示例1: InferResult
private void InferResult(Expression expr, string name, LexicalInfo lexicalInfo, bool useElementType)
{
if (expr == null)
return;
// Prevent creating an infinite number of InferredReturnTypes in inferring cycles
IReturnType returnType;
if (expr.ContainsAnnotation("DomReturnType")) {
returnType = (IReturnType)expr["DomReturnType"];
} else {
returnType = new BooInferredReturnType(expr, resolver.CallingClass);
expr.Annotate("DomReturnType", returnType);
}
if (useElementType)
returnType = new ElementReturnType(resolver.ProjectContent, returnType);
result = new DefaultField.LocalVariableField(returnType, name,
new DomRegion(lexicalInfo.Line, lexicalInfo.Column),
resolver.CallingClass);
}示例2: FindNullableExpressions
private IEnumerable<Expression> FindNullableExpressions(Expression exp)
{
if (exp.ContainsAnnotation("nullableTarget"))
{
yield return ((MemberReferenceExpression) exp).Target;
}
else
{
BinaryExpression bex = exp as BinaryExpression;
if (null != bex)
{
foreach (Expression inner in FindNullableExpressions(bex.Left))
yield return inner;
foreach (Expression inner in FindNullableExpressions(bex.Right))
yield return inner;

{
var be = (BinaryExpression)e;
if (AstUtil.GetBinaryOperatorKind(be) == BinaryOperatorKind.Logical)
return IsConstant(be.Left) && IsConstant(be.Right);
}
if ((e as LiteralExpression) != null
&& !e.ContainsAnnotation(ConstantFolding.FoldedExpression))
return true;
if (IsImplicitCallable(e))
return true;
if (IsConstantInternalField(e.Entity as IField, e))
return true;
