Operators

Math Operators:

// Addition
myVar = 5 + 10;		// myVar is 15.

// Subtraction
myVar = 10 - 5;		// myVar is 5.

// Multiplication
myVar = 10 * 5;		// myVar is 50.

// Division
myVar = 10 / 5;		// myVar is 2.

// Plus equals. (myVar currently 10.)
myVar += 5;		// myVar is 15.

// Minus equals. (myVar currently 10.)
myVar -= 5;		// myVar is 5.

// Multiply equals. (myVar currently 10.)
myVar *= 5;		// myVar is 50.

// Divide equals. (myVar currently 10.)
myVar /= 5;		// myVar is 2.

// Plus plus. (myVar currently 10.)
myVar++;		// myVar is 11.

// Minus minus. (myVar currently 10.)
myVar--;		// myVar is 9.

String Concatenation:

// String concatenation uses + operator.
myVar = "Make " + "soap.";		// myVar should be 'Make soap'.

// String + anything else converts the other item to a string.
myVar = "My age is " + 32;		// myVar should be 'My age is 32'.

// Grouping expressions within parenthesis will cause the expression within the
// parenthesis to be evaluated first.
myVar = "My age is " + (20 + 12) + ".";	// myVar should be 'My age is 32.'.

Collection Operators:

// @= is used to append to a list.
myList @= "new value";

// # is the count operator and can be used on maps and lists.
numElements = #myList;

And within the class definition, maps and lists can be assigned starting values using the following syntax.

class myClass {
	public languages = ['c', 'c++', 'java', 'aussom'];
	public myMap = {
		'one' : 1,
		'two' : 2,
		'three' : 3,
		'four' : ['a', 'b', 'c'],
		'five' : { 'make' : 'soap' }
	};

	// ...

	public someFunct() {
		tmp = 'three';
		newmp = {'one': 1, 'two': 2, tmp: 3, 'four': [1, 2, 3, 'tyler'] };
		newmp['five'] = resultOfSomeMethod();
	}
}

Note: Within the class definition member maps and lists can only be defined with primitive types as shown above. When defining members you cannot say call a method and the result be a value in a map.

Callback Operator:

// Double colon operator with a following function name is they proper syntax
// for creating a callback item. They can be stored in variables and passed
// to functions just like other data types.
myCallback = ::someFunction;
