Package org.apache.flink.datastream.impl

Class 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 Detail

      • 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.
