本文整理了Java中javax.jcr.Node.remove()方法的一些代码示例，展示了Node.remove()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.remove()方法的具体详情如下：
包路径：javax.jcr.Node
类名称：Node
方法名：remove

Node.remove介绍

[英]Removes the specified mixin node type from this node and removes mixinName from this node's jcr:mixinTypes property. Both the semantic change in effective node type and the persistence of the change to the jcr:mixinTypes property occur on persist.

If this node does not have the specified mixin, a NoSuchNodeTypeException is thrown either immediately, on dispatch or on persist. Implementations may differ on when this validation is done.

A ConstraintViolationException will be thrown either immediately, on dispatch or on persist, if the removal of a mixin is not allowed. Implementations are free to enforce any policy with regard to mixin removal and may differ on when this validation is done.

A VersionException is thrown either immediately, on dispatch or on persist, if this node is read-only due to a checked-in node. Implementations may differ on when this validation is done.

A LockException is thrown either immediately or on save if a lock prevents the removal of the mixin. Implementations may differ on when this validation is done.
[中]从此节点中删除指定的mixin节点类型，并从此节点的jcr:mixinTypes属性中删除mixinName。有效节点类型的语义更改和jcr:mixinTypes属性更改的持久性都发生在persist上。
如果此节点没有指定的mixin，则在分派或持久化时立即抛出NoSuchNodeTypeException。在完成此验证时，实现可能会有所不同。
如果不允许删除mixin，则ConstraintViolationException将在分派或持久化时立即抛出。实现可以自由执行与mixin删除相关的任何策略，并且在完成此验证时可能会有所不同。
如果此节点由于签入节点而为只读，则在分派或持久化时立即抛出VersionException。在完成此验证时，实现可能会有所不同。
如果锁阻止移除mixin，则会立即或在save上抛出LockException。在完成此验证时，实现可能会有所不同。
