Examples of com.sun.jdi.LocalVariable

com.sun.jdi.LocalVariable
A local variable in the target VM. Each variable declared within a {@link Method} has its own LocalVariable object. Variables of the samename declared in different scopes have different LocalVariable objects. LocalVariables can be used alone to retrieve static information about their declaration, or can be used in conjunction with a {@link StackFrame} to set and get values. @see StackFrame @see Method @author Robert Field @author Gordon Hirsch @author James McIlree @since 1.3


        //frame arg
        Method method = getUnderlyingMethod(); // onBreak
        //ReferenceType declaringType = method.declaringType(); // org.drools.core.base.mvel.MVELDebugHandler


        LocalVariable var = (LocalVariable) method.variables().get( 0 );//frame


        ClassType frameType = (ClassType) var.type();


        StackFrame frame = getUnderlyingStackFrame();
        Value value = frame.getValue( var );
        //getThread().getTopStackFrame().get
