Interface DeviceContext<DataType>

  • Type Parameters:
    DataType - Type of data which can be transferred from/to this device
    All Superinterfaces:
    Context

    public interface DeviceContext<DataType>
    extends Context
    Device context of the device plugin. If the device supports more functionality, it can be extended. Device plugins can have multiple device contexts. Plugins which need the specific device contexts should declare a dependency on the device plugin.
    • Method Detail

      • readData

        DataType readData()
                   throws java.io.IOException
        Read data from the device.

        From the CPU point of view, this should be an implementation of the "IN" operation. The device should return one elementary unit (e.g. byte) of its input data. I/O operations are considered as events that occurred onto this device.

        Returns:
        elementary data read from device
        Throws:
        java.io.IOException - if something goes wrong
      • writeData

        void writeData​(DataType value)
                throws java.io.IOException
        Writes/sends data to the device.

        From the CPU point of view, this is what the "OUT" instruction should use. The device should accept one elementary unit (e.g. a byte) of the output data. I/O operations are considered as events that occurred within this device.

        Parameters:
        value - data to be written to the device
        Throws:
        java.io.IOException - if something goes wrong
      • getDataType

        java.lang.Class<DataType> getDataType()
        Get the type of transferred data.
        Returns:
        type of transferred data
