Remarks

EditableRange is a “facade” object that encapsulates two nodes EditableRangeStart and EditableRangeEnd in a document tree and allows to work with an editable range as a single object.

Examples

Shows how to work with an editable range.

auto doc = MakeObject<Document>();
doc->Protect(ProtectionType::ReadOnly, u"MyPassword");

auto builder = MakeObject<DocumentBuilder>(doc);
builder->Writeln(String(u"Hello world! Since we have set the document's protection level to read-only,") +
                 u" we cannot edit this paragraph without the password.");

// Editable ranges allow us to leave parts of protected documents open for editing.
SharedPtr<EditableRangeStart> editableRangeStart = builder->StartEditableRange();
builder->Writeln(u"This paragraph is inside an editable range, and can be edited.");
SharedPtr<EditableRangeEnd> editableRangeEnd = builder->EndEditableRange();

// A well-formed editable range has a start node, and end node.
// These nodes have matching IDs and encompass editable nodes.
SharedPtr<EditableRange> editableRange = editableRangeStart->get_EditableRange();

ASSERT_EQ(editableRangeStart->get_Id(), editableRange->get_Id());
ASSERT_EQ(editableRangeEnd->get_Id(), editableRange->get_Id());

// Different parts of the editable range link to each other.
ASSERT_EQ(editableRangeStart->get_Id(), editableRange->get_EditableRangeStart()->get_Id());
ASSERT_EQ(editableRangeStart->get_Id(), editableRangeEnd->get_EditableRangeStart()->get_Id());
ASSERT_EQ(editableRange->get_Id(), editableRangeStart->get_EditableRange()->get_Id());
ASSERT_EQ(editableRangeEnd->get_Id(), editableRange->get_EditableRangeEnd()->get_Id());

// We can access the node types of each part like this. The editable range itself is not a node,
// but an entity which consists of a start, an end, and their enclosed contents.
ASSERT_EQ(NodeType::EditableRangeStart, editableRangeStart->get_NodeType());
ASSERT_EQ(NodeType::EditableRangeEnd, editableRangeEnd->get_NodeType());

builder->Writeln(u"This paragraph is outside the editable range, and cannot be edited.");

doc->Save(ArtifactsDir + u"EditableRange.CreateAndRemove.docx");

// Remove an editable range. All the nodes that were inside the range will remain intact.
editableRange->Remove();

Shows how to limit the editing rights of editable ranges to a specific group/user.

                     u" we cannot edit this paragraph without the password.");

    // When we write-protect documents, editable ranges allow us to pick specific areas that users may edit.
    // There are two mutually exclusive ways to narrow down the list of allowed editors.
    // 1 -  Specify a user:
    SharedPtr<EditableRange> editableRange = builder->StartEditableRange()->get_EditableRange();
    editableRange->set_SingleUser(u"[e-mail]");
    builder->Writeln(String::Format(u"This paragraph is inside the first editable range, can only be edited by {0}.", editableRange->get_SingleUser()));
    builder->EndEditableRange();

    ASSERT_EQ(EditorType::Unspecified, editableRange->get_EditorGroup());

    // 2 -  Specify a group that allowed users are associated with:
    editableRange = builder->StartEditableRange()->get_EditableRange();
    editableRange->set_EditorGroup(EditorType::Administrators);
    builder->Writeln(String::Format(u"This paragraph is inside the first editable range, can only be edited by {0}.", editableRange->get_EditorGroup()));
