Java Debug Interface

Package com.sun.jdi

This is the core package of the Java Debug Interface (JDI), it defines mirrors for values, types, and the target VirtualMachine itself - as well bootstrapping facilities.

Exception Summary
AbsentInformationException Thrown to indicate line number or variable information is not available.
ClassNotLoadedException Thrown to indicate that the requested class has not yet been loaded through the appropriate class loader.
ClassNotPreparedException Thrown to indicate that the requested operation cannot be completed because the specified class has not yet been prepared.
IncompatibleThreadStateException Thrown to indicate that the requested operation cannot be completed while the specified thread is in its current state.
InconsistentDebugInfoException Thrown to indicate that there is an inconistency in the debug information provided by the target VM.
InternalException Thrown to indicate that an unexpected internal error has occurred.
InvalidCodeIndexException Deprecated. This exception is no longer thrown
InvalidLineNumberException Deprecated. This exception is no longer thrown
InvalidStackFrameException Thrown to indicate that the requested operation cannot be completed because the specified stack frame is no longer valid.
InvalidTypeException Thrown to indicate a type mismatch in setting the value of a field or variable, or in specifying the return value of a method.
InvocationException Thrown to indicate an exception occurred in an invoked method within the target VM.
NativeMethodException Thrown to indicate an operation cannot be completed because it is not valid for a native method.
ObjectCollectedException Thrown to indicate that the requested operation cannot be completed because the specified object has been garbage collected.
VMCannotBeModifiedException Thrown to indicate that the operation is invalid because it would modify the VM and the VM is read-only.
VMDisconnectedException Unchecked exception thrown to indicate that the requested operation cannot be completed because there is no longer a connection to the target VM.
VMMismatchException Thrown to indicate that the requested operation cannot be completed because the a mirror from one target VM is being combined with a mirror from another target VM.
VMOutOfMemoryException Thrown to indicate that the requested operation cannot be completed because the target VM has run out of memory.
 

Package com.sun.jdi Description

This is the core package of the Java Debug Interface (JDI), it defines mirrors for values, types, and the target VirtualMachine itself - as well bootstrapping facilities. VirtualMachine mirrors the target virtual machine and is the origin of all information provided by the JDI. A VirtualMachine is typically created by using the VirtualMachineManager to create a connection to the target virtual machine (see the com.sun.jdi.connect package). In turn the VirtualMachineManager is typically created by calling Bootstrap.virtualMachineManager().

Most of the methods within this package can throw the unchecked exception VMDisconnectedException.

Methods may be added to the interfaces in the JDI packages in future releases. Existing packages may be renamed if the JDI becomes a standard extension.
