Transport layer modules¶

ItalaApi leverages the power of the GenTL standard for data transport. This means the core of the library implements the architecture defined by GenTL, allowing users to retrieve the nodemaps of the internal ItalaApi modules. By configuring the parameters on these nodemaps via GenApi, users can change the behavior of the transport layer.

The tables below show how to access each module’s nodemap for the different supported languages.

C++

GenTL Module	ItalaApi Interface	Method
System	`ISystem`	`GetNodeMap()`
Interface	`ISystem`	`GetInterfaceNodeMap(itfInfo)`
Local Device	`IDevice`	`GetTLDeviceNodeMap()`
Remote Device	`IDevice`	`GetNodeMap()`
Datastream	`IDevice`	`GetDatastreamNodeMap()`

GenTL Module	ItalaApi Handle	Function
System	(Global)	`SYS_GetNodeMap()`
Interface	(Global)	`SYS_GetInterfaceNodemap(itfInfo)`
Local Device	`H_DEVICE`	`DEV_GetTLDeviceNodeMap()`
Remote Device	`H_DEVICE`	`DEV_GetNodeMap()`
Datastream	`H_DEVICE`	`DEV_GetDatastreamNodeMap()`

.NET

Note

Feature names and types for the GenTL modules are standardized by the GenTL SFNC (GenTL Standard Feature Naming Convention), just as the SFNC standardizes features for GenICam devices. Please refer to the official GenTL SFNC document for information about particular features. Refer to the official GenTL specification to find a more in-depth description of the standard.
