From a02082397a4e012b925a0f9ffff86ee54259812a Mon Sep 17 00:00:00 2001 From: sornaks Date: Wed, 8 Jul 2015 18:03:19 -0700 Subject: [PATCH] Introducing IHtmlContent in Mvc.Razor. - Changing HtmlHelper and HelperResult to implement IHtmlContent. - Introducing BufferedHtmlContent. - Making RazorPage handle only IHtmlContent and clearing out other types. - Making StringCollectionTextWriter use BufferedHtmlContent so that it can be returned where necessary. - Updating places which involve Write/Copy to pass in encoders. - The encoders are currently not being used during write. But when HtmlString is modified to carry encode metadata, the encoder can be used for writing. This is a perf optimization and hence not a part of this change. - Making TagHelperContent implement IHtmlContent. --- .../HelperResult.cs | 12 +- src/Microsoft.AspNet.Mvc.Razor/RazorPage.cs | 50 +++---- .../RazorTextWriter.cs | 11 +- .../TagHelperContentExtensions.cs | 4 +- .../Rendering/BufferedHtmlContent.cs | 113 ++++++++++++++++ .../Rendering/Html/HtmlHelper.cs | 6 +- .../Rendering/HtmlHelperPartialExtensions.cs | 15 ++- .../Rendering/HtmlString.cs | 45 +++---- .../Rendering/IHtmlHelper.cs | 3 +- .../Rendering/StringCollectionTextWriter.cs | 64 ++++----- .../project.json | 2 +- .../IBufferedTextWriter.cs | 4 +- .../RazorPageTest.cs | 14 +- .../RazorTextWriterTest.cs | 41 +++--- .../Rendering/BufferedHtmlContentTest.cs | 127 ++++++++++++++++++ .../Rendering/DefaultEditorTemplatesTest.cs | 3 +- .../HtmlHelperPartialExtensionsTest.cs | 15 ++- .../Rendering/HtmlStringTest.cs | 65 +++++++++ .../StringCollectionTextWriterTest.cs | 25 ++-- 19 files changed, 450 insertions(+), 169 deletions(-) create mode 100644 src/Microsoft.AspNet.Mvc.ViewFeatures/Rendering/BufferedHtmlContent.cs create mode 100644 test/Microsoft.AspNet.Mvc.ViewFeatures.Test/Rendering/BufferedHtmlContentTest.cs create mode 100644 test/Microsoft.AspNet.Mvc.ViewFeatures.Test/Rendering/HtmlStringTest.cs diff --git a/src/Microsoft.AspNet.Mvc.Razor/HelperResult.cs b/src/Microsoft.AspNet.Mvc.Razor/HelperResult.cs index 138345467b..3055cc0523 100644 --- a/src/Microsoft.AspNet.Mvc.Razor/HelperResult.cs +++ b/src/Microsoft.AspNet.Mvc.Razor/HelperResult.cs @@ -3,28 +3,31 @@ using System;
