Return Value

An array of building blocks.

Examples

Shows ways of accessing building blocks in a glossary document.

public void GlossaryDocument()
{
    Document doc = new Document();
    GlossaryDocument glossaryDoc = new GlossaryDocument();

    glossaryDoc.AppendChild(new BuildingBlock(glossaryDoc) { Name = "Block 1" });
    glossaryDoc.AppendChild(new BuildingBlock(glossaryDoc) { Name = "Block 2" });
    glossaryDoc.AppendChild(new BuildingBlock(glossaryDoc) { Name = "Block 3" });
    glossaryDoc.AppendChild(new BuildingBlock(glossaryDoc) { Name = "Block 4" });
    glossaryDoc.AppendChild(new BuildingBlock(glossaryDoc) { Name = "Block 5" });

    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
