Class EmgOperationContributor

java.lang.Object

org.eclipse.epsilon.eol.execute.operations.contributors.OperationContributor

org.eclipse.epsilon.emg.execute.operations.contributors.EmgOperationContributor

All Implemented Interfaces:

AutoCloseable, org.apache.commons.math3.random.RandomGenerator, IEmgRandomGenerator<IEmgRandomGenerator.DefaultCharacterSet>

public class EmgOperationContributor
extends OperationContributor
implements IEmgRandomGenerator<IEmgRandomGenerator.DefaultCharacterSet>

The Class ObjectOperationContributor delegates all the random generating functions to a EmgRandomGenerator but overloads the nextXXXList operations to allow the user to specify @list annotations values as listIDs.
