本文整理了Java中com.google.cloud.storage.Blob.delete()方法的一些代码示例，展示了Blob.delete()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。Blob.delete()方法的具体详情如下：
包路径：com.google.cloud.storage.Blob
类名称：Blob
方法名：delete

Blob.delete介绍

[英]Deletes this blob.

Example of deleting the blob, if its generation matches the Blob#getGeneration()value, otherwise a StorageException is thrown.

boolean deleted = blob.delete(BlobSourceOption.generationMatch());else  
// the blob was not found 
} 
}

[中]删除此blob。
删除blob的示例，如果其生成与blob#getGeneration（）值匹配，则抛出StorageException。

boolean deleted = blob.delete(BlobSourceOption.generationMatch());else  
// the blob was not found 
} 
}

代码示例

 */
// [TARGET delete(BlobSourceOption...)]
public boolean delete() {
 // [START delete]
 boolean deleted = blob.delete(BlobSourceOption.generationMatch());

  // the blob was deleted
 } else {
  // the blob was not found
 }
 // [END delete]
 return deleted;
