示例1: Evaluate
public object Evaluate(Token contextToken, List<ExpressionArgument> args, ExecutionState state)
{
object o = state.HasVariable(variableToken.Value) ? state.GetVariable(variableToken.Value) : null;
if (o is IArgumentListEvaluatorExpression)
return ((IArgumentListEvaluatorExpression)o).Evaluate(contextToken, args, state);
else
return SystemTypeEvaluator.EvaluateArguments(state, o, args, contextToken);
}示例2: EvaluateProperty
public object EvaluateProperty(string propertyName, Token token, ExecutionState state)
{
object o = state.HasVariable(variableToken.Value) ? state.GetVariable(variableToken.Value) : null;
if (o is IPropertyEvaluatorExpression)
{
object val = ((IPropertyEvaluatorExpression)o).EvaluateProperty(propertyName, token, state);
if(val != null)
if (val.ToString() == VariableExpression.InvalidProperty)
throw new InstructionExecutionException("\"" + propertyName + "\" is not a valid property of this variable.", token);
return val;
}
else
return SystemTypeEvaluator.EvaluateProperty(o, propertyName, token);
}示例3: Execute
public void Execute(ExecutionState state)
{
IList list;
if (expr is IListExpression)
list = ((IListExpression)expr).GetList(state);
else
{
list = expr.Evaluate(state, listToken) as IList;
if (list == null)
throw new InstructionExecutionException("\"" + listToken.Value + "\" doesn't contain a list of anything.", listToken);
}
if (state.HasVariable(iteratorToken.Value))
throw new InstructionExecutionException("\"" + iteratorToken.Value + "\" already equates to something else. You should use a different word.", iteratorToken);
foreach (object item in list)
{
state.Variables[iteratorToken.Value] = item;
instructions.Execute(state);
}
state.Variables.Remove(iteratorToken.Value);
