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

Node.addMixin介绍

[英]Adds the mixin node type named mixinName to this node. If this node is already of type mixinName (either due to a previously added mixin or due to its primary type, through inheritance) then this method has no effect. Otherwise mixinName is added to this node's jcr:mixinTypes property.

Semantically, the new node type may take effect immediately, on dispatch or on persist. The behavior adopted must be the same as the behavior adopted for #setPrimaryType and the behavior that occurs when a node is first created.

A ConstraintViolationException is thrown either immediately, on dispatch or on persist, if a conflict with another assigned mixin or the primary node type or for an implementation-specific reason. Implementations may differ on when this validation is done.

In some implementations it may only be possible to add mixin types before a a node is persisted for the first time. I such cases any later calls to addMixin will throw a ConstraintViolationException either immediately, on dispatch or on persist.

A NoSuchNodeTypeException is thrown either immediately, on dispatch or on persist, if the specified mixinName is not recognized. Implementations 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, on dispatch or on persist, if a lock prevents the addition of the mixin. Implementations may differ on when this validation is done.
[中]将名为mixinName的mixin节点类型添加到此节点。如果此节点已经是mixinName类型（由于先前添加的mixin或由于其主类型，通过继承），则此方法无效。否则，mixinName将添加到此节点的jcr:mixinTypes属性。
从语义上讲，新节点类型可能会在分派或持久化时立即生效。所采用的行为必须与#setPrimaryType所采用的行为以及首次创建节点时发生的行为相同。
如果与另一个指定的mixin或主节点类型发生冲突，或者由于特定于实现的原因，在分派或持久化时立即抛出ConstraintViolationException。在完成此验证时，实现可能会有所不同。
在某些实现中，可能只有在第一次持久化节点之前才能添加mixin类型。我认为，在这种情况下，以后任何对addMixin的呼叫都会立即抛出ConstraintViolationException，无论是在发送时还是在持续时。
如果指定的mixinName无法识别，则NoSuchNodeTypeException会在分派或持久化时立即抛出。在完成此验证时，实现可能会有所不同。
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。
如果锁阻止添加mixin，则LockException会在分派时或持久化时立即抛出。在完成此验证时，实现可能会有所不同。
