Class ManifestEvaluator

  • public class ManifestEvaluator
    extends java.lang.Object
    Evaluates an Expression on a ManifestFile to test whether the file contains matching partitions.

    For row expressions, evaluation is inclusive: it returns true if a file may match and false if it cannot match.

    Files are passed to eval(ManifestFile), which returns true if the manifest may contain data files that match the partition expression. Manifest files may be skipped if and only if the return value of eval is false.
