Method Summary

java.util.Map<java.lang.String,DataThing>	execute(java.util.Map inputMap) Given a Map of DataThing objects as input, invoke the underlying logic of the task and return a map of DataThing objects as outputs, with the port names acting as keys in the map in both cases.
java.lang.String[]	inputNames() Get an array of the names of input ports for this processor
java.lang.String[]	inputTypes() Get an array of the string types for the inputs defined by the inputNames() method, these should probably use the constants defined in this interface but may use any valid Baclava data type specifier.
java.lang.String[]	outputNames() Names of the output ports
java.lang.String[]	outputTypes() Types of the output ports
