java - How to use a lambda expression to pass a method as a parameter when calling another method? -

-

Say I have two ways different from zero fee (integer zodiac, difference account) and Zero ChargeCompany (int sum, int account) . Say I have another method which is called zero processale (string item, customer C) . What can I do, I can either pass in-charge person or chargeToCompany as the argument for the processSale and I can How do I call? 

  if (IG (some customers)) {PROCESSIAL (one item, some customer, charge to individual)} and If (iCompany (some customers)) {processSale (anItem, some customer, charge, customer)}   
 and inside  processSale ()  how will i actually call  chargout person  or  chargeToCustomer () ?   
 
 
 You have two functions:  
  zero charge (Int amount , Int accounts); Zero Incharge Companie (integer amount, int account);   
 What is their likeness that they take both the two  int  parameters and do back  zero . There is no functional interface in  java.util.function  that matches this size but it is easy to define ourselves:  
  interface IntIntConsumer {zero acceptance (Int sum, int accounts); }   
 You can re-type the calling code as follows:  
  if (that is, some person (some customers)) {processSale (anItem, SomeCustomer, MyClass :: chargeToIndividual); } Else if (isCompany (some customers)) {processSale (anItem, SomeCustomer, MyClass :: chargToCompany); } Else {...}   
 Or if  fee-to-Indies  and  in-charge customers  are examples of ways, probably < Code> This :: Chargedondivative  and  This :: Charged customer . Alternatively, the charging function must be stored in a local variable. After this you will have to make a call at  processSale :  
  IntIntConsumer chargeFunc; If (IIG (some customers)) {chargeFunc = it :: Chargedindiv; } Else if (isCompany (some customers)) {chargeFunc = this :: chargeToCompany; } And {...} with the process (one item, some customers, duty functions);   
 The call to the charging function will now look like this:  
  zero process all (item items, customer customer, IntIntConsumer func ) {... func.accept (item.getAmount (), customer.getAccount ()); ...}   
 Of course I have made some assumptions, from where the  amount  and  account  are found, but I think you Can get ideas.

c# - Textbox not clickable but editable -

-
I have a small form with 10 text boxes, I have set them in the correct tab order. I want them on my tab service I was wondering if there is a way to set the text box so that they can be selected for editing until they are tabbed. That is ... I do not want the end user to edit the text box to click on them, I just want to make them editable through tabu. this should do the trick public partial category poor text box: Text Box {Safe Override Zero WndProc (Ref: Message Message) {if (m.msg == (Int) WM.LBUTTONDOWN) {Return; // mount down events} base.WndProc (ref m); }} Window message enum can be found. How to do this without anherizing: text box : class EatMouseDown: netwindows {safe override zero WndProc (ref message message) {if (m.msg == (int) WM.LBUTTONDOWN) {return; } Base.WandProc (Ref M); }} Safe Override Zero Onload (EventEurge E) {base.OnLoad (e); How to do this without any part: left a clean part, whatever is important, this can be a buggy but it works R...

Matlab transpose a table vector -

-
An embarrassing simple question seems to be, but how can I move a Matlab table vector? aTableT = aTable '; I tried a standard syntax for the simple interaction of a line vector to a line vector aTable : ATableT = reshape (aTable, 1, Height (aTable)); and aTableT = rot90 (aTable); According to the head, the last time table should work for table, see. However, I get this error code: Error type in using table / permit (line 396) Undefined function 'permute' for the input arguments. Error in rot 90 (line 29) b = magnitude (b, [2 1 3: ndims (a)]); NB: fliplr is not useful either pretty sure I have covered clear angles - any ideas? Thanks! Try changing your table into an array, move it, then back to a table In other words, try doing this: aTableArray = table2array (aTable); ATableT = array 2table (aTableArray. '); I have also read the document for rot90 , and it says that rot90 is definitely working for tables Do, and I find you...

ios - Adding an SKSpriteNode to SKScene from a child SKSpriteNode -

-
I have a SKScene where I am adding an SKSpriteNode I have subclassed the SKSpriteNode class to create this node. In the subclass I am defining some SKActions on Sprite. What do I want to do when the end of this phantom ends the SKAction sequence, then I add a new Prayer node to this scene. How is this possible. The following code is mine: The code for the sequence is that I'm running on the Scansprinitode subclass (TEMissileNode): - SKAction * moveDown = [SKAction moveToY: Self.position.y - 20 Duration: 0.2]; SKAction * animation = [SKAction animateWithTextures: textures timePerFrame: time / 7]; SKAction * moveMissileProjectile = [SKAction Moving: Pointoffscreen Term: Time]; SKAction * group = [SKAction group: @ [animation, movement projectile]]; SKAction * Sequence = [SKAction Sequence: @ [Hilldown, Group, [SKAction removalFromParent]]]; [Self run action: sequence]; From the main scene, I call those actions that execute these tasks TEMissileNode * missile = [tmissil...
