包路径：com.oracle.truffle.api.nodes.Node
类名称：Node
方法名：replace

Node.replace介绍

[英]Replaces this node with another node. If there is a source section (see #getSourceSection()) associated with this node, it is transferred to the new node.
[中]将此节点替换为另一个节点。如果存在与此节点关联的源节（请参见#getSourceSection（）），则会将其传输到新节点。
