示例1: AddSymbolsToContext
private static void AddSymbolsToContext(List<JSSymbol> symbols, mdr.DObject context)
{
//This is called when we are sharing the context, so should be careful not to add fields that are already there
//Technically, this is the generic and safe way to do this.
for (var i = symbols.Count - 1; i >= 0; --i)
{
var symbol = symbols[i];
if (symbol.SymbolType == JSSymbol.SymbolTypes.ClosedOnLocal)
{
var pd = context.Map.GetPropertyDescriptorByFieldId(symbol.FieldId); //TODO: can this be made faster?
if (pd == null)
context.AddOwnPropertyDescriptorByFieldId(symbol.FieldId, PropertyDescriptor.Attributes.Data | PropertyDescriptor.Attributes.NotConfigurable);
}
}
}示例2: CreateArgumentsObject
public static mdr.DArray CreateArgumentsObject(ref mdr.CallFrame callFrame, mdr.DObject context)
{
var metadata = (JSFunctionMetadata)callFrame.Function.Metadata;
Debug.Assert(metadata.Scope.HasArgumentsSymbol, "Invalid situation, created arguments for the wrong scope!");
mdr.DArray arguments = null;
if (metadata.Scope.IsEvalFunction)
{
//Read from context
var tmp = new mdr.DValue();
context.GetField(JSFunctionArguments.Name, ref tmp);
arguments = tmp.AsDArray();
}
else
{
arguments = CreateArgumentsObject(ref callFrame);
var parameters = metadata.FunctionIR.Parameters;
Debug.Assert(arguments.Length >= parameters.Count, "arguments array is not large enough to hold all arguments.");
for (var i = parameters.Count - 1; i >= 0; --i)
{
var symbol = parameters[i].Symbol;
var paramIndex = symbol.ParameterIndex;
Debug.Assert(paramIndex == i, "Invalid situation!, Parameter indexes don't match!");
if (symbol.SymbolType == JSSymbol.SymbolTypes.ClosedOnLocal)
{
var pd = context.AddOwnPropertyDescriptorByFieldId(symbol.FieldId, mdr.PropertyDescriptor.Attributes.Accessor | mdr.PropertyDescriptor.Attributes.NotConfigurable);
context.Fields[pd.Index].Set(new ArgumentAccessor(arguments, paramIndex));
}
}
if (metadata.Scope.HasEval)
context.SetField(JSFunctionArguments.Name, arguments);
}
return arguments;
}示例3: DeclareVariable
public static void DeclareVariable(mdr.DObject context, string field, int fieldId, ref Stack stack)
{
//we may be looking at a global or this might be second time we call this function with the same context, so following assert will fail (incorrectly)
//Debug.Assert(!context.HasOwnPropertyByFieldId(fieldId), "Cannot redeclare local variable {0}", field);
context.AddOwnPropertyDescriptorByFieldId(fieldId, mdr.PropertyDescriptor.Attributes.Data | mdr.PropertyDescriptor.Attributes.NotConfigurable);
