TagChunk

@uml Represents a placeholder tag in a tree pattern. A tag can have any of the following forms.

<ul> <li>{@code expr}: An unlabeled placeholder for a parser rule {@code expr}.</li> <li>{@code ID}: An unlabeled placeholder for a token of type {@code ID}.</li> <li>{@code e:expr}: A labeled placeholder for a parser rule {@code expr}.</li> <li>{@code id:ID}: A labeled placeholder for a token of type {@code ID}.</li> </ul>

This class does not perform any validation on the tag or label names aside from ensuring that the tag is a non-null, non-empty string.

class TagChunk : Chunk {

this(string tag);

this(string label, string tag);

string getTag();

string getLabel();

string toString();

}
