[Exist-development] Scheduler parameters

[Loren C. <lor...@gm...>]

Hello folks,

Currently the passing of parameters into a scheduled task is with strings only.  Currently the parameters are passed in the format of:

    <parameters>
        <param name="param-name1" value="param-value1"/>
    </parameters>

Could we change the format to:

    <parameters>
        <param name="param-name1">param-value1</param>
    </parameters>

or

    <parameters>
        <param>
            <name>param-name1</name>
            <value>param-value1</value>
        </param>
    </parameters>

The current code for processing the parameters is in org.exist.xquery.modules.scheduler.ScheduleFunctions.java  and is:

    private void parseParameters( Node options, Properties properties ) throws XPathException
    {
        if( ( options.getNodeType() == Node.ELEMENT_NODE ) && options.getLocalName().equals( "parameters" ) ) {
            Node child = options.getFirstChild();

            while( child != null ) {

                if( ( child.getNodeType() == Node.ELEMENT_NODE ) && child.getLocalName().equals( "param" ) ) {
                    Element elem  = ( Element )child;
                    String  name  = elem.getAttribute( "name" );
                    String  value = elem.getAttribute( "value" );

                    if( ( name == null ) || ( value == null ) ) {
                        throw( new XPathException( this, "Name or value attribute missing for stylesheet parameter" ) );
                    }
                    properties.setProperty( name, value );
                }
                child = child.getNextSibling();
            }
        }
    }

Can the Quartz scheduler handle the passing of an item() or any other xs:* type as the value in the property?  I am sure that we would have to do a copy of the value that is passed, but is the idea sound?
