Example 22 with Breakpoint

use of org.eclipse.che.api.debug.shared.model.Breakpoint in project che by eclipse.

the class JavaDebugger method getValue.

/**
     * Get value of variable with specified path. Each item in path is name of variable.
     * <p>
     * Path must be specified according to the following rules:
     * <ol>
     * <li>If need to get field of this object of current frame then first element in array always should be
     * 'this'.</li>
     * <li>If need to get static field in current frame then first element in array always should be 'static'.</li>
     * <li>If need to get local variable in current frame then first element should be the name of local variable.</li>
     * </ol>
     * </p>
     * Here is example. <br/>
     * Assume we have next hierarchy of classes and breakpoint set in line: <i>// breakpoint</i>:
     * <pre>
     *    class A {
     *       private String str;
     *       ...
     *    }
     *
     *    class B {
     *       private A a;
     *       ....
     *
     *       void method() {
     *          A var = new A();
     *          var.setStr(...);
     *          a = var;
     *          // breakpoint
     *       }
     *    }
     * </pre>
     * There are two ways to access variable <i>str</i> in class <i>A</i>:
     * <ol>
     * <li>Through field <i>a</i> in class <i>B</i>: ['this', 'a', 'str']</li>
     * <li>Through local variable <i>var</i> in method <i>B.method()</i>: ['var', 'str']</li>
     * </ol>
     *
     * @param variablePath
     *         path to variable
     * @return variable or <code>null</code> if variable not found
     * @throws DebuggerException
     *         when any other errors occur when try to access the variable
