implementation

The @encode directive returns a const char * which is a coded type descriptor of the various elements of the datatype that was passed in. Example follows: struct test { int ti ; char tc ; } ; printf( "%s", @encode(struct test) ) ; // returns "{test=ic}" I could see using sizeof() to determine primitive types - and if it was a full object, I could use the class methods to do introspection. However, How does it determine each element of an opaque struct? @Lothars answer might be "cynical", but it's pretty close to the mark, unfortunately. In order to implement something like @encode() , you need

I created a BlackBerry application using java-me and the BlackBerry specific API. It works fine on the BlackBerry simulator. I want to know how I can deploy this application to a BlackBerry device. From the documentation I found that some code signing is required to run a BlackBerry application on a device. What is this meant for? Do all applications required this code signing? and what are the steps to build my application to run on a BlackBerry device? Dinesh Sharma There are basically two ways to install a Blackberry app on a device: Over The Air (OTA) using Desktop Manager There are

I'm having a hard time refilling the stack after i take it all off in order to print it out. I am using node implementation so i think this fact is what is confusing me. Any suggestions would be appreciated, thank you. This is my original stack::print() // Function to print Gumball info field (color and counter) void Stack::print() { Node *p; Type x; while(top != NULL) { p = top; x = p -> getinfo(); cout << " " << x.color << " " << " " << x.counter << endl << endl; top = p -> getnext(); } return; } This is my stack with my attempt to loop and store in temp. It compiles but still is not working

How to identify library file that contains implementation of native methods ? Ex. public native String intern(); Where can I find implementation (source code) of String.intern() method ? Found answer for String.intern() with quick google search constant pool symbol table cpp : symbol table hpp Yet to find answer for generic way to identify native implementation/library Download this JDK 6 library: http://download.java.net/jdk6/source/ and search through sources. But I think, some code implementations are not accessible as OpenSource There is no general approach to find source code for (any)

I am planning on creating a Node Graph in pyqt. The abstract models that qt provides work for 1D, 2D and Tree data but the abstract class seems to break down for something like a node graph. In particular the "parent" function in QAbstractModel returns QModelIndex of a single parent. In a DAG I will may have multiple parents. One resource I found was this blog post: http://invalidmagic.wordpress.com/2009/12/10/qgraphicsscene-used-as-a-qabstractitemmodel/ It provides some useful information, but I can't seem figure how the model represents the concept of multiple parents. I'm looking for

I have written the following code in C++, however found out that I have to convert it in C. I am not C or even C++ programmer, please help. Can someone help me change this method to C directives, specifically vector implementation, following will not compile I have removed complexity to keep it simple. Thanks in anticipation. __declspec(dllexport) std::vector<MY_STRUCT> WINAPI ABC(char *strVal) { MY_STRUCT f; std::vector<MY_STRUCT> list = std::vector<MY_STRUCT>(); while (*dddd) { /*do the following for every feature in license file*/ f.attrib_num = fi.attrib_num; f.attrib_lic = fi.attrib_lic;
