本文整理了Java中org.osgi.framework.Filter类的一些代码示例，展示了Filter类的具体用法。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。Filter类的具体详情如下：
包路径：org.osgi.framework.Filter
类名称：Filter

Filter介绍

[英]An RFC 1960-based Filter.

Filters can be created by calling BundleContext#createFilter(String) or FrameworkUtil#createFilter(String) with a filter string.

A Filter can be used numerous times to determine if the match argument matches the filter string that was used to create the Filter.

Some examples of LDAP filters are:

"(cn=Babs Jensen)" 
"(!(cn=Tim Howes))" 
"(&(" + Constants.OBJECTCLASS + "=Person)(|(sn=Jensen)(cn=Babs J*)))" 
"(o=univ*of*mich*)"

[中]基于RFC 1960的筛选器。
可以通过使用筛选器字符串调用BundleContext#createFilter（字符串）或FrameworkUtil#createFilter（字符串）来创建筛选器。
可以多次使用筛选器来确定match参数是否与用于创建筛选器的筛选器字符串匹配。
LDAP筛选器的一些示例包括：

"(cn=Babs Jensen)" 
"(!(cn=Tim Howes))" 
"(&(" + Constants.OBJECTCLASS + "=Person)(|(sn=Jensen)(cn=Babs J*)))" 
"(o=univ*of*mich*)"
