io.deephaven.parquet.base.materializers.LongFromUnsignedLongMaterializer

All Implemented Interfaces:

PageMaterializer

public class LongFromUnsignedLongMaterializer
extends Object
implements PageMaterializer

Materializes an unsigned 64-bit parquet int as a primitive long, rejecting values that exceed Long.MAX_VALUE rather than silently reinterpreting them as negative.
