Class PrimitiveComparator<T>

java.lang.Object

org.apache.parquet.schema.PrimitiveComparator<T>

All Implemented Interfaces:

Serializable, Comparator<T>

public abstract class PrimitiveComparator<T>
extends Object
implements Comparator<T>, Serializable

Comparator implementation that also supports the comparison of the related primitive type to avoid the performance penalty of boxing/unboxing. The compare methods for the not supported primitive types throw UnsupportedOperationException. Serializable implementation that may be a UserDefinedPredicate defined this Comparator is their member variable.
