Class IncrementallyUpdatedFilterPredicateBuilderBase

java.lang.Object

org.apache.parquet.filter2.recordlevel.IncrementallyUpdatedFilterPredicateBuilderBase

All Implemented Interfaces:

FilterPredicate.Visitor<IncrementallyUpdatedFilterPredicate>

Direct Known Subclasses:

IncrementallyUpdatedFilterPredicateBuilder

public abstract class IncrementallyUpdatedFilterPredicateBuilderBase
extends Object
implements FilterPredicate.Visitor<IncrementallyUpdatedFilterPredicate>

The implementation of this abstract class is auto-generated by org.apache.parquet.filter2.IncrementallyUpdatedFilterPredicateGenerator

Constructs a IncrementallyUpdatedFilterPredicate from a FilterPredicate This is how records are filtered during record assembly. The implementation is generated in order to avoid autoboxing.

Note: the supplied predicate must not contain any instances of the not() operator as this is not supported by this filter.

the supplied predicate should first be run through LogicalInverseRewriter to rewrite it in a form that doesn't make use of the not() operator.

the supplied predicate should also have already been run through SchemaCompatibilityValidator to make sure it is compatible with the schema of this file.

TODO: UserDefinedPredicates still autobox however
