Method Detail
-
vm
protected abstract VirtualMachine vm() throws ExecutionControl.EngineTerminationException
Returns the JDIVirtualMachineinstance.- Returns:
- the virtual machine
- Throws:
ExecutionControl.EngineTerminationException- if the VM is dead/disconnected
-
redefine
public void redefine(ExecutionControl.ClassBytecodes[] cbcs) throws ExecutionControl.ClassInstallException, ExecutionControl.EngineTerminationException
Redefine the specified classes. Where 'redefine' is, as in JDI and JVMTI, an in-place replacement of the classes (preserving class identity) -- that is, existing references to the class do not need to be recompiled. This implementation uses JDIVirtualMachine.redefineClasses(java.util.Map). It will be unsuccessful if the signature of the class has changed (see the JDI spec). The JShell-core is designed to adapt to unsuccessful redefine.- Specified by:
redefinein interfaceExecutionControl- Parameters:
cbcs- the class name and bytecodes to redefine- Throws:
ExecutionControl.ClassInstallException- exception occurred redefining the classes, some or all were not redefinedExecutionControl.EngineTerminationException- the execution engine has terminated
-
referenceType
protected ReferenceType referenceType(VirtualMachine vm, String name)
Returns the JDIReferenceTypecorresponding to the specified class name.- Parameters:
vm- the current JDIVirtualMachineas returned byvm()name- the class name to look-up- Returns:
- the corresponding
ReferenceType
