Method Detail

createChannel

public DataChannel createChannel(java.lang.String name,
                                 java.util.Map<java.lang.String,java.lang.String> attributeMap,

                                 Emu emu,
                                 EmuModule module,
                                 int outputIndex)
                          throws DataTransportException

This method creates a DataChannel object.

Parameters:

name - name of DataChannel

attributeMap - hashmap of attributes taken from XML config file

isInput - true if this channel puts data into the Emu, else false

emu - Emu owning this transport

module - module creating this channel

outputIndex - order in which module's events will be sent to this output channel (0 for first output channel, 1 for next, etc.).

Returns:

DataChannel object

Throws:

DataTransportException - if transport problem
