Class ValueArrayFactory

java.lang.Object

org.apache.flink.graph.types.valuearray.ValueArrayFactory

public class ValueArrayFactory
extends Object

A factory generator for ValueArray types is necessary because the contained Value types do not currently implement a common interface for creating a ValueArray. Algorithms must instantiate classes at runtime when the type information has been erased.

This mirrors creating Value using CopyableValue.copy().
