Package 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.

  • Method Details

    • newInstance

      public static org.apache.flink.datastream.api.ExecutionEnvironment newInstance()
      Create and return an instance of ExecutionEnvironment.

      IMPORTANT: The method is only expected to be called by ExecutionEnvironment via reflection, so we must ensure that the package path, class name and the signature of this method does not change.
