public interface EvaluatorProcess

Defines the setup of an evaluator's process. Users can set custom options via setMemory(int) and process-type specific methods. Runtimes can also set options, but should not do so if users have set options by checking isOptionSet().

EvaluatorProcess	setMemory(int megaBytes) Set memory size of process in megabytes.
EvaluatorProcess	setStandardErr(String standardErr) Names a file to which stderr will be redirected.
EvaluatorProcess	setStandardOut(String standardOut) Names a file to which stdout will be redirected.
