From b720d0a14601f1496ef15297bc46d401f5a2a890 Mon Sep 17 00:00:00 2001 From: Tom Sepez Date: Mon, 2 Mar 2015 12:18:50 -0800 Subject: Return error information from pdfium to JS. This implements the previously unimplemented JS_Error() function. Along the way: - fix some IWYU when the include order in global.cpp was perturbed. - remove some uses of JS_ErrorString, to increase transparency. - use vp.IsSetting() in place of !vp.IsGetting() for clarity. - specify an error string on several error return paths. - add an error string for writing readonly properties. - rename an error string constant to reflect the actual message. - replace calls to variadic Format() with a function doing string appends. - remove unused JS_GetClassName() R=thestig@chromium.org Review URL: https://codereview.chromium.org/963193003 --- fpdfsdk/include/javascript/JS_Define.h | 58 +++++++++++++++------------------- 1 file changed, 25 insertions(+), 33 deletions(-) (limited to 'fpdfsdk/include/javascript/JS_Define.h') diff --git a/fpdfsdk/include/javascript/JS_Define.h b/fpdfsdk/include/javascript/JS_Define.h index 4246e01964..6edcc97aff 100644 --- a/fpdfsdk/include/javascript/JS_Define.h +++ b/fpdfsdk/include/javascript/JS_Define.h @@ -7,6 +7,9 @@ #ifndef _JS_DEFINE_H_ #define _JS_DEFINE_H_ +#include "../jsapi/fxjs_v8.h" +#include "resource.h" + typedef v8::Value JSValue;
