Class BeanshellProcessor

java.lang.Object
  org.embl.ebi.escience.scufl.Processor
      org.embl.ebi.escience.scuflworkers.dependency.DependencyProcessor
          org.embl.ebi.escience.scuflworkers.beanshell.BeanshellProcessor

All Implemented Interfaces:

java.io.Serializable, IProcessor

public class BeanshellProcessor
extends DependencyProcessor
implements java.io.Serializable

A processor that uses the Beanshell scripting engine to allow arbitrary java scripts to be invoked on workflow data. In this implementation all inputs and outputs are strings, if this becomes a serious issue I guess we can change it but for now this will do.

Method Detail

getMaximumWorkers

public int getMaximumWorkers()

Description copied from class: Processor

Return the maximum number of task implementations that should be launched for this processor. This is ignored unless the processor is being iterated over in which case a number of threads up to the value specified are created to process the information. You must be particularly careful that the task implementation is thread safe before changing this from the default specified here, at the current time the web service processor is not thread safe!

Specified by:

getMaximumWorkers in interface IProcessor

Overrides:

getMaximumWorkers in class Processor

setScript

public void setScript(java.lang.String theScript)

Set the script

getScript

public java.lang.String getScript()

Get the script

getProperties

public java.util.Properties getProperties()

Get the properties for this processor for display purposes

Specified by:

getProperties in interface IProcessor

Specified by:

getProperties in class Processor

Returns:

a Properties instance containing all processor-specific properties, or optinally null if there are none
