Java Virtual Machine Tool Interface (JVMTI, or more properly, JVM TI) was introduced in J2SE 5.0 (Tiger). This interface allows a 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 debuggers or profilers.
The JVMTI is a native interface of the JVM. A library, written in C or C++, is loaded during the initialization of the JVM. The library has access to the JVM state by calling JVMTI and JNI (Java Native Interface) 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 specification for the Java Platform Profiling Architecture. 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.
Famous quotes containing the words virtual, machine and/or tools:
“Tragedy dramatizes human life as potentiality and fulfillment. Its virtual future, or Destiny, is therefore quite different from that created in comedy. Comic Destiny is Fortune—what the world will bring, and the man will take or miss, encounter or escape; tragic Destiny is what the man brings, and the world will demand of him. That is his Fate.”
—Susanne K. Langer (1895–1985)
“But a man must keep an eye on his servants, if he would not have them rule him. Man is a shrewd inventor, and is ever taking the hint of a new machine from his own structure, adapting some secret of his own anatomy in iron, wood, and leather, to some required function in the work of the world. But it is found that the machine unmans the user. What he gains in making cloth, he loses in general power.”
—Ralph Waldo Emerson (1803–1882)
“Justice and truth are too such subtle points that our tools are too blunt to touch them accurately.”
—Blaise Pascal (1623–1662)
