Package org.apache.parquet.filter2.predicate

Interface FilterPredicate.Visitor<R>

Type Parameters:

R - return type of the visitor

All Known Subinterfaces:

ColumnIndex

All Known Implementing Classes:

ColumnIndexFilter, IncrementallyUpdatedFilterPredicateBuilder, IncrementallyUpdatedFilterPredicateBuilderBase, LogicalInverseRewriter, LogicalInverter, SchemaCompatibilityValidator

Enclosing interface:

FilterPredicate

public static interface FilterPredicate.Visitor<R>

A FilterPredicate Visitor must visit all the operators in a FilterPredicate expression tree, and must handle recursion itself, per the visitor pattern.
