java - How to auto-detect and wire classes which extends from specific type? -

-

spring supports auto-detect classes using annotation @component , <component-scan>, however, @component not @inherited.

i have tried create custom inheritable annotation:

@component @inherited @retention(runtime) public @interface myinheritablecomponent {}

unfortunately, @myinheritablecomponent doesn't work.

any idea?

edit

file my/package/injectable.java:

@myinheritablecomponent public class injectable {}

file my/package/foo.java:

public class foo extends injectable {}

and component-scan defined as:

<context:component-scan base-package="my.package" />

in above example, foo not auto-detected.

my intention is, hide @component annotation specific classes.

due absence of @inherited on @component <context:component-scan> default filters doesn't respect @inherited on custom annotations.

however, if add custom filter annotation, work expected:

<context:component-scan base-package="my.package">     <context:include-filter type = "annotation" expression = "myinheritablecomponent" /> </context:component-scan>

razor - Is this a bug in WebMatrix PageData? -

i think may have found bug in webmatrix's pagedata, not sure. concerns how pass data partial page calling page. in webmatrix documentation (tutorials, e.g. " 3 - creating consistent look ", , example code), pagedata recommended mechanism pass data between pages (e.g. content page layout page, or partial page). however have found not work other way, pass data partial page calling page. modifying or adding entries in pagedata in partial page, not seem calling page. cutting right down simplest possible example, in test page may have this: @{ pagedata["test"] = "initial entry"; } <p>before calling partial page, test value @pagedata["test"]</p> @renderpage("_testpartial.cshtml") <p>after returning calling page, test value @pagedata["test"]</p> and in _testpartial.cshtml page might have this: @{ pagedata["test"] = "modified entry"; } <p>in partial page...

c# - How to set Z index when using WPF DrawingContext? -

-
how set z-index drawing object when using drawingcontext.drawxxx() methods? the object drawn last have higher z index. can't change index of drawn objects. way draw in order. if using wpf (as placed tag), can use, example, canvas control. create shapes need like polyline obj = new polyline(); //... // ... set properties of obj and add them canvas uielementcollection: yourcanvasname.children.add(obj); //or yourcanvasname.children.insert(i, obj); first items of collection have higher z index. advantages in way: no need redraw on window changes, can anytime move objects , change order.

c# - Cloning WPF controls and object hierarchies -

i have problems cloning object hierarchie. it's toolkit modelling applications, toolbox contains class instances prototypes. i'm having hard time cloning these :) the following code shows problem: public abstract class shape { protected list<uielement> elements; private canvas canvas; ... public canvas getcanvas() { ... }; } public class movableshape : shape { protected ... propertya; private ... propertyxy; ... } public abstract class abstractlayout : movableshape, ... { ... } public class somelayoutclass : abstractlayout, ... { ... } public class acontainingclass { somelayoutclass layout { get; set; } ... } when insert object of acontainingclass project worksheet, should cloned. far tried manual cloning (which fails because of private fields in base classes) , binary serialization ( binaryformatter , memorystreams ). the first approach lacks way call base.clone() method (or wrong?), latter not work because uielement s aren't...
