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

Session.removeItem介绍

[英]Removes the specified item and its subgraph.

This is a session-write method and therefore requires a save in order to dispatch the change.

If a node with same-name siblings is removed, this decrements by one the indices of all the siblings with indices greater than that of the removed node. In other words, a removal compacts the array of same-name siblings and causes the minimal re-numbering required to maintain the original order but leave no gaps in the numbering.

A ReferentialIntegrityException will be thrown on dispatch if the specified item or an item in its subgraph is currently the target of a REFERENCE property located in this workspace but outside the specified item's subgraph and the current Session has read access to that REFERENCE property.

A ConstraintViolationException will be thrown either immediately, on dispatch or on persist, if removing the specified item would violate a node type or implementation-specific constraint. Implementations may differ on when this validation is performed.

A VersionException will be thrown either immediately, on dispatch or on persist, if the parent node of the specified item is read-only due to a checked-in node. Implementations may differ on when this validation is performed.

A LockException will be thrown either immediately, on dispatch or on persist, if a lock prevents the removal of the specified item. Implementations may differ on when this validation is performed.

A PathNotFoundException will be thrown either immediately, on dispatch or on persist, if no accessible item is found at at absPath.

A AccessDeniedException will be thrown either immediately, on dispatch or on persist, if the specified item or an item in its subgraph is currently the target of a REFERENCE property located in this workspace but outside the specified item's subgraph and the current Sessiondoes not have read access to that REFERENCE property.
[中]删除指定的项及其子图。
这是一种会话写入方法，因此需要save才能分派更改。
如果移除同名同级节点，则索引大于移除节点索引的所有同级节点的索引将递减一。换句话说，移除会压缩同名同级的数组，并导致最小的重新编号，以保持原始顺序，但不会在编号中留下任何间隙。
如果指定项或其子图中的项当前是位于此工作区中但在指定项的子图之外的REFERENCE属性的目标，并且当前Session具有对该REFERENCE属性的读取权限，则调度时将抛出ReferentialIntegrityException。
如果删除指定的项会违反节点类型或特定于实现的约束，则ConstraintViolationException将在分派或持久化时立即抛出。执行此验证的时间可能会有所不同。
如果指定项的父节点由于签入节点而为只读，则VersionException将在分派或持久化时立即抛出。执行此验证的时间可能会有所不同。
如果锁阻止删除指定项，则在分派或持久化时会立即抛出LockException。执行此验证的时间可能会有所不同。
如果在[$9$]处找不到可访问的项目，则会在分派或持久化时立即抛出PathNotFoundException。
如果指定的项或其子图中的项当前是位于此工作区中的REFERENCE属性的目标，但位于指定项的子图之外，并且当前Session没有对该REFERENCE属性的读取权限，则AccessDeniedException将在分派或持久化时立即抛出。
