public final class Compiler
extends Object

Deprecated, for removal: This API element is subject to removal in a future version.

JIT compilers and their technologies vary too widely to be controlled effectively by a standardized interface. As such, many JIT compiler implementations ignore this interface, and are instead controllable by implementation-specific mechanisms such as command-line options. This class is subject to removal in a future version of Java SE.

The Compiler class is provided to support Java-to-native-code compilers and related services. By design, the Compiler class does nothing; it serves as a placeholder for a JIT compiler implementation. If no compiler is available, these methods do nothing.

Since:: 1.0
