Example 57 with SuspendedEvent

use of com.oracle.truffle.api.debug.SuspendedEvent in project graal by oracle.

the class DebuggerTesterSnippets method assertLineBreakpointsResolution.

/**
 * Utility method that checks proper resolution of line breakpoints. Breakpoints are submitted
 * to every line of the source and their resolution location is checked.
 * <p>
 * The source need to contain resolution marks in the form of
 * "<code>R&lt;line number&gt;_</code>" where &lt;line number&gt; is line number of the original
 * breakpoint position and <code>R</code> is the resolved mark name. These marks need to be
 * placed at the proper breakpoint resolution line/column position, for a breakpoint submitted
 * to every line. When several submitted breakpoints resolve to the same position, an interval
 * can be specified in the form of
 * "<code>R&lt;line start number&gt;-&lt;line end number&gt;_</code>", where both start and end
 * line numbers are inclusive. The marks are stripped off before execution.
 * <p>
 * The guest language code with marks may look like:
 *
 * <pre>
 * // test
 * function test(n) {
 *   if (R1-3_n &lt;= 1) {
 *     return R4_2 * n;
 *   }
 *   return R5-7_n - 1;
 * }
 * </pre>
 *
 * @param sourceWithMarks a source text, which contains the resolution marks
 * @param resolvedMarkName the mark name. It is used in a regular expression, therefore the mark
 *            must not have a special meaning in a regular expression.
 * @param language the source language
 * @since 0.33
