  Gets columns selector. It selects columns to import. The default behavior is to auto-generate all columns.

  Returns:

  The Function accepts the Iterable, array or ResultSet to select columns.

  • Returns int[] (IntArray in Kotlin) to select columns by indexes for the specified ResultSet.
  • Returns String[] to select columns by namesfor the specified ResultSet, dictionary or custom object.
  • Returns property getter array Function[](where T is the element type of collection, R is the property type)to select columns with custom column getters. In this case, getIncludeColumnsHeader() must be false. Otherwise, an exception will be thrown. Because we don't know the column names.
  • Returns named property getter array AbstractMap.SimpleEntry[](where K is column name String, V is property getter Function; For each Function, T is the element type of collection, R is the property type)to select columns with custom column names and custom column getters. In this case, getIncludeColumnsHeader() should be true. Otherwise, the column names will be ignored.
