Aspose::Words::Border::GetHashCode method

Border::GetHashCode method

Serves as a hash function for this type.

int32_t Aspose::Words::Border::GetHashCode() const override

Examples

Shows how border collections can share elements.

auto doc = MakeObject<Document>();
auto builder = MakeObject<DocumentBuilder>(doc);

builder->Writeln(u"Paragraph 1.");
builder->Write(u"Paragraph 2.");

// Since we used the same border configuration while creating
// these paragraphs, their border collections share the same elements.
SharedPtr<BorderCollection> firstParagraphBorders = doc->get_FirstSection()->get_Body()->get_FirstParagraph()->get_ParagraphFormat()->get_Borders();
SharedPtr<BorderCollection> secondParagraphBorders = builder->get_CurrentParagraph()->get_ParagraphFormat()->get_Borders();

for (int i = 0; i < firstParagraphBorders->get_Count(); i++)
{
    ASSERT_TRUE(System::ObjectExt::Equals(firstParagraphBorders->idx_get(i), secondParagraphBorders->idx_get(i)));
    ASSERT_EQ(System::ObjectExt::GetHashCode(firstParagraphBorders->idx_get(i)), System::ObjectExt::GetHashCode(secondParagraphBorders->idx_get(i)));
    ASSERT_FALSE(firstParagraphBorders->idx_get(i)->get_IsVisible());
}

for (const auto& border : System::IterateOver(secondParagraphBorders))
{
    border->set_LineStyle(LineStyle::DotDash);
}

// After changing the line style of the borders in just the second paragraph,
// the border collections no longer share the same elements.
for (int i = 0; i < firstParagraphBorders->get_Count(); i++)
{
    ASSERT_FALSE(System::ObjectExt::Equals(firstParagraphBorders->idx_get(i), secondParagraphBorders->idx_get(i)));
    ASSERT_NE(System::ObjectExt::GetHashCode(firstParagraphBorders->idx_get(i)), System::ObjectExt::GetHashCode(secondParagraphBorders->idx_get(i)));

    // Changing the appearance of an empty border makes it visible.
    ASSERT_TRUE(secondParagraphBorders->idx_get(i)->get_IsVisible());
}

doc->Save(ArtifactsDir + u"Border.SharedElements.docx");
