This service examines the files whose paths or URLs are specified in the filelist. The content of those files is concatenated, separated by a newline, and the result written to the specified outputfile. If the displayresults port has a value 'true', then the concatenation is also echoed to the results port. If the displayresults port does not have a value 'true', then no connection should be made to the results port.

Input ports

  • filelist - The possibly empty list of paths or URLs to the files to be concatenated. This is a mandatory parameter.
  • outputfile - The path to the file that will contain the result of concatenating the files listed in filelist. This is a mandatory parameter.
  • displayresults - A string that must contain a boolean value. If the string is 'true', then the result of concatenating the files is output to the results port. Even if the string is 'true', the result is always saved to the file specified by outputfile. This is an optional parameter.

Output ports

  • results - If the displayresults port has a value of 'true', then results contains the string corresponding to the concatenation of the files within filelist. If the displayresults port does not have a value 'true', then no connection should be made to the results port.
