Class TestFileScanFramework.MockFileReaderFactory

java.lang.Object

org.apache.drill.exec.physical.impl.scan.file.FileScanFramework.FileReaderFactory

org.apache.drill.exec.physical.impl.scan.TestFileScanFramework.MockFileReaderFactory

All Implemented Interfaces:

ManagedScanFramework.ReaderFactory

Enclosing class:

TestFileScanFramework

public static class TestFileScanFramework.MockFileReaderFactory
extends FileScanFramework.FileReaderFactory

Mock file reader that returns readers already created for specific test cases. Verifies that the readers match the file splits (which were obtained from the readers.)

This is not a good example of a real file reader factory, it does, however, illustrate a design goal to allow a variety of implementations through composition.
