在flink的function类中传递参数,对于flink datastream和dataset是不同的,对于dataset,可以通过类构造函数、withParameters(Configuration)、全局参数、广播变量等方法,详细参考:https://ci.apache.org/projects/flink/flink-docs-stable/dev/batch/。对于datastream,常用的是类构造函数、ParameterTool,参考:https://ci.apache...
If you prefer named parameters, it's possible (with a few tricks) to actually pass named parameters to functions (also makes it possible to pass arrays and references). The method I developed allows you to define named parameters passed to a function like this: function example { args : st...

It highlights the flexibility of passing methods as parameters in C# using the Action delegate, particularly when dealing with methods that don’t return a value. Conclusion Passing methods as parameters in C# using delegates empowers you to write more modular and flexible code. Whether you’re ...
Finally, collapseRows allows the user to input their own user-defined aggregation function (by setting method = "function" and passing the desired function using methodFunction), which affords maximum flexibility. Network methods for collapsing rows Correlation network methods for collapsing variables ...
