The static library is a collection of one or more object files, with an index to allow rapid searching. There are some minor differences in how the compiler deals with them. With an object file you link like this: gcc f1.o f2.o -o myexe with libraries you can also do that: gcc f1.o libf2.a -o … Read more
You could use a deep watcher, but a more elegant solution would be to create computed property of the data you want to watch, and watch that instead: new Vue({ el: ‘#app’, data: () => ({ forms: [{ day: ’12’, month: ‘9’, year: ‘2035’, colors: ‘lightblue’, selected: true }, { day: ’28’, month: ’01’, year: … Read more
You want to get list with only name field? If so, then use map (https://kotlinlang.org/api/latest/jvm/stdlib/kotlin.collections/map.html) val names = list.map { it.name }
For v0.7+ Use fieldnames(x), where x is a DataType. For example, use fieldnames(Date), instead of fieldnames(today()), or else use fieldnames(typeof(today())). This returns Vector{Symbol} listing the field names in order. If a field name is myfield, then to retrieve the values in that field use either getfield(x, :myfield), or the shortcut syntax x.myfield. Another useful and … Read more
The dragging will be a bit more tricky because you need to work out where would the x/y positions of the mouse on the screen (screen space) will be in the 3D world, then you will need to cast a ray and check if it intersects the object you want to drag. I presume this … Read more
IMO, Object storage has nothing to do with scale because someone could build a FS which is capable of storing a huge number of files, even in a single directory. It is also not about the access methods. HTTP access to data in filesystems has been available in many well known NAS systems. Storage/Access by … Read more
Since the objects in Java and C code actually use the same memory locations (the object passed to the native code is the same memory reference in both worlds), a simple if (someJObject == NULL) {} in the C code should be just fine I guess. I haven’t tested it though 🙂
I was using the jackson method, but turns out the performance of this is terrible on Android for first serialization (github issue here). And its dramatically worse for older android versions, (see benchmarks here) But you can do this much faster with Gson. Conversion in both directions shown here: import com.google.gson.Gson import com.google.gson.reflect.TypeToken val gson … Read more
Since the socket is of type Object, you need to convert the object to a string before storing and when retrieving the socket, need to convert it back to an object. You can use JSON.stringify(socket) to convert to a string and JSON.parse(socketstr) to convert back to an object. Edit: Since the release of version 2.0.0, … Read more
If you use the any type instead of Object, you can access any property without compile errors. However, I would advise to create an interface that marks the possible properties for that object: interface Options { selector?: string template?: string } Since all of the fields use ?:, it means that they might or might … Read more
