Member Function Documentation

GenData()

std::vector< ImageTopic > ExamplePixelsShmPub::GenData ( int num_frames )

inlineoverridevirtual

Generates data to be circulated.

This is a pure virtual function that must be overloaded by a child class in user code. The user code must allocate the necessary vector of the appropriate size (typically num_frames), fill the vector with generated data, and then return the vector.

If an exception is thrown from this method the process will terminate early with an error message.

Parameters

num_frames

The number of frames for which to generate data.

Returns

A vector of data points of type TopicType, i.e. std::vector<TopicType>. The size of the vector should typically be equal to num_frames.

Implements rtctk::standaloneTools::ShmPub< ImageTopic >.

ReadFits()

std::vector< ImageTopic > ExamplePixelsShmPub::ReadFits ( std::string filename )

inlineoverridevirtual

Reads in data from a FITS file.

This is a pure virtual function that must be overloaded by a child class in user code. The user code must allocate the necessary vector of the appropriate size, perform all FITS file access and handling, and return the filled vector containing the data.

If an exception is thrown from this method the process will terminate early with an error message.

Parameters

filename

The name of the FITS file to read from.

Returns

A vector of data points of type TopicType, i.e. std::vector<TopicType>.

Implements rtctk::standaloneTools::ShmPub< ImageTopic >.
