BinaryOperatorInformation<IN1,IN2,OUT>	A class for holding information about a single input operator, such as input/output TypeInformation.
CollectionExecutor	Execution utility for serial, local, collection-based executions of Flink programs.
CompilerHints	A class encapsulating compiler hints describing the behavior of the user function.
DualInputOperator<IN1,IN2,OUT,FT extends Function>	Abstract operator superclass for all operators that have two inputs, like "Join", "CoGroup", or "Cross".
DualInputSemanticProperties	Container for the semantic properties associated to a dual input operator.
GenericDataSinkBase<IN>	Operator for nodes that act as data sinks, storing the data they receive.
GenericDataSourceBase<OUT,T extends InputFormat<OUT,?>>	Abstract superclass for data sources in a Pact plan.
Keys<T>
Keys.ExpressionKeys<T>	Represents (nested) field access through string and integer-based keys
