builder

问题 I have classes that extend an abstract class and I don't want to put @Builder on top of the all child classes. Is there any way to implement Lombok @Builder for an abstract class? 回答1: Not possible at all. The builder is generated into the super class during compiling and it can not have any knowledge of the possible sub classes that will eventually implement it. For example, the sub class could have constructors that have to be used for the instance to have a valid state and Lombok can not

问题 I'm re-writing some code, and I've decided the way to recreate the class, as there are a fixed number of sheets, I'm creating them as enums. This is a decision based on the readability of a builder patter vs a telescoping constructor. The code I'm grabs some some .xls files, adds headers (and reads some from other .xls files) and perhaps some sub-sheets. It then merges a variety of these sheets together in a specific way to make tabs on a main excel workbook. My issue is that some of the

问题 I have the following simple class that I would like to use to notify user of incoming messages (I will evolve it as the app goes).

问题 I don't understand what is exactly a builder in CDT, and what is the relationship with the "C/C++ Build" content. I set up SCons in the "C/C++ Build" confuguration. It does work : I made two configurations (release and debug), and my SCons scripts are launched. But as I try now to debug, I am studying these Builders stauuf (I am discovering Eclipse...). The documentation is not clear at all about this point. Thanks for help. 回答1: I'm not exactly sure what your problem is, but I'll try to

问题 I recently started working with Eclipse's Plug-in development environment on Eclipse RCP (4.2.1 Juno). I created a project with the Incremental Builder Template. My goal is to perform a build process on the user code after Java Build is over. The problem is, I don't know how to use the Builder. I tried Exporting the project into a "Deployable Plug-ins and Fragments" jar file, and then placed the jar file in several places, like Development Workspace, Runtime Workspace, and in the plugins

问题 If I have an executable that generates an output from multiple files at a time - generate_output -o a.out -f input1.txt input2.txt input3.txt Is there a way to write such a custom builder for this? What I have at the moment is - builder = Builder( action='generate_output -o $TARGET -f $SOURCE', suffix='.out', src_suffix='.txt') Then it only generates files in a sequence, which is not what I really wanted - generate_output -o input1.out -f input1.txt generate_output -o input2.out -f input2.txt
