Adobe Air Native Extension (ANE) for EJDB
EJDB for iOS, Mac OS X, and Windows on Adobe AIR. EJDB is a fast MongoDB-like library for document database storage and querying embedded into your application.
// Open the zoo DB
var db:EJDBDatabase = EJDB.open("zoo", EJDB.DEFAULT_OPEN_MODE | EJDB.JBOTRUNC) as EJDBDatabase;
var parrot1:Object = {
"name" : "Grenny",
"type" : "African Grey",
"male" : true,
"age" : 1,
"birthdate" : new Date(),
"likes" : ["green color", "night", "toys"],
"extra1" : null
};
var parrot2:Object = {
"name" : "Bounty",
"type" : "Cockatoo",
"male" : false,
"age" : 15,
"birthdate" : new Date(),
"likes" : ["sugar cane"]
};
var oids:Array = db.save("parrots", [parrot1, parrot2]);
trace("Grenny OID: " + parrot1._id);
trace("Bounty OID: " + parrot2._id);
var cursor:EJDBCursor = db.find("parrots",
{"likes" : "toys"},
[],
{"$orderby" : {"name" : 1}}
);
trace("Found " + cursor.length + " parrots");
while (cursor.next()) {
trace(cursor.field("name") + " likes toys!");
}
cursor.close(); // It IS mandatory to close cursor explicitly to free up resources
db.close(); // Close the databaseDatabase files are memory mapped and limited to 2GB on all 32bit platforms. This applies to all supported platforms in the ANE since Adobe only supports 32bit extensions.
The native extension is using ruby's rake for it's build system and therefore requires ruby 1.9.3, this is installed by default on OS X Lion. Additionally, you must have Xcode and the iOS SDK's installed on your system.
To build simply type rake build into your terminal from within the root directory of the native extension. If this is your first time building the build system will generate the file config/build.yml and prompt you to edit the file for your system. The relevant changes are the path to your Adobe Air SDK and what version of the iOS SDK you are using.
After editing your config/build.yml file, simply type rake build again. If all goes well you will see the airejdb.ane file sitting in your bin directory.
Since this is a multiplatform ANE, building is a bit more complicated then usual. If you are running on Mac OS X you will find a file called ejdb-build.sh in the config directory. Before executing the rake script you will want to run this script via sh ejdb-build.sh to generate the Mac and iOS universal binaries of ejdb, as well as download the windows libraries of ejdb.
You will then need to find a way to build the windows MSVC solution found in platforms/windows/AirEJDB.sln, I personally use Visual C++ Express 2010 via Parallels running Windows 7. After compiling the MSVC solution, the rake script will compile the iOS and Mac native libraries, then package all available platforms.
