WITHOUT_ARRAY_WRAPPER option enables you to generate a single object instead of the array. Use this option if you know that you will return single row/object:
SELECT top 3 object_id, name, type, principal_id
FROM sys.objects
WHERE object_id = 3
FOR JSON PATH, WITHOUT_ARRAY_WRAPPER

For some reasons you may want to ignore your build variants. For example: you have 'mock' product flavour and you use it only for debug purposes, such as unit/instrumentation tests.
Let's ignore mockRelease variant from our project. Open build.gradle file and write:

q = Queue.new
q << 1
q << 2
a = Array.new
a << q.pop until q.empty?
Or a one liner:
[].tap { |array| array < queue.pop until queue.empty? }
BackAndroid.addEventListener('hardwareBackPress', function() {
if (!this.onMainScreen()) {
this.goBack();
return true;
}
return false;
});
Note: this.onMainScreen() and this.goBack() are not built in functions, you also need to implement those.

Some procedures have optional arguments. Optional arguments always come after required arguments, but the procedure can be called without them.
For example, if the function, ProcedureName were to have two required arguments (argument1, argument2), and one optional argument, optArgument3, it could b...

Some libraries or plugins may not have typings. Without these, TypeScript can't type check them and therefore causes compilation errors. These libraries can still be used but differently than imported modules.

Both #save and #destroy come wrapped in a transaction that ensures that whatever you do in validations or callbacks will happen under its protected cover. So you can use validations to check for values that the transaction depends on or you can raise exceptions in the callbacks to rollback, includin...

for row in cursor:

The type_traits header contains a set of template classes and helpers to transform and check properties of types at compile-time.
These traits are typically used in templates to check for user errors, support generic programming, and allow for optimizations.
Most type traits are used to c...
Here is a simple JsonArray which you would like to convert to a Java ArrayList:
{
"list": [
"Test_String_1",
"Test_String_2"
]
}
Now pass the JsonArray 'list' to the following method which returns a corresponding...
Sometimes in a development or testing environment, the SSL certificate chain might not have been fully established (yet).
To continue developing and testing, you can turn off SSL verification programmatically by installing an "all-trusting" trust manager:

Emacs uses the terms point, mark, and region to provide more precision about the selected text and position of the cursor. By understanding these terms, it'll help you understand and use other operations and functions.
The point is the place in a buffer where editing (i.e. insertion) is currently t...
A simple example to make a library (rather than an executable, which is the default). TEMPLATE variable specifies type of the project you are making. lib option allows makefile to build a library.

The MPI_Barrier operation performs a synchronization among the processes belonging to the given communicator. That is, all the processes from a given communicator will wait within the MPI_Barrier until all of them are inside, and at that point, they will leave the operation.

Dynamic Arrays
Adding and reducing variables on an array dynamically is a huge advantage for when the information you are treating does not have a set number of variables.
Adding Values Dynamically
You can simply resize the Array with the ReDim Statement, this will resize the array but to if you ...
