Enum Constant Detail

• AND

  public static final Conjunction AND

  This conjunction is true if and only if all arguments are true.

• OR

  public static final Conjunction OR

  This conjunction is true if and only if at least one argument is true.

• NAND

  public static final Conjunction NAND

  This is the negation of AND. It is only true if at least one argument is false.

• NOR

  public static final Conjunction NOR

  This is the negation of OR. It is only true if all arguments are false .

• XOR

  public static final Conjunction XOR

  This conjunction is true if and only if two arguments differ (exactly one of two arguments if true).

Method Detail

• values

  public static Conjunction[] values()

  Returns an array containing the constants of this enum type, in the order they are declared. This method may be used to iterate over the constants as follows:

  for (Conjunction c : Conjunction.values())
      System.out.println(c);
  

  Returns:

  an array containing the constants of this enum type, in the order they are declared

• valueOf

  public static Conjunction valueOf​(String name)

  Returns the enum constant of this type with the specified name. The string must match exactly an identifier used to declare an enum constant in this type. (Extraneous whitespace characters are not permitted.)

  Parameters:

  name - the name of the enum constant to be returned.

  Returns:

  the enum constant with the specified name

  Throws:

  IllegalArgumentException - if this enum type has no constant with the specified name

  NullPointerException - if the argument is null

• eval

  public boolean eval​(boolean... arguments)

  This method evaluates this conjunction for the given boolean arguments.

  Parameters:

  arguments - are the boolean values to evaluate.

  Returns:

  the result of this conjunction applied to the given arguments.

• evalSingle

  public abstract Boolean evalSingle​(boolean argument)

  Parameters:

  argument - is a literal boolean argument.

  Returns:

  Boolean.TRUE if eval(boolean...) will return true if any of the given arguments has the value of the given argument, Boolean.FALSE if eval(boolean...) will return false if any of the given arguments has the value of the given argument, null otherwise.

• evalEmpty

  public abstract boolean evalEmpty()

  Returns:

  the result of eval(boolean...) for no argument (an empty argument array).

• getSyntax

  public String getSyntax()

  Returns:

  the syntax used for technical representation (e.g. '&&' for AND).

• getName

  public String getName()

  Returns:

  the name and string representation (e.g. "and" for AND).

• negate

  public abstract Conjunction negate()

  Returns:

  the negation of this Conjunction that evaluates to the negated result.

• toString

  public String toString()

  Overrides:

  toString in class Enum<Conjunction>

• ofSymbol

  public static Conjunction ofSymbol​(String symbol)

  Parameters:

  symbol - is the symbol of the requested Conjunction.

  Returns:

  the requested Conjunction or null if no such Conjunction exists.

• ofName

  public static Conjunction ofName​(String name)

  Parameters:

  name - is the name of the requested Conjunction.

  Returns:

  the requested Conjunction or null if no such Conjunction exists.
