public abstract class UnaryFunction extends Object implements Expression
UnaryFunction is an abstract class that represents unary arithmetic operations, which are a special kind of Expressions, just like binary operations are.

  • Field Details

    • arg

      public Expression arg
      The expression passed as an argument to the arithmetic operation

    • symbol

      protected String symbol
      The character/string used to represent the arithmetic operation (e.g. "cos")

  • Constructor Details

    • UnaryFunction

      protected UnaryFunction(Expression arg) throws IllegalConstruction
      To construct a unary operation with an expression as argument
      Parameters:
      arg - The expression passed as argument to the arithmetic operation
      Throws:
      IllegalConstruction - Exception thrown if a null argument is passed

  • Method Details

    • getArg

      public Expression getArg()
      getter method to return the argument of an arithmetic operation.
      Returns:
      The argument of the arithmetic operation.

    • getSymbol

      public String getSymbol()
      getter method to return the symbol of the arithmetic operation.
      Returns:
      The symbol of the arithmetic operation.
