]GlossaryDocument.Accept method
Accepts a visitor.
public override bool Accept(DocumentVisitor visitor)
Parameter | Type | Description |
---|---|---|
visitor | DocumentVisitor | The visitor that will visit the nodes. |
Return Value
True if all nodes were visited; false if DocumentVisitor
stopped the operation before visiting all nodes.
Remarks
Enumerates over this node and all of its children. Each node calls a corresponding method on DocumentVisitor
.
For more info see the Visitor design pattern.
Calls VisitGlossaryDocumentStart
, then calls Accept
for all child nodes of this node and then calls VisitGlossaryDocumentEnd
at the end.
Note: A glossary document node and its children are not visited when you execute a Visitor over a Document
. If you want to execute a Visitor over a glossary document, you need to call Accept
.
Examples
Shows ways of accessing building blocks in a glossary document.
public void GlossaryDocument()
{
Document doc = new Document();
GlossaryDocument glossaryDoc = new GlossaryDocument();
BuildingBlock child1 = new BuildingBlock(glossaryDoc) { Name = "Block 1" };
glossaryDoc.AppendChild(child1);
BuildingBlock child2 = new BuildingBlock(glossaryDoc) { Name = "Block 2" };
glossaryDoc.AppendChild(child2);
BuildingBlock child3 = new BuildingBlock(glossaryDoc) { Name = "Block 3" };
glossaryDoc.AppendChild(child3);
BuildingBlock child4 = new BuildingBlock(glossaryDoc) { Name = "Block 4" };
glossaryDoc.AppendChild(child4);
BuildingBlock child5 = new BuildingBlock(glossaryDoc) { Name = "Block 5" };
glossaryDoc.AppendChild(child5);
Assert.AreEqual(5, glossaryDoc.BuildingBlocks.Count);
doc.GlossaryDocument = glossaryDoc;
// There are various ways of accessing building blocks.
// 1 - Get the first/last building blocks in the collection:
Assert.AreEqual("Block 1", glossaryDoc.FirstBuildingBlock.Name);
Assert.AreEqual("Block 5", glossaryDoc.LastBuildingBlock.Name);
// 2 - Get a building block by index:
Assert.AreEqual("Block 2", glossaryDoc.BuildingBlocks[1].Name);
Assert.AreEqual("Block 3", glossaryDoc.BuildingBlocks.ToArray()[2].Name);
// 3 - Get the first building block that matches a gallery, name and category:
Assert.AreEqual("Block 4",
glossaryDoc.GetBuildingBlock(BuildingBlockGallery.All, "(Empty Category)", "Block 4").Name);
// We will do that using a custom visitor,
// which will give every BuildingBlock in the GlossaryDocument a unique GUID
GlossaryDocVisitor visitor = new GlossaryDocVisitor();
// Visit start/end of the Glossary document.
glossaryDoc.Accept(visitor);
// Visit only start of the Glossary document.
glossaryDoc.AcceptStart(visitor);
// Visit only end of the Glossary document.
glossaryDoc.AcceptEnd(visitor);
Console.WriteLine(visitor.GetText());
// In Microsoft Word, we can access the building blocks via "Insert" -> "Quick Parts" -> "Building Blocks Organizer".
doc.Save(ArtifactsDir + "BuildingBlocks.GlossaryDocument.dotx");
