InputLineReaderTask

Reads a file, whose path is given as input, and iterates over its lines, outputting each line as a string. Same behaviour as LineReaderTask, except for the file path.

Task reference

  • Service: CleverAge\ProcessBundle\Task\File\InputLineReaderTask
  • Iterable task

Accepted inputs

string: path of the file to read. An \UnexpectedValueException is thrown if the file does not exist or is not readable. When a different path is received, the previous file is dropped and the new one is opened.

Possible outputs

string: for each line, its raw content. The line break is not removed. Underlying class is SplFileObject, with the READ_AHEAD and SKIP_EMPTY flags.

Options

This task has no option.

Examples

  • Read every line of every file of a folder
