_context::get_factory() const [pure virtual]
-
retrieves a factory
Returns
the factory or NULL if neuray services is not initialized.
- virtual neuraylib::IPlugin_api* mi::rswservices::IState_context::get_plugin_api() const [pure virtual]
-
Get the IPlugin_api.
Returns
the plugin api
- virtual neuraylib::ITransaction* mi::rswservices::IState_context::get_user_state_transaction() [pure virtual]
-
Retrieves a transaction into the user state. If no user state has been set with set_user_scope_name then this returns NULL.
Returns
the transaction or NULL if user state is not set.
- virtual bool mi::rswservices::IState_context::set_execution_scope_name( const char* scope_name) [pure virtual]
-
Sets the name of the scope to use when executing commands. All service commands will be executed within this scope unless a service command explicitly changes scope. If this method is not called, or if the call fails, then the global scope is used by all commands.
Parameters
- scope_name
- the name of the scope
Returns
true if the scope exists, false otherwise
- virtual bool mi::rswservices::IState_context::set_user_state_name( const char* state_name) [pure virtual]
-
Sets the name of the state to use to store user state information. This state must already have been created with create_user_state. A transaction into this state can be retrieved with get_user_state_transaction. This transaction will be passed into all service commands and event handlers. It will also be used for RealityServer management purposes. Core commands will not use the user state in any way. If set_user_state_name is not called then no user state transaction is available and RealityServer uses a default state for management.
Parameters
- state_name
- the name of the state
Returns
true on success, false if state does not exist
