Ease of use— Replaces the Java Native Interface (JNI) with a superior, pure-Java development model. Performance— Provides performance that is comparable to, if not better than, existing APIs such as JNI and sun.misc.Unsafe. Generality— Provides ways to operate on different kinds of foreign...
Per-thread method activation stacks are represented using the host operating system's stack and thread model. Both Java programming language methods and native methods share the same stack, allowing fast calls between the C and Java programming languages. Fully preemptive Java programming language thr...
The aim of the new Java Persistence API is to simplify the development of persistent entities. It meets this objective through a simple POJO-based persistence model, which reduces the number of required classes and interfaces. You model your data using POJOs, and then annotate them to tell the...
类加载器调用了许多Java虚拟机中其他的部分和java.lang包中的很多类。比如,类加载对象就是java.lang.ClassLoader子类 的实例,ClassLoader类中的方法可以访问虚拟机中的类加载机制;每一个被Java虚拟机加载的类都会被表示为一个 java.lang.Class类的实例。像其他对象一样,类加载器对象和Class对象都保存在堆中,被加载...
Navigation Model The JavaServer Faces navigation model makes it easy to define page navigation and to handle any additional processing that is needed to choose the sequence in which pages are loaded. In JavaServer Faces technology,navigationis a set of rules for choosing the next page or view ...
JSR 133, which has been active for nearly three years, has recently issued its public recommendation on what to do about theJavaMemory Model (JMM). InPart 1of this series, columnist Brian Goetz focused on some of the serious flaws that were found in the original JMM, which resulted in so...
The persistent state of an entity can be accessed either through the entity’s instance variables or through JavaBeans-style properties. The fields or properties must be of the following Java language types: Java primitive types java.lang.String ...
If a task is being executed on one node, it acquires a lock which prevents execution of the same task from another node or thread. JSON Libraries for serializing and deserializing JSON to and from Java objects. Avaje Jsonb - Reflection-free Json binding via source code generation with ...
Therefore vmlens uses the Java Memory Model to execute all possible thread interleavings and to check for data races in the program flow.This blog postdescribes how vmlens uses the Java Memory Model to test all thread interleavings. Easy to use ...
When a Java Virtual Machine starts up, there is usually a single non-daemon thread, which typically begins by invoking the methodmainof some designated class. The Java Virtual Machine continues to execute threads according to the thread execution model until all threads that are not daemon threads...
