How to recognize zero records in source flat file?I read a flatfile and I should ABORT () if there are no incoming records. How I can do this? The source file is on Unix, so I could use shell scripts, but I would to do this in Informatica....Another questions:can I use Unix pipe as input ("flat")file? A fast method to determine which record I'm processing now? i.e. See similar questions...

C# is a new language designed by Microsoft to work with the .NET framework. In their "Introduction to C#" whitepaper, Microsoft describe C# as follows: C# is a simple, modern, object oriented, and type-safe programming language derived from C and C++. C# (pronounced "C sharp") is firmly planted in the C and C++ family tree of languages, and will immediately be familiar to C and C++ programmers. C# aims to combine the high productivity of Visual Basic and the raw power of C++. See similar questions...

If you prefer the OO style, we recommend writing a small library that produces GDL from your internal graph class. This is usually quite straightforward, and the additional overhead is small as compared to the complexity of the layout task. See similar questions...

If you include a static function in a header file, you much include its body to make the function usable. See the following example, sum1() is static, sum2 is not, notice the code differences. //======= //aa.h #ifndef AA_H #define AA_H int sum2(int a, int b); static int sum1(int a, int b); int sum1(int a, int b) { return a+sum2(b, 10); } #endif //======= //aa.c #include "aa.h" int sum2(int a, int b) { return a+b; } //======= //test.c #include "aa.

Yes. Mapper instance(s) should be setup as a Singleton. For every instance of the DozerBeanMapper, the mapping files are loaded and parsed. You should configure the Mapper as a singleton so that you only incur the cost of loading and initializing the mapping files 1 time. The DozerBeanMapper class is thread safe.

Consider "busy treatments" in telephony, which are features for handling busy situations by performing functions such as forwarding the call to another party, interrupting the callee, retrying the call later, or offering voice mail to the caller. Suppose that we have a feature-description language in which a busy treatment is specified by providing an action, an enabling condition, and a priority. See similar questions...
