The following tables summarize the semantic similarities between Java and VjO.
Semantic | Java | VJET VJO |
---|---|---|
Declare a Namespace | package vjo.x.y | vjo.ctype("vjo.x.y.Z") // where Z is the name of a class. |
Import a Class | import vjo.utils.X | .needs("vjo.utils.X") |
Type Definitions and Manipulation
Semantic | Java | VJET VJO |
---|---|---|
Define a Class | class X{} |
vjo.ctype("<namespace>.X") |
Define an Interface | interface Y{} |
vjo.itype("<namespace>.Y") |
Define an Enum | enum E{} |
vjo.etype("<namespace>.E") |
Define an Abstract Class | abstract class Z{} |
//> abstract vjo.ctype("<namespace>.Z") |
Define an Inner Class | class X{} |
X : vjo.ctype() |
Modify a Type | final class R{}; |
//> final vjo.ctype("vjo.R") |
Define a Constructor | D(){} |
constructs: function(){} |
Overload a Constructor | D(int arg){} D(String arg){} |
//>public void constructs(int arg) //>public void constructs(String arg) constructs:function(arg){} |
Call a Super Constructor | super() |
this.base() |
Call a Super Constructor with Arguments | super(arg) |
this.base(arg) |
Call a Super Method | super.doIt() |
this.base.doIt() |
Extend a Class | class X extends Y |
vjo.ctype("<namespace>.X") .inherits("<namespace>.Y") |
Implement an Interface | class X implements Y |
vjo.ctype("<namespace>.X") .satisfies("<namespace>.Y") |
Implement an Instance Method | void setName(String name) |
.protos({ setName: function(String name) |
Implement a Static Method | static void setName(String name) |
.props({ setName: function(String name) }) |
Implement a Static Initializer | {// static initialization here static{...} |
// static initialization here .inits(function(){...}) |
test
Declarations
To Declare | Java | VJET VJO |
---|---|---|
Enum Constants |
public enum Days { MON,TUE,WED,THU,FRI,SAT,SUN }
|
vjo.etype('<namespace>.Days') .values('MON,TUE,WED,THU,FRI,SAT,SUN')
|- | Argument Types
void setName(String name){}
|
//> void setName(String name) setName : function(name){}
|- | Method Scope
public void setName(String name){}
|
//>public void setName(String name) setName : function(name){}
|- | Return Type
public X getIt(){}
|
//> public X getIt() getIt : function(){}
|- | Overloaded Method |
public X getIt(String x) public X getIt(int x)
//>public X getIt(String x) //>public X getIt(int x) getIt:function(x) {}
|- | Method with Variable Arguments |
public X getIt(String... x)
//>public X getIt(String... x) getIt:function(x) {}
|- | Local Variable |
int x = 10; String s = "hello"; final boolean ok = false;
|
var x = 10; //< int var s = 'hello'; //< String var ok = false; //< final boolean
