本文整理了Java中org.locationtech.geogig.model.Node.getExtraData()方法的一些代码示例，展示了Node.getExtraData()的具体用法。这些代码示例主要来源于Github/Stackoverflow/Maven等平台，是从一些精选项目中提取出来的代码，具有较强的参考意义，能在一定程度帮忙到你。Node.getExtraData()方法的具体详情如下：
包路径：org.locationtech.geogig.model.Node
类名称：Node
方法名：getExtraData

Node.getExtraData介绍

[英]Returns the extra data stored with this node, which shall be considered immutable, regardless of the concrete Map implementation returned.

Changes to the returned map, if it's not immutable, will not affect the internal state of the node.

The returned map may contain null values, but not null key.
[中]返回与此节点一起存储的额外数据，无论返回的具体映射实现如何，这些数据都将被视为不可变的。
对返回的映射的更改（如果不是不变的）不会影响节点的内部状态。
返回的映射可能包含空值，但不包含空键。
