Aspose::Words::BuildingBlocks::BuildingBlockCollection::ToArray method

BuildingBlockCollection::ToArray method

Copies all building blocks from the collection to a new array of building blocks.

System::ArrayPtr<System::SharedPtr<Aspose::Words::BuildingBlocks::BuildingBlock>> Aspose::Words::BuildingBlocks::BuildingBlockCollection::ToArray()

ReturnValue

An array of building blocks.

Examples

Shows ways of accessing building blocks in a glossary document.

void GlossaryDocument_()
{
    auto doc = MakeObject<Document>();
    auto glossaryDoc = MakeObject<GlossaryDocument>();

    for (int i = 1; i <= 5; ++i)

        block->set_Name(String(u"Block ") + System::Convert::ToString(i));
        glossaryDoc->AppendChild(block);
    }
    ASSERT_EQ(5, glossaryDoc->get_BuildingBlocks()->get_Count());

    doc->set_GlossaryDocument(glossaryDoc);

    // There are various ways of accessing building blocks.
    // 1 -  Get the first/last building blocks in the collection:
    ASSERT_EQ(u"Block 1", glossaryDoc->get_FirstBuildingBlock()->get_Name());
    ASSERT_EQ(u"Block 5", glossaryDoc->get_LastBuildingBlock()->get_Name());

    // 2 -  Get a building block by index:
    ASSERT_EQ(u"Block 2", glossaryDoc->get_BuildingBlocks()->idx_get(1)->get_Name());
    ASSERT_EQ(u"Block 3", glossaryDoc->get_BuildingBlocks()->ToArray()->idx_get(2)->get_Name());

    // 3 -  Get the first building block that matches a gallery, name and category:
    ASSERT_EQ(u"Block 4", glossaryDoc->GetBuildingBlock(BuildingBlockGallery::All, u"(Empty Category)", u"Block 4")->get_Name());

    // We will do that using a custom visitor,
    // which will give every BuildingBlock in the GlossaryDocument a unique GUID
    auto visitor = MakeObject<ExBuildingBlocks::GlossaryDocVisitor>();
    glossaryDoc->Accept(visitor);
