示例1: removeChild

} else if (parent.getType() == Token.VAR) {
if (parent.hasMoreThanOneChild()) {
parent.removeChild(node);
} else {
// Remove the node from the parent, so it can be reused.
parent.removeChild(node);
// This would leave an empty VAR, remove the VAR itself.
removeChild(parent.getParent(), parent);
}
} else if (node.getType() == Token.BLOCK) {
// Simply empty the block. This maintains source location and
// "synthetic"-ness.
