Class RandomActionSequenceGenerator

java.lang.Object
randomGenerators.RandomActionSequenceGenerator
public class RandomActionSequenceGenerator extends Object
The RandomActionSequenceGenerator class is responsible for generating random action sequences based on predefined actions. It utilizes a pseudo-random number generator to select actions from a set of available options and constructs a sequence string.

The class provides the following functionality: Reading the maximum action sequence length from a configuration file. Generating a random action sequence string based on predefined actions.

Usage: Create an instance of RandomActionSequenceGenerator. Call the generateRandomActionSequence() method to generate a random action sequence.

Note: The maximum length of the action sequence is determined by the configuration file. The class uses a pseudo-random number generator to select actions from the available options.

Example: RandomActionSequenceGenerator generator = new RandomActionSequenceGenerator(); String actionSequence = generator.generateRandomActionSequence();

This class is part of the randomGenerators package, which provides utilities for generating random data or sequences in a controlled manner.

  • Constructor Details

    • RandomActionSequenceGenerator

      public RandomActionSequenceGenerator()
      Constructs a RandomActionSequenceGenerator object. It initializes the maximum length of the action sequence from the configuration file.

  • Method Details

    • generateRandomActionSequenceValidCharRandomLength

      public static String generateRandomActionSequenceValidCharRandomLength()
      Generates a random action sequence string based on predefined actions. The length of the action sequence is randomly, but the maximum is determined by the maxLength parameter.
      Returns:
      The generated random action sequence string.

    • generateRandomActionSequence

      public String generateRandomActionSequence()
      Generates a random action sequence string based on predefined actions, with the length of the action sequence is determined by the configuration file.
      Returns:
      The generated random action sequence string.

    • generateAllPossibleCombinations

      public static List<String> generateAllPossibleCombinations (int length, boolean atLeastOneExit, boolean startWithExitCheck)
      Generates a list of all possible combination of the given characters with the inputted length.
      Parameters:
      length - The length of the action sequence.
      atLeastOneExit - If true, the list will contain at least one exit action.
      startWithExitCheck - If true, the list will contain several strings. If an S is present, one of the following characters in the string (that are after an S) will be an E.
      Returns:
      A list of all possible combination of the given characters with the inputted length.

    • generateRandomCombination

      public static String generateRandomCombination (int length, boolean atLeastOneExit, boolean startWithExitCheck)
      The problem with the generateAllPossibleCombinations() method is that when the length is a larger number, the total of possible combinations grows exponentially and the program soon runs out of java heap space. If u do not want all possible combinations, but just a few random ones, this method can help avoiding this problem. It generates a random possible combination.
      Parameters:
      length - The length of the action sequence.
      atLeastOneExit - If true, the string will contain at least one exit action.
      startWithExitCheck - If true, the following will always be true for the result: If an S is present, one of the following characters in the string (that are after an S) will be an E.
      Returns:
      A random possible combination as String.

    • mutateActionSequence

      public static List<String> mutateActionSequence (String actionSequence)
      This method mutates the given action sequence, by replacing each character of the string in turn, with each of the valid characters. It will return a list of all possible mutated action sequences.
      Parameters:
      actionSequence - The action sequence to mutate.
      Returns:
      A list of all possible mutated action sequences.
