包路径：org.eclipse.jdt.core.dom.ASTNode
类名称：ASTNode
方法名：setProperty

ASTNode.setProperty介绍

[英]Sets the named property of this node to the given value, or to null to clear it.

Clients should employ property names that are sufficiently unique to avoid inadvertent conflicts with other clients that might also be setting properties on the same node.

Note that modifying a property is not considered a modification to the AST itself. This is to allow clients to decorate existing nodes with their own properties without jeopardizing certain things (like the validity of bindings), which rely on the underlying tree remaining static.
[中]将此节点的命名属性设置为给定值，或设置为null以清除它。
客户端应使用足够唯一的属性名称，以避免与可能也在同一节点上设置属性的其他客户端发生意外冲突。
请注意，修改属性并不视为对AST本身的修改。这是为了允许客户端使用自己的属性来修饰现有节点，而不损害某些依赖于底层树保持静态的东西（如绑定的有效性）。
