This class must be implemented by the VM vendor. This class is a placeholder
for environments which explicitly manage the action of a "Just In Time"
compiler.

Object
command
(Object cmd)
Low level interface to the JIT compiler. Can return any object, or null
if no JIT compiler is available.

| Object a command for the JIT compiler
|
Returns
- Object result of executing command
public
static
boolean
compileClass
(Class<?> classToCompile)
Compiles the class using the JIT compiler. Returns true if the
compilation was successful, or false if it failed or there was no JIT
compiler available.
Parameters

| java.lang.Class the class to JIT compile
|
Returns
- boolean indicating compilation success
public
static
boolean
compileClasses
(String nameRoot)

compiler. Returns true if the compilation was successful, or false if it
failed or there was no JIT compiler available.
Parameters
