Method Detail

start

public static int start(int threadsNum)

Starts mXparser performance tests. List of performed tests:

• 00. Simple calculations - addition. Expression created once. Iteration: repeatedly recalculated same expression.
• 01. Simple calculations - multiplication. Expression created once. Iteration: repeatedly recalculated same expression.
• 02. Simple calculations - division. Expression created once. Iteration: repeatedly recalculated same expression.
• 03. Simple calculations - power. Expression created once. Iteration: repeatedly recalculated same expression.
• 04. Simple calculations - sinus. Expression created once. Iteration: repeatedly recalculated same expression.
• 05. Simple calculations - 2 additions. Expression created once. Iteration: repeatedly recalculated same expression.
• 06. Simple calculations - 3 additions. Expression created once. Iteration: repeatedlyrecalculated same expression.
• 07. Simple calculations - 3 additions + 1 parenthesis. Expression created once. Iteration: repeatedly recalculated same expression.
• 08. Simple calculations - 3 additions + 2 brackets. Expression created once. Iteration: repeatedly recalculated same expression.
• 09. Simple calculations - 3 additions + 2 brackets. Expression created once. Iteration: repeatedly recalculated same expression.
• 10. Combination of different operations. Expression created once. Iteration: repeatedly recalculated same expression.
• 11. Simple calculations - addition with argument. Expression created once, containing argument 'x'. Iteration: argument value is being modified (increased), then expression is recalculated
• 12. User defined function f(x,y)=3x+4y. Expression Function created once, containing argument 'x'. Iteration: argument value is being modified (increased), then expression is recalculated
• 13. Creating constants: Iteration: Constant c = new Constant("c", 5)
• 14. Creating constants: Iteration: Constant c = new Constant("c=5")
• 15. Creating arguments: Iteration: Argument x = new Argument("x", 5)
• 16. Creating arguments: Iteration: Argument x = new Argument("x=5")
• 17. Creating functions: Iteration: Function f = new Function("f", "x+y", "x", "y")
• 18. Creating functions: Iteration: Function f = new Function("f(x,y)=x+y")
• 19. Creating expressions: Iteration: Expression e = new Expression("sin(2+(3*4)^2)/10")
• 20. Creating expressions + checking syntax: Iteration: Expression e = new Expression("sin(2+(3*4)^2)/10")

Parameters:

threadsNum - Number of threads

Returns:

Number of tests that were not performed.
