QUESTION
For consistency I'm specifying return types since PHP 7.1, for all methods, including magic ones like __toString
, and even when the implicit return type is void
like with __unserialize()
:
ANSWER
Answered 2020-May-23 at 09:43The concept of Constructors
and Destructors
was introduced in PHP5
. They do not return anything explicitly. They do not have any return type. As the definition of Constructor goes, it is used in the creation of an object that is an instance of a class. It is used to initialize an object of the class as the constructor declaration looks just like a method declaration that has no result type. Implicitly, they return the current instance of the class.

I have a JavaFX application which contains a SwingNode with an OpenGL app in it. Most of the time, everything is fine, but sometimes when I close the window I get this error:

Answered 2020-Jan-09 at 15:56i am not sure but you are doing Platform.exit() that force Application.lauch() to return so you should put System.exit() in the main() function, because JavaFX runtime close when you do Platform.exit() and stop() method is called but in the same time System.exit() is called

QUESTION
I recently (three days ago) began coding in c and i cannot understand why the final scanf is breaking my code.
I checked the syntax and from what i can tell it is correct. I revised the final segment to multiply integers instead of doubles, and it worked. I revised the final segment to multiply floats instead of doubles, and it broke.
...ANSWER
Answered 2019-Aug-07 at 04:52Your Problem
The issue roots from that you are using %f to write into a double
instead of a float. Thus to fix the issue you can either change you format specifier to lf
or change the data type of your variables to float

QUESTION
TL:DR:
I need to find the most efficient Cypher query that would get the nodes connected to a certain node type with a certain type of relation and to then retrieve the connections between those nodes, filter out the top 150 most connected ones, and show them to the user.
I propose one below using APOC relationships property query, but I think it can be made more efficient, so I'm looking for your advice.
LONG EXPLANATION:
In my datamodel I have the nodes of the type:
:Concept
:Context
:User
:Statement
This is used for text network analysis, so the basic idea is that the :Concepts
appear in :Statements
that belong to a certain :Context
added by a certain :User
.
They also have properties, such as uid
(the unique ID), and name
(the name).
Every :Concept
is connected to every other :Concept
with the :TO
type of directed relation.
If a :Concept
belongs to a :Context
it has the :AT
relation to that :Context
If a :Concept
is made by a :User
it is connected to that user with the :BY
type of relation.
I also added properties to relations, so that they show which user made the :TO
connection and in which context they appeared.
I need to get a list of nodes and their relationships in a certain context, so I currently use the Cypher / APOC query of the type:
...ANSWER
Answered 2019-Jan-02 at 01:41You're generating a cartesian product of those :Concept nodes which is slowing down your query.
You could try this instead:

QUESTION
The history of PHP says that the older versions of PHP use the class name as a method for a constructor for the same class.
The PHP 5.3.3 documentation says that:
Methods with the same name as the last element of a namespaced class name will no longer be treated as constructor. This change doesn't affect non-namespaced classes.
Example:
...ANSWER
Answered 2018-May-08 at 05:30Regarding why this rule applies for namespaced classes
vs. non-namespaced
, PHP 5.3
introduced namespaces. If you were upgrading from an older PHP
version, you would have non-namespaced classes to look after, potentially using the old style way of creating constructors.
They want to enforce that you are developing within modern PHP
principles and that you are also using the new conventions. PHP
at this point is committed to removing old-style constructors completely, which we have seen as they are deprecated in PHP 7
and will be removed in a future version.
Finally, the reasoning behind dropping this convention altogether is that it is more error-prone. Using the DRY principles, if one was to change a class name while refactoring, forgetting to change the name of the constructor, it could have subtle and not-so-subtle repercussions.
If you are extending a class and want to call its constructor, it is also more error-prone if their parent class's name changes. For further reading:
