Method Detail

lookupExecutor

                                      StreamExecutionEnvironment executionEnvironment)

fromStreamInternal

execEnv

@Internal
public StreamExecutionEnvironment execEnv()

This is a temporary workaround for Python API. Python API should not use StreamExecutionEnvironment at all.

extractTypeInformation

protected <T> TypeInformation<T> extractTypeInformation(Table table,
                                                        Class<T> clazz)

protected <T> DataStreamQueryOperation<T> asQueryOperation(DataStream<T> dataStream,
                                                           Optional<List<Expression>> fields)

validateTimeCharacteristic

protected void validateTimeCharacteristic(boolean isRowtimeDefined)

qualifyQueryOperation

protected QueryOperation qualifyQueryOperation(ObjectIdentifier identifier,
                                               QueryOperation queryOperation)

Description copied from class: TableEnvironmentImpl

Subclasses can override this method to transform the given QueryOperation to a new one with the qualified object identifier. This is needed for some QueryOperations, e.g. JavaDataStreamQueryOperation, which doesn't know the registered identifier when created (fromDataStream(DataStream). But the identifier is required when converting this QueryOperation to RelNode.

Overrides:

qualifyQueryOperation in class TableEnvironmentImpl

attachAsDataStream

public void attachAsDataStream(List<ModifyOperation> modifyOperations)
