- Field Detail
  - null_pages
```
public List<Boolean> null_pages
```
    A list of Boolean values to determine the validity of the corresponding min and max values. If true, a page contains only null values, and writers have to set the corresponding entries in min_values and max_values to byte[0], so that all lists have the same length. If false, the corresponding entries in min_values and max_values must be valid.
  - min_values
```
public List<ByteBuffer> min_values
```
    Two lists containing lower and upper bounds for the values of each page. These may be the actual minimum and maximum values found on a page, but can also be (more compact) values that do not exist on a page. For example, instead of storing ""Blart Versenwald III", a writer may set min_values[i]="B", max_values[i]="C". Such more compact values must still be valid values within the column's logical type. Readers must make sure that list entries are populated before using them by inspecting null_pages.
  - max_values
```
public List<ByteBuffer> max_values
```
  - boundary_order
```
public BoundaryOrder boundary_order
```
    Stores whether both min_values and max_values are orderd and if so, in which direction. This allows readers to perform binary searches in both lists. Readers cannot assume that max_values[i] <= min_values[i+1], even if the lists are ordered.
