The Reclassify node transforms one set of categorical values
to another. Reclassification is useful for collapsing categories or regrouping data for
analysis.
Example
node = stream.create("reclassify", "My node")
node.setPropertyValue("mode", "Multiple")
node.setPropertyValue("replace_field", True)
node.setPropertyValue("field", "Drug")
node.setPropertyValue("new_name", "Chemical")
node.setPropertyValue("fields", ["Drug", "BP"])
node.setPropertyValue("name_extension", "reclassified")
node.setPropertyValue("add_as", "Prefix")
node.setKeyedPropertyValue("reclassify", "drugA", True)
node.setPropertyValue("use_default", True)
node.setPropertyValue("default", "BrandX")
node.setPropertyValue("pick_list", ["BrandX", "Placebo", "Generic"])
