java.lang.Object

org.apache.flink.ml.common.MLEnvironment

public class MLEnvironment
extends Object

The MLEnvironment stores the necessary context in Flink. Each MLEnvironment will be associated with a unique ID. The operations associated with the same MLEnvironment ID will share the same Flink job context.

Both MLEnvironment ID and MLEnvironment can only be retrieved from MLEnvironmentFactory.
