Workflow learning-three steps of Activiti process definition management and three steps of activitiI. Preface
In the previous article, we made a macro introduction to Activiti through a small demo, which gave you an overall understanding of
compiler compiles a program, it compiles only one source file and generates the corresponding intermediate file (for the VC, the. obj file), and then the connector unifies all intermediate files to form an executable file. The problem is that when
The Declaration tells the compiler some information to assist the compiler in syntax analysis and avoid compiler errors. The definition is to tell the compiler to generate some code that will be used by the connector. That is, the Declaration is for
"Definition" and "declaration" of functions are not the same thing. The definition of function refers to the establishment of function function, including specifying function name, function value type, formal parameter and its type, function body,
Class Definition details in C ++
Member variables
Each class can have no members or multiple members. The members can be data, functions, or type aliases.
A class can contain several public, private, and protected parts. Members defined in the
