        public BSHMethod​(java.lang.String bshData,
                 boolean source)
        Creates a BSHMethod.
        Parameters:
        bshData - - May either be the file to source or the script itself to evaluate.
        source - - If true indicates that the bshData passed is a file to source. Otherwise the string itself is evaluated.

      • createBshMethod

        public static BSHMethod createBshMethod​(org.jdom2.Element e)
                                 throws java.io.IOException
        Creates a BSHMethod from a JDom Element. The element is not requiered to have a specific name. If the given element defines an attribute named 'file' the file specified as its value will be sourced by the created BSHMethod. If the 'file' attribute is specified, a 'cache' attribute may be specified as well which can take the values true|false and indicates wether to load the script to memory or to read from the file for every script evaluation. If the 'file' attibute is not specified then the text contained by the element is set to be evaluated by the new BSHMethod. 
          Example 1 : 
          <prepare>
                  import org.jpos.iso.*;
                import org.jpos.transaction.*;

                        msg = context.get("txnRequest");
                        BaseChannel.getChannel("loop-channel").send(msg);
                        result=TransactionConstants.PREPARED | TransactionConstants.READONLY;
                </prepare>

  Example 2 :
          <routing file='cfg\files\routing1.bsh' cache='false'/>
        Throws:
        java.io.IOException
