Makoto Kato 70a0912794 Bug 1425547 - Remove unused methods from nsIHTMLInlineTableEditor. r=masayuki
inlineTableEditingEnabled and refreshInlineTableEditingUI are used by
bluegriffon, but other methods aren't used by m-c, c-c and bluegriffon.
So I would like to remove these methods.  Then we can clean up
DoInlineTableEditingAction.

Masayuki Nakano 92d5c4cdd8 Bug 1430785 - Make mozInlineSpellChecker not derived from nsIEditActionListener r=m_kato
mozInlineSpellChecker listens to only DidSplitNode() and DidJoinNodes().
So, EditorBase should call them directly rather than treating it as an
nsIEditActionListener since its runtime cost becomes really cheaper.

Different from EditorSpellCheck, nobody creates instance of
nsIInlineSpellChecker.  So, we can now stop supporting createInstance() for it
in chrome JS and should do this since EditorBase cannot support multiple
mozInlineSpellChecker instances without nsIEditActionListener interface.
Therefore, this patch removes the entry from factory.

Masayuki Nakano 2020349542 Bug 1430982 - part 10: Make EditorBase store TextServicesDocument for its mInlineSpellChecker for avoiding to run for loops to call nsIEditActionListener methods r=m_kato
Currently, first edit action listener is always TextServicesDocument for
EditorBase::mInlineSpellChecker if spell check is enabled and it requires
only DidDeleteNode() and DidJoinNodes().  So, in most cases, EditorBase
should call only them to avoid running redundant for loops for
nsIEditActionListener methods.

This patch makes that EditorBase::AddEditActionListener() and
RemoveEditActionListener() check whether coming nsIEditActionListener is
TextServicesDocument for mInlineSpellChecker.  If so, EditorBase should
store it as reference to TextServicesDocument.  And when edit action occurs,
its DidDeleteNode() and DidJoinNodes() should be called directly.

Unfortunately, this patch makes TextServiceDocument's maintaining rules
complicated.  However, it must be really rare case to add new edit action
listener because it's really old component.

Note that EditorSpellCheck may be created multiple instances for an editor
from chrome JS.  Therefore, we need to keep TextServicesDocument being
derived from nsIEditActionListener because in such case, TextServicesDocument
for other EditorSpellCheck instances should be supported via
nsIEditActionListener even though such case makes EditorBase slower.

Masayuki Nakano 0c82cf40da Bug 1430982 - part 9: Create accessors for each member of mozSpellChecker, EditorSpellCheck, mozInlineSpellChecker r=m_kato
mozSpellChecker stores TextServicesDocument, EditorSpellCheck stores
mozSpellChecker and mozInlineSpellChecker stores EditorSpellCheck.
So, they should have accessors for their member.  Then, EditorBase can
access all of them.

Masayuki Nakano 04e3a3adfc Bug 1430982 - part 8: Make EditorBase store inline spell checker as mozInlineSpellChecker rather than nsIInlineSpellChecker r=m_kato
EditorBase::mInlineSpellChecker is always an instance of mozInlineSpellChecker.
Fortunately, it's easy to expose mozInlineSpellChecker.h.  So, making EditorBase
store it as mozInlineSpellChecker directly, EditorBase can access any of
mozInlineSpellChecker, EditorSpellCheck, mozSpellChecker and
TextServicesDocument with new accessors created by following patch.

created only by nsEditorSpellCheck.  Additionally, mozSpellChecker.h is

directly.

Masayuki Nakano 88c945974e Bug 1430982 - part 1: Make nsTextServicesDocument store editor with RefPtr<TextEditor> rather than nsWeakPtr r=m_kato
nsTextServicesDocument stores editor with nsWeakPtr for avoiding circular
reference.  However, both TextEditor and nsTextServicesDocument are cycle
collectable. So, we don't need to worry about the issue and we can simply
make it store with RefPtr<TextEditor>.  Then, we can make EditorBase and
nsTextServicesDocument access each other directly.

WillDeleteText() and WillDeleteSelection() which are implemented by
FinderHighlighter.  So, we can get rid of the other Will*() from it.

This patch removes a lot of unnecessary virtual calls and copy of strong
pointers to edit action listeners of EditorBase.

Masayuki Nakano 31d493d9fa Bug 1430021 - part 2: Make HTMLEditRules not derived from nsIEditActionListener r=m_kato
HTMLEditRules implements only some of nsIEditActionListener and this is always
first edit action listener.  So, if we make EditorBase treat HTMLEditRules
directly before notifying edit action listeners, we can save a lot of runtime
cost (virtual calls especially unnecessary, copying array of edit action
listeners with strong pointer, redundant QIs), although the code becomes not
beautiful.

Perhaps, we should do same thing to nsTextServicesDocument and
mozInlineSpellChecker in other bugs.

let's move it to an independent header file.

Masayuki Nakano 240d199f53 Bug 1359405 - Redesign HTMLEditor::IsVisTextNode() r=m_kato
Despite of its name, HTMLEditor::IsVisTextNode() returns true with its out
argument when the given text node is empty.  And although it returns nsresult,
it's almost always NS_OK because it returns error only when the editor isn't
usual condition.

So, it should return bool and true when the given text node is visible.

This patch separates the method.  One is for checking the node with frames,
called IsInVisibleTextFrames().  The other is for checking it only with
its text, called IsVisibleTextNode().

Masayuki Nakano 07e48c2f29 Bug 1425412 - part 9: Create factory methods of ChangeAttributeTransaction and remove EditorBase::CreateTxnForSetAttribute() and EditorBase::CreateTxnForRemoveAttribute() r=m_kato
This patch creates two factory methods of ChangeAttributeTransaction.  One is
for setting an attribute to specific value.  The other is for removing an
attribute.  So, EditorBase::CreateTxnForSetAttribute() and
EditorBase::CreateTxnForRemoveAttribute() are unnecessary anymore.

Masayuki Nakano f2369df116 Bug 1425412 - part 8: Create JoinNodeTransaction::MaybeCreate() and remove EditorBase::CreateTxnForJoinNode() r=m_kato
EditorBase::CreateTxnForJoinNode() just hides what it does.
For making the caller clearer, let's create a factory method,
JoinNodeTransaction::MaybeCreate().
