从类复制的说明: OptimizerNode

Gets the name of this node, which is the name of the function/operator, or data source / data sink.

指定者:

getOperatorName 在类中 OptimizerNode

返回:

The node name.

getPossibleProperties

protected List<OperatorDescriptorSingle> getPossibleProperties()

指定者:

getPossibleProperties 在类中 SingleInputNode

computeOperatorSpecificDefaultEstimates
