Constructor Summary

HostScriptProvider()
Creates a new instance of AsyncXMLDocumentProvider

Method Summary

java.lang.String	getDefaultArgs() If the provider has a set of default arguments, they can be retrieved with this function.
java.lang.String	getDescription() Returns a description of the provider's functionality.
java.lang.String	getErrorString() The provider should return a string representation of the current error, if any
java.lang.String	getName() Returns the display name of the provider.
int	getState() Retrieve the current state
static void	main(java.lang.String[] args)
void	output(java.io.OutputStream outStream)
protected void	parseArgs(java.lang.String args)
void	run()
void	run(java.lang.String args, java.io.OutputStream outStream) Triggers the execution of the provider, updating the provider's internal state and sending the output to the specified OutputStream.
void	run(java.lang.String args, java.lang.String callbackName, ServiceDataProviderDocumentCallback callback, java.lang.Object context) Triggers the asynchronous execution of the provider, sending the output to the specified callback Object.
void	setSampleFile(java.lang.String fileName)
void	setSampleRefresh(long millis)
void	terminate() Signals the provider to shutdown, cease data callbacks and free any associated resources
void	update(java.lang.String argStr) this should perform a one-off query of the provider, but it probably won't work properly as we need to have started up most of the async stuff.
