Class Definitions

Classes are declared using the class keyword. It may have any of the usual access modifiers. The Superclass inheritance and Interface conformance are indicated with the inherits and implements keywords.

Interfaces are declared in much the same way except the keyword is interface and method and property bodies are not defined. Interface hierarchies (SuperInterfaces?) can also be specified using inherits

Instance variables are declared within the class using keyword var.

    var <variableName> [ as <Type>] [ is <AccessModifiers>]
    var _<variableName> [as <Type>]

    var x as String
    var _y as int
    var z as int is private

_ prefix - private ( and directly accessable in methods) without prefix - public (by default ) override using is syntax access using .

class variable access modifier shared as in is shared

  • how initialize??



accessing baseclass methods

==Example ==

interface Audible
    def makesNoise as String

interface Mateable
    pro mateName as String

interface Breedable
    inherits Mateable 

    pro childName as String

# class declaration - note indentation
class Bovidae
    def diet as String
        return 'Herbivorous Cud Chewing'
    def nHooves as String
        return 'four'

class Sheep 
    is public, nonvirtual    # public is default anyway
    inherits Bovidae        # Superclass
    implements Audible, Breedable
    var _lifeSpan as int is shared      # years average
     # or var lifeSpan as int private shared

    var _age as int =1
    var liveWeight as int is private
    var _isAlive as bool
	#	_lifespan = 8  
    def init
        _age = 1
        .liveWeight = 2
		_isAlive = true

    def makesNoise as String
        return 'Baaaaa'

    pro mateName as String
			return 'Ram'
    pro childName as String
			return 'lamb'

    def age( byNYears as int)
        _age += byNYears
        if _age > _lifeSpan
            _isAlive = false

	def gainWgt( wgt as int)
		.liveWeight += wgt

    def toString as String is new
        return 'Sheep:age=[_age], wgt=[.liveWeight], living=[_isAlive]'
    def main is shared
	s = Sheep()
	print 's=[s.toString]'
