If FindField returns -1, the Field could not be found in the Fields collection. Developers working with SDE should be aware of qualified field names and their impact on calls to FindField. For more information, see the IFields2 interface. ...
AJavainterfaceis a bit like aJava class, except a Java interface can only contain method signatures and fields. A Java interface is not intended to contain implementations of the methods, only the signature (name, parameters and exceptions) of the method. However, it is possible to provide de...

An Interface in JAVA is able to achieve 100% abstraction as it only contains those methods which has no implementation (i.e. methods without body). In other words we can say interface can only contain method signature and fields. Starting JAVA 8 default and static methods can have implementat...
Creates a common parent− As with the EventListener interface, which is extended by dozens of other interfaces in the Java API, you can use a tagging interface to create a common parent among a group of interfaces. For example, when an interface extends EventListener, the JVM knows that ...
JVMTI (JVM Tool Interface)是Java虚拟机对外提供的Native编程接口,通过JVMTI,外部进程可以获取到运行时JVM的诸多信息,比如线程、GC等。Agent是一个运行在目标JVM的特定程序,它的职责是负责从目标JVM中获取数据,然后将数据传递给外部进程。加载Agent的时机可以是目标JVM启动之时,也可以是在目标JVM运行时进行加载,而在...
We can create multi-module projects comprised of a “main application” and several library modules. 我们可以创建”一个主程序应用“和多个库模块形成的多模块项目。 和Maven的多Moudule概念类似,只不过是语言本身开始支持这种封包方式。 We have to be careful though because we can only have one module pe...
Map<Field,Value> getValues(List<? extendsField> fields) Returns a map containing theValueof each staticFieldin the given list. The Fields must be valid for this type; that is, they must be declared in this type, a superclass, a superinterface, or an implemented interface. ...

The JNI interface is organized like a C++ virtual function table or a COM interface. The advantage to using an interface table, rather than hard-wired function entries, is that the JNI name space becomes separate from the native code. A VM can easily provide multiple versions of JNI function...
