Example 16 with ImageAddressSpace

use of com.ibm.dtfj.image.ImageAddressSpace in project openj9 by eclipse.

the class Utils method _extractAddressSpace.

// CMVC 175488 : fixed so that this function returns an address space which contains a process
// rather than the first address space it finds.
public static ImageAddressSpace _extractAddressSpace(Image loadedImage) {
    ImageAddressSpace space = null;
    Iterator spaces = loadedImage.getAddressSpaces();
    // object returned through DTFJ iterators
    Object obj = null;
    while (spaces.hasNext()) {
        obj = spaces.next();
        if (obj instanceof ImageAddressSpace) {
            space = (ImageAddressSpace) obj;
