Aspose::Words::Markup::SmartTag::Accept method

SmartTag::Accept method

Accepts a visitor.

bool Aspose::Words::Markup::SmartTag::Accept(System::SharedPtr<Aspose::Words::DocumentVisitor> visitor) override

Parameter	Type	Description
visitor	System::SharedPtr<Aspose::Words::DocumentVisitor>	The visitor that will visit the nodes.

ReturnValue

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.

Examples

Shows how to create smart tags.

    // such as a name, date, or address, and converts it to a hyperlink that displays a purple dotted underline.

    // Smart tags are composite nodes that contain their recognized text in its entirety.
    // Add contents to this smart tag manually.

    // Microsoft Word may recognize the above contents as being a date.
    // Smart tags use the "Element" property to reflect the type of data they contain.
