Component-Based Programming

Type safetyType safety

Automatic memory managementAutomatic memory management

This greatly simplifies application This greatly simplifies application developmentdevelopment

Type Safety

Type safety ensures that objects are used Type safety ensures that objects are used the way they were intended to be usedthe way they were intended to be used

Prevents an object’s state from being corruptedPrevents an object’s state from being corrupted

The CLR enforces type safetyThe CLR enforces type safetyAttempting to coerce an object to an Attempting to coerce an object to an incompatible type causes the CLR to throw an incompatible type causes the CLR to throw an exceptionexception

Type safety means code confidenceType safety means code confidenceCommon programmer errors will be found Common programmer errors will be found immediatelyimmediatelyRectangle(hwnd, 0, 0, 10, 10);Rectangle(hwnd, 0, 0, 10, 10);

//hwnd should be an hdc//hwnd should be an hdc

MessageBox(hwnd, “”, “”, IDOK);MessageBox(hwnd, “”, “”, IDOK);

//IDOK should be MB_OK//IDOK should be MB_OK

Automatic Memory Management

The CLR tracks the code’s use of objects and The CLR tracks the code’s use of objects and ensuresensures

Objects are not freed while still in use (no memory Objects are not freed while still in use (no memory corruption)corruption)

Objects are freed when no longer in use (no memory leaks)Objects are freed when no longer in use (no memory leaks)

Code is easier to write because there is no question Code is easier to write because there is no question as to which component is responsible to free an as to which component is responsible to free an objectobject

When passed a buffer, who frees it: caller or callee?When passed a buffer, who frees it: caller or callee?

Each process has 1 heap used by all componentsEach process has 1 heap used by all componentsObjects can’t be allocated from different heapsObjects can’t be allocated from different heaps

You don’t have to know which heap memory was allocated You don’t have to know which heap memory was allocated in or which API to call to free the memoryin or which API to call to free the memory
