class VsExpr : public VsStatement

Expression base class:

Inheritance:

Public Methods

virtual VsValue evaluate(VsFunctionCall *)

Evaluates this expression, returning resulting value.

virtual VsStatement::Status1 execute(VsFunctionCall *)

Expressions are also statements, and so must have an execute() method

void ref()

Expressions must be reference counted because variables may be multiply instanced in the parse tree

void unref()

VsExpr()

Constructor, just initializes reference count to zero

Protected Methods

virtual ~VsExpr()

Private Fields

short refCount

Inherited from VsStatement:

Public Classes

enum Status1

Public

enum Status1

VsExpr()

Constructor, just initializes reference count to zero

virtual VsStatement::Status1 execute(VsFunctionCall *)

Expressions are also statements, and so must have an execute() method. The execute() method just calls evaluate() and returns a NORMAL status

virtual VsValue evaluate(VsFunctionCall *)

Evaluates this expression, returning resulting value.

void ref()

Expressions must be reference counted because variables may be multiply instanced in the parse tree

void unref()

virtual ~VsExpr()
