StrictMetricsEvaluator

java.lang.Object
- org.apache.iceberg.expressions.StrictMetricsEvaluator

```
public class StrictMetricsEvaluator
extends java.lang.Object
```
Evaluates an Expression on a DataFile to test whether all rows in the file match.
This evaluation is strict: it returns true if all rows in a file must match the expression. For example, if a file's ts column has min X and max Y, this evaluator will return true for ts < Y+1 but not for ts < Y-1.
Files are passed to eval(ContentFile), which returns true if all rows in the file must contain matching rows and false if the file may contain rows that do not match.
