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:
“Neither dead nor alive, the hostage is suspended by an incalculable outcome. It is not his destiny that awaits for him, nor his own death, but anonymous chance, which can only seem to him something absolutely arbitrary.... He is in a state of radical emergency, of virtual extermination.”
—Jean Baudrillard (b. 1929)
“I brush my hair,
waiting in the pain machine for my bones to get hard,
for the soft, soft bones that were laid apart
and were screwed together. They will knit.
And the other corpse, the fractured heart,
I feed it piecemeal, little chalice. I’m good to it.”
—Anne Sexton (1928–1974)
“The study of tools as well as of books should have a place in the public schools. Tools, machinery, and the implements of the farm should be made familiar to every boy, and suitable industrial education should be furnished for every girl.”
—Rutherford Birchard Hayes (1822–1893)
