示例1: testIndexDeletionPolicy
# 需要导入模块: from org.apache.lucene.index import DirectoryReader [as 别名]
# 或者: from org.apache.lucene.index.DirectoryReader import listCommits [as 别名]
def testIndexDeletionPolicy(self):
writer = self.getWriter()
# no commits exist in the index yet
self.assertTrue(self.policy.onInitCalled)
# we haven't called commit yet
self.assertFalse(self.policy.onCommitCalled)
doc = Document()
writer.addDocument(doc)
writer.commit()
# now we called commit
self.assertTrue(self.policy.onCommitCalled)
# external IR sees 1 commit:
self.assertEquals(1, DirectoryReader.listCommits(self.directory).size())
# commit again:
writer.addDocument(doc)
writer.commit()
# external IR sees 2 commits:
self.assertEquals(2, DirectoryReader.listCommits(self.directory).size())
writer.close()
# open same index, make sure both commits survived:
writer = self.getWriter()
self.assertTrue(self.policy.onInitCalled)
self.assertFalse(self.policy.onCommitCalled)
self.assertEquals(2, DirectoryReader.listCommits(self.directory).size())
writer.close()
# 3 from closing writer again
self.assertEquals(3, DirectoryReader.listCommits(self.directory).size())
