nested

问题 I am apparently misunderstanding how the C-ish feature of simultaneously "declaring" and referring to a type using struct X works in C++. (Plus I don't even know what this feature is called, properly.) I have three examples below to show what I'm doing but the main question is: Why is the nested type, forward declared in this way, at global scope instead of in class scope? This works to forward declare a nested struct: #include <memory> class Foo1 { Foo1(); ~Foo1(); struct Impl; std::auto_ptr

问题 I am playing with LibGDX and trying to set up a simple board game. public void show() { width = Gdx.graphics.getWidth(); height = Gdx.graphics.getHeight(); viewport = new FitViewport(STAGE_WIDTH, STAGE_HEIGHT); stage = new Stage(viewport); sceneBoard = new GridSceneBoard(10, 30, GridBoardCell.Type.CHECKERED); rootTable = new Table(); rootTable.setFillParent(true); sceneBoard.setFillParent(true); rootTable.add(sceneBoard); stage.addActor(rootTable); Gdx.input.setInputProcessor(stage); } a

问题 I have the following code: listOfStrings = ['i_am_exercising', 'python_functional', 'lists_comprehension'] [ "".join([elem.title() for elem in splited]) for splited in [el.split("_")for el in listOfStrings]] the result of this is: ['IAmExercising', 'PythonFunctional', 'ListsComprehension'] reading the documentation, i got the equivalent extended version, which puts the first expression in a variable to be appended and the second expression in a list to be iterated with the for statement:

问题 I have a situation where I have "nested" toggle statements in jQuery. I have a bunch of selects that allow a user to set a day as open or closed. I then have a select that allows a user to show details about all the days. Details are hidden by default (this is causing my problem). If a user sets a day to closed I don't want to display that day when the user selects to display details for all days. Eg. if monday is set to closed and the rest of the week is open and the user selects "display

问题 I want to create a trigger to validate the date of birth, for example it's not > SYSDATE: Employee -- STRUCTURED TYPE { name VARCHAR2(10) lastname VARCHAR(10) birthdate DATE } Employee_List TABLE OF Employee -- NESTED TABLE Museum -- TABLE { id NUMBER EmployeeList Employee_List } I'm using Oracle 10g. 回答1: You cannot define a trigger like "BEFORE UPDATE ON Museum.EmployeeList.birthdate" But you can write a normal trigger BEFORE UPDATE ON Museum and in trigger body you can loop over all

问题 I am trying to create a few nested classes within my main class. public class MyPlayer : Player { public bool TargetEnemy() { return true; } public class Movement { public uint aInt = 1; public TurnLeft() { } } public class ActionBar { } } I have many different classes so that I would be able to access the MyPlayer class through out the code without passing it to all them I just created a static class that holds the variable for it. I am able to access the MyPlayer->Movement using Main.Units

问题 For what I have read, in some cases it is not possible to nest subqueries in HQL / Hibernate. Let's say that I have a table of articles with a price, that belong to a group. We want to add them all, but we can only add up to a limit per group of articles. Actually, the table is denormalized, so that we already have the maximum amount for the group in the article table. So the SQL would be as simple as : SELECT SUM(case when max_amount is null then price when price<max_amount then price else

问题 Hello I'm trying to match multi-nested quote's blockquotes and transform them back into BBCode This is what I got so far as far as regex is involved Converted it back to html entities to be seen on stackedoverflow <div class="quoteheader"><div class="topslice_quote">([\s\S]*?)</div></div><blockquote>([\s\S]*?)(?:</blockquote><div class="quotefooter"><div class="botslice_quote"></div></div>){2,}) I'm trying to match this <div class="quoteheader"><div class="topslice_quote">Quote</div></div>

问题 So basically i would like to transform code like $my_array = []; $cur_string = ['a', 'b', 'c', 'd']; $v = 'Hello world!'; To something like: $my_array['a']['b']['c']['d'] = $v; I tried something like: foreach( $cur_string as $cur ) { if ( !isset( $current[ $cur ] ) ) { $current[ $cur ] = []; } $current = $current[ $cur ]; } $current[$k] = $v; But I know this code isn't supposed to work.. How can I do this? I don't know exact level of nesting in $cur_string array. 回答1: You can use the
