Class VMProxyArg

VMProxyArg

public VMProxyArg(NVelocity.Runtime.RuntimeServices rs,
                  string contextRef,
                  string callerRef,
                  int t)

ctor for current impl * takes the reference literal we are proxying for, the literal the VM we are for is called with... *

Parameters:

contextRef - reference arg in the definition of the VM, used in the VM

callerRef - reference used by the caller as an arg to the VM

t - type of arg : JJTREFERENCE, JJTTRUE, etc

VMProxyArg

public VMProxyArg(NVelocity.Runtime.Directive.VMProxyArg model,
                  NVelocity.Context.InternalContextAdapter c)

not used in current impl * Constructor for alternate impl where VelProxy class would make new VMProxyArg objects, and use this contructor to avoid reparsing the reference args * that impl also had the VMProxyArg carry it's context

CallerReference

public string CallerReference

ContextReference

public string ContextReference

NodeTree

public NVelocity.Runtime.Parser.Node.SimpleNode NodeTree

StaticObject

public object StaticObject

Type

public int Type

getObject

public object getObject(NVelocity.Context.InternalContextAdapter context)

returns the value of the reference. Generally, this is only called for dynamic proxies, as the static ones should have been stored in the VMContext's localcontext store *

Parameters:

context - Context to use for getting current value

Returns:

Object value *

isConstant

public bool isConstant()

tells if arg we are poxying for is dynamic or constant. *

Returns:

true of constant, false otherwise

setObject

public object setObject(NVelocity.Context.InternalContextAdapter context,
                        object o)

Invoked by VMContext when Context.put() is called for a proxied reference. *

Parameters:

context - context to modify via direct placement, or AST.setValue()

o - new value of reference

Returns:

Object currently null
