Example 6 with ClosingFileReader

use of com.ibm.dtfj.corereaders.ClosingFileReader in project openj9 by eclipse.

the class Builder method openFile.

public ClosingFileReader openFile(String filename) throws IOException {
    // this is where the resolving agent comes in handy.  Not only will it look on the filesystem but it is also free to look into jars and other interesting containers where we can expect to find things
    File foundFile = _resolvingAgent.findFileWithFullPath(filename);
    ClosingFileReader reader = new ClosingFileReader(foundFile);
    _fileTracker.addFile(reader);
    return reader;
}
