- Short description : Stream input to shared memory

Description
The box writes input to shared memory so that it can be read by another process. Stimuli and streamed matrices are supported, and transformed into a format that can be written into shared memory. Based on the input types, a metainfo variable will be created in shared memory that will specify which variables have which type. This way the client can know what it will be reading.
The box creates (via boost interprocess library) a shared memory and within it uniquely named variables for each input. When receiving chunks on its inputs, the box will write them to shared memory so that they can be read by another process. The box can write stimuli and streamed matrices, which are transformed in a format that can be written into shared memory. Based on the input types, a metainfo variable will be created in shared memory that will specify which variables have which type in shared memory. This way the client knows what it will be reading.
Inputs
The supported input stream types are StreamedMatrix and Stimulations. The stream type of the input can be changed by the user and additional inputs can be added.
1. prediction1
Default streamed matrix input.
- Type identifier : Streamed matrix (0x544a003e, 0x6dcba5f6)
Settings
1. SharedMemoryName
Name of the shared memory to be created. Default to 'SharedMemory_P300Stimulator'
- Type identifier : String (0x79a9edeb, 0x245d83fc)
- Default value : [ SharedMemory_P300Stimulator ]
