In computer programming, named parameters, pass-by-name, or keyword arguments refer to a computer language's support for function calls that clearly state the name of each parameter within the function call itself. == Overview == A function call using named parameters differs from a regular function call in that the values are passed by associating each one with a parameter name, instead of providing an ordered list of values. For example, consider the following Java method call that does not use named parameters: window.addNewControl("Title", 20, 50, 100, 50, true); Using named parameters in Objective-C, the call can be written as: (addNewControlWithTitle:@"Title" xPosition:20 yPosition:50 width:100 height:50 drawingNow:YES ); The Objective-C version is more explicit, while the Java version is more concise. Depending on the particular instance, a programmer may find one or the other easier to read. 抄文引用元・出典: フリー百科事典『 ウィキペディア（Wikipedia）』 ■ウィキペディアで「named parameter」の詳細全文を読む スポンサード リンク
