Detailed Description

Dictionary is a class like NSDictionary in Obj-C .

Note: Only the pointer of Object or its subclass can be inserted to Dictionary.
// Create a dictionary, return an autorelease object.

Dictionary* pDict = Dictionary::create();

// Insert objects to dictionary

String* pValue1 = String::create("100");

String* pValue2 = String::create("120");

Integer* pValue3 = Integer::create(200);

pDict->setObject(pValue1, "key1");

pDict->setObject(pValue2, "key2");

pDict->setObject(pValue3, "key3");

// Get the object for key

String* pStr1 = static_cast<String*>(pDict->objectForKey("key1"));

log("{ key1: %s }", pStr1->getCString());

Integer* pInteger = static_cast<Integer*>(pDict->objectForKey("key3"));

log("{ key3: %d }", pInteger->getValue());

It returns true if the initializations was successful.

Object* objectForKey ( const std::string & key)

Get the object according to the specified string key.

Note: The dictionary needs to use string as key. If integer is passed, an assert will appear.

// Do something about pStr.

// If you don't know the object type, properly you need to use dynamic_cast<SomeType*> to check it.

if (pStr2 != NULL) {

// Do something about pStr2

}
