invalidate back to summary

invalidate	back to summary
public void invalidate(boolean deoptimize) Invalidates this installed code such that any subsequent invocation will throw an `InvalidInstalledCodeException`. If this installed code is already invalid, this method has no effect. A subsequent call to `isAlive()` or `isValid()` on this object will return `false`. Parameters deoptimize:boolean if `true`, all existing invocations will be immediately deoptimized. If `false`, any existing invocation will continue until it completes or there is a subsequent call to this method with `deoptimize == true` before the invocation completes.

public void invalidate(boolean deoptimize)

Invalidates this installed code such that any subsequent invocation will throw an InvalidInstalledCodeException. If this installed code is already invalid, this method has no effect. A subsequent call to isAlive() or isValid() on this object will return false.

Parameters

deoptimize:boolean: if true, all existing invocations will be immediately deoptimized. If false, any existing invocation will continue until it completes or there is a subsequent call to this method with deoptimize == true before the invocation completes.

isAlive	back to summary
public boolean isAlive() Returns:boolean true if this object still points to installed code

isValid	back to summary
public boolean isValid() Returns:boolean true if the code represented by this object is still valid for invocation, false otherwise (may happen due to deopt, etc.)
