org.apache.flink.datastream.impl

Class ExecutionEnvironmentImpl

java.lang.Object

org.apache.flink.datastream.impl.ExecutionEnvironmentImpl

All Implemented Interfaces:

org.apache.flink.datastream.api.ExecutionEnvironment

Direct Known Subclasses:

ExecutionContextEnvironment

public class ExecutionEnvironmentImpl
extends Object
implements org.apache.flink.datastream.api.ExecutionEnvironment

The implementation of ExecutionEnvironment.

IMPORTANT: Even though this is not part of public API, ExecutionEnvironment will get this class instance through reflection, so we must ensure that the package path, class name and the signature of newInstance() does not change.
