Member Function Documentation

◆ supportsSetting_flange_T_effector_nominal()

bool supportsSetting_flange_T_effector_nominal ( ) const
inlineoverridevirtual

if true, the TCP transform can be set in the robot firmware

Implements PlanningFrameInterface.

◆ uuid()

std::string uuid ( )
overrideprotectedvirtual

Unique identifier for stream.

Implements Stream.

◆ openImpl()

bool openImpl ( )
overrideprotectedvirtual

Open stream.

Returns whether the operation was successful. This method is responsible for allocating necessary resources, initializing device handles, and establishing connections to devices. Implementers should ensure that all one-time setup tasks are completed here.

Implements Stream.

◆ closeImpl()

bool closeImpl ( )
overrideprotectedvirtual

Close stream.

Returns whether the operation was successful. This method should be used to free any resources that were allocated during the openImpl() call and to disconnect from any devices. Implementers must ensure that all resources are properly released to avoid memory leaks.

Implements Stream.

◆ startImpl()

bool startImpl ( )
overrideprotectedvirtual

Start stream.

Returns whether the operation was successful. This method is intended to initiate the actual data readout process or to connect a callback function for data handling. Implementers should ensure that the stream is ready and producing data after this call.

Implements Stream.

◆ stopImpl()

bool stopImpl ( )
overrideprotectedvirtual

Stop stream.

Returns whether the operation was successful. This method should halt any ongoing data readouts or callbacks, effectively pausing the data flow to reduce CPU load. Implementers should ensure that the stream can be restarted after this call.

Implements Stream.

◆ doWork()

std::optional< WorkContinuation > doWork ( )
overrideprotectedvirtual

Create one StreamData and publish it (this function will be called at the desired frame rate) If this is not desired, you can do the following: return std::nullopt;.

Implements Stream.
