com.sun.jdi.NativeMethodException
- Builds a map of all visible variables, including local variables
and field variables. The returned Map contains both LocalVariable
objects and Field objects, all keyed by their String names. The
map is sorted and so iterating it will return the variables in
alphabetical order.
- Returns:
- map of visible variables in sorted order.
- Throws:
com.sun.jdi.AbsentInformationException
- Thrown if the variable information is missing.com.sun.jdi.InvalidStackFrameException
- Thrown if the stack frame is invalid.com.sun.jdi.NativeMethodException
- Thrown if this method is a native one.
