Example 1 with HeapDumpFormatter

use of com.ibm.jvm.dtfjview.heapdump.HeapDumpFormatter in project openj9 by eclipse.

the class HeapdumpCommand method dumpMultipleHeapsInSeparateFiles.

private void dumpMultipleHeapsInSeparateFiles(JavaRuntime runtime, String version, boolean is64Bit, boolean phdFormat, String baseFileName, Set heapsToDump) throws IOException {
    Iterator heapIterator = runtime.getHeaps();
    HeapDumpFormatter formatter = null;
    while (heapIterator.hasNext()) {
        Object thisHeapObj = heapIterator.next();
        if (thisHeapObj instanceof CorruptData) {
            out.println("Heap corrupted at: " + ((CorruptData) thisHeapObj).getAddress());
            _numberOfErrors++;
            continue;
        }
        JavaHeap thisHeap = (JavaHeap) thisHeapObj;
        // Create a new heapdump formatter for every heap we find
        if (formatter != null) {
            formatter.close();
        }
        if (heapsToDump.size() > 0 && !heapsToDump.contains(thisHeap.getName())) {
            continue;
        }
        String fileName = getFileNameForHeap(thisHeap, baseFileName);
        out.print("Writing " + (phdFormat ? "PHD" : "Classic") + " format heapdump for heap " + thisHeap.getName() + " into " + fileName + "\n");
        formatter = getFormatter(fileName, version, is64Bit, phdFormat);
        // We have to dump classes in every heapdump
        dumpClasses(formatter, runtime);
        dumpHeap(formatter, thisHeap);
    }
    if (formatter != null) {
        formatter.close();
