Java AWT NativeInterface is an interface for the Java programming language Java programming language that enables Rendering computer graphics rendering library computer science libraries compiled to native code to draw directly to a Java Abstract Window Toolkit AWT Javadoc SE java awt Canvas object computer science object drawing surface. The JavaNativeInterface JNI enabled developers to add platform dependent functionality to Java application software applications . The JNI enables developers to add time critical operations like mathematical calculations and 3D rendering . Previously, native 3D rendering was a problem because the native code didn t have access to the graphic context. The AWT NativeInterface is designed to give developers access to an AWT code Canvas code for direct drawing by native code. In fact, the Java 3D API extension to the standard Java SE JDK relies heavily on the AWT NativeInterface to render 3D objects in Java. The AWT NativeInterface is very similar to the JNI, and, the steps are, in fact, the same as those of the JNI. See the JavaNativeInterface article for an explanation of the JNI techniques employed by the AWT NativeInterface. The AWT NativeInterface was added to the Java platform with the Java Platform, Standard Edition J2SE 1.3 Kestrel version.

An interface in the Java programming language Java programming language is an abstract type that is used to specify an interface computer science interface in the generic sense of the term that class computer science classes must implement. Interfaces are declared using the code interface code Java keywords ... and code Final Java final code . An interface may never contain method definitions. Interfaces cannot be instantiated, but rather are implemented. A class that implements an interface must implement all of the methods described in the interface, or be an abstract class . Object references in Java may be specified to be of an interface type in which case, they must either be null pointer null , or be bound to an object that implements the interface. One benefit of using interfaces is that they simulate multiple inheritance . All classes in Java must have exactly one base class , the only exception being Javadoc SE package java.lang java lang Object the top type root class of the Java type system multiple inheritance of classes is not allowed.

Java Virtual Machine Tool Interface JVMTI, or more properly, JVM TI was introduced in Java Platform, Standard Edition J2SE 5.0 Tiger . This Interface computer science interface allows a computer program program to inspect the state and to control the execution of applications running in the Java Virtual Machine JVM . JVMTI is designed to provide an Application Programming Interface API for the development of tools that need access to the state of the JVM. Examples for such tools are debugger s or profiler computer science profiler s. The JVMTI is a nativeinterface of the JVM. A library, written in C programming language C or C , is loaded during the initialization of the JVM. The library has access to the JVM state by calling JVMTI and JNI JavaNativeInterface functions and can register to receive JVMTI events using event handler functions that are called by the JVM when such an event occurs. JVMTI was defined through the Java Community Process by JSR 163. The JVMTI replaces the JVMPI Java Virtual Machine Profiling Interface and the JVMDI Java Virtual Machine Debug Interface . The JVMPI and the JVMDI are declared as being deprecated in J2SE 5.0 and were removed in Java SE6. JVMTI is the lowest level of the Java Platform Debugger Architecture .

It consists of two distinct packages, Tcl Blend and Jacl. Tcl Blend Tcl Blend is a Tcl extension that makes use of JavaNativeInterface JNI to facilitate communication between a Java interpreter and a Tcl interpreter. Tcl Blend is typically used to load a Java interpreter into an existing Tcl process, so that functionality implemented in Java can be accessed in a Tcl script. For example, one could allocate a Java object in a Tcl script and interactively invoke Java methods on the object. One can also load Tcl Blend and Tcl into a Java process, which adds scripting functionality to an existing Java application. Because Tcl Blend is a normal Tcl extension, one can use it with other popular Tcl extensions like Tk, Expect, and Itcl . Jacl Jacl is a self contained implementation of a Tcl interpreter, written entirely in Java. Jacl also includes features that facilitate communication between a Java interpreter and a Tcl interpreter. Jacl is typically used to incorporate Tcl scripting functionality into an existing Java application, without dealing with the complexities of native code that come with loading Tcl Blend into a Java process.
