+// User got to this page by clicking a link on another page. |
+PAGE_TRANSITION(LINK, 0) |
+ |
+// User got this page by typing the URL in the URL bar. This should not be |
+// used for cases where the user selected a choice that didn't look at all |
+// like a URL; see GENERATED below. |
+// |
+// We also use this for other "explicit" navigation actions. |
+PAGE_TRANSITION(TYPED, 1) |
+ |
+// User got to this page through a suggestion in the UI, for example) |
+// through the destinations page. |
+PAGE_TRANSITION(AUTO_BOOKMARK, 2) |
+ |
+// This is a subframe navigation. This is any content that is automatically |
+// loaded in a non-toplevel frame. For example, if a page consists of |
+// several frames containing ads, those ad URLs will have this transition |
+// type. The user may not even realize the content in these pages is a |
+// separate frame, so may not care about the URL (see MANUAL below). |
+PAGE_TRANSITION(AUTO_SUBFRAME, 3) |
+ |
+// For subframe navigations that are explicitly requested by the user and |
+// generate new navigation entries in the back/forward list. These are |
+// probably more important than frames that were automatically loaded in |
+// the background because the user probably cares about the fact that this |
+// link was loaded. |
+PAGE_TRANSITION(MANUAL_SUBFRAME, 4) |
+ |
+// User got to this page by typing in the URL bar and selecting an entry |
+// that did not look like a URL. For example, a match might have the URL |
+// of a Google search result page, but appear like "Search Google for ...". |
+// These are not quite the same as TYPED navigations because the user |
+// didn't type or see the destination URL. |
+// See also KEYWORD. |
+PAGE_TRANSITION(GENERATED, 5) |
+ |
+// This is a toplevel navigation. This is any content that is automatically |
+// loaded in a toplevel frame. For example, opening a tab to show the ASH |
+// screen saver, opening the devtools window, opening the NTP after the safe |
+// browsing warning, opening web-based dialog boxes are examples of |
+// AUTO_TOPLEVEL navigations. |
+PAGE_TRANSITION(AUTO_TOPLEVEL, 6) |
+ |
+// The user filled out values in a form and submitted it. NOTE that in |
+// some situations submitting a form does not result in this transition |
+// type. This can happen if the form uses script to submit the contents. |
+PAGE_TRANSITION(FORM_SUBMIT, 7) |
+ |
+// The user "reloaded" the page, either by hitting the reload button or by |
+// hitting enter in the address bar. NOTE: This is distinct from the |
+// concept of whether a particular load uses "reload semantics" (i.e. |
+// bypasses cached data). For this reason, lots of code needs to pass |
+// around the concept of whether a load should be treated as a "reload" |
+// separately from their tracking of this transition type, which is mainly |
+// used for proper scoring for consumers who care about how frequently a |
+// user typed/visited a particular URL. |
+// |
+// SessionRestore and undo tab close use this transition type too. |
+PAGE_TRANSITION(RELOAD, 8) |
+ |
+// The url was generated from a replaceable keyword other than the default |
+// search provider. If the user types a keyword (which also applies to |
+// tab-to-search) in the omnibox this qualifier is applied to the transition |
+// type of the generated url. TemplateURLModel then may generate an |
+// additional visit with a transition type of KEYWORD_GENERATED against the |
+// url 'http://' + keyword. For example, if you do a tab-to-search against |
+// wikipedia the generated url has a transition qualifer of KEYWORD, and |
+// TemplateURLModel generates a visit for 'wikipedia.org' with a transition |
+// type of KEYWORD_GENERATED. |
+PAGE_TRANSITION(KEYWORD, 9) |
+ |
+// Corresponds to a visit generated for a keyword. See description of |
+// KEYWORD for more details. |
+PAGE_TRANSITION(KEYWORD_GENERATED, 10) |
+ |
+// ADDING NEW CORE VALUE? Be sure to update the LAST_CORE and CORE_MASK |
+// values below. Also update CoreTransitionString(). |
+PAGE_TRANSITION(LAST_CORE, PAGE_TRANSITION_KEYWORD_GENERATED) |
+PAGE_TRANSITION(CORE_MASK, 0xFF) |
+ |
+// Qualifiers |
+// Any of the core values above can be augmented by one or more qualifiers. |
+// These qualifiers further define the transition. |
+ |
+// User used the Forward or Back button to navigate among browsing history. |
+PAGE_TRANSITION(FORWARD_BACK, 0x01000000) |
+ |
+// User used the address bar to trigger this navigation. |
+PAGE_TRANSITION(FROM_ADDRESS_BAR, 0x02000000) |
+ |
+// User is navigating to the home page. |
+PAGE_TRANSITION(HOME_PAGE, 0x04000000) |
+ |
+// The beginning of a navigation chain. |
+PAGE_TRANSITION(CHAIN_START, 0x10000000) |
+ |
+// The last transition in a redirect chain. |
+PAGE_TRANSITION(CHAIN_END, 0x20000000) |
+ |
+// Redirects caused by JavaScript or a meta refresh tag on the page. |
+PAGE_TRANSITION(CLIENT_REDIRECT, 0x40000000) |
+ |
+// Redirects sent from the server by HTTP headers. It might be nice to |
+// break this out into 2 types in the future, permanent or temporary, if we |
+// can get that information from WebKit. |
+PAGE_TRANSITION(SERVER_REDIRECT, 0x80000000) |
+ |
+// Used to test whether a transition involves a redirect. |
+PAGE_TRANSITION(IS_REDIRECT_MASK, 0xC0000000) |
+ |
+// General mask defining the bits used for the qualifiers. |
