示例1: CosmasCondition
import org.antlr.runtime.tree.Tree; //導入方法依賴的package包/類
public CosmasCondition (Tree cond) {
String nodeString = cond.toStringTree();
if (nodeString.startsWith("-")) {
negated = true;
nodeString = nodeString.substring(1);
}
else if (nodeString.startsWith("+")) {
nodeString = nodeString.substring(1);
}
elem = nodeString.substring(0, 1);
nodeString = nodeString.substring(1);
position = nodeString.equals("a") ? "frames:startswith"
: "frames:endswith";
}
