Class ShortcutUtils

java.lang.Object

org.apache.flink.table.planner.utils.ShortcutUtils

@Internal
public final class ShortcutUtils
extends Object

Utilities for quick access of commonly used instances (like FlinkTypeFactory) without long chains of getters or casting like (FlinkTypeFactory) agg.getCluster.getTypeFactory().
