simple objects

IntroducedIntent: Define an interface that creates an object, letting its subclasses decide which factory class to instantiate, and the factory pattern to defer its creation to subclasses.Main Solution: The main solution to the problem of interface

The localization of data is divided into two main aspects: 1. Local persistence of simple data (NSString, Nsarray, Nsdictionary, NSData) 2. Local persistence of complex data (this article takes the person class as an example)Localization of Simple

Interface can be configured to read and write configuration files, VCL provides a way to save the interface resources TReader and Twriter way.Object Form1:tform1 Left = 0 Top = 0 Caption = ' Form1 ' ... Object Lbl1:tlabel Left = Top = 152

Vectors allocate a contiguous address space for stored objects, so random access to the elements in the vector is highly efficient. Inserting or deleting an element in Vecotor requires that an existing element be copied and moved. If the objects

Simple objects such as nsstring,nsnumber,nsarray,nsdictionary can be conveniently stored in local sandbox files, and complex objects, such as properties and methods, require the use of archive anti-archiving methods (serialization and

One way to "make something happen" is to evaluate an expression with a side effect. Injected assignments and function calls these expressions with side-effects can be used as separate statements, and this expression is also called an expression

Builder pattern uses multiple simple objects to build a complex object step-by-step. This type of design pattern belongs to the Create pattern, which provides an optimal way to create an object.A Builder class constructs the final object
