本文整理了Java中org.apache.stanbol.enhancer.servicesapi.Blob类的一些代码示例，展示了Blob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。Blob类的具体详情如下：
包路径：org.apache.stanbol.enhancer.servicesapi.Blob
类名称：Blob

Blob介绍

[英]represents a finite sequence of bytes associated to a mime-type
[中]表示与mime类型关联的有限字节序列

代码示例

/**
 * @param ci
 * @return
 */
private MediaType getMediaType(Blob blob) {
  String[] mediaTypeArray = blob.getMimeType().split("/");
  if(mediaTypeArray.length != 2){
    log.warn("Encounterd illegal formatted mediaType '{}'  -> will try " +
        "to detect the mediaType based on the parsed content!",
      blob.getMimeType());
    return null;
  } else {
    return new MediaType(mediaTypeArray[0], mediaTypeArray[1],
      blob.getParameter());
