      • getProperties

        public edu.uiuc.ncsa.security.core.configuration.XProperties getProperties()
        These properties are for external systems that must manage when or how the scripts are run. For instance, if there is a version of the script. QDL does not care what version the author has of this, but it must be preserved. These are set and managed externally -- QDL itself never touches these or cares about them.

      • setProperties

      • setInputStream

        public void setInputStream​(InputStream inputStream)

      • getInputStream

        public InputStream getInputStream()
        In the case of actual files, the reader will be set to a Reader. In other cases (such as from a zip file or collection of lines in a memory VFS) about the best we can do is return a reader for iterating. Note that you should get this once and use it until you close it. This is because there are no well defined ways in Java to check if a generic InputStream has been closed without trying something (like reading some bytes) and seeing if it throws an exception. Therefore, this will take the backing set of lines and return a new byte array output stream every time.
