代码示例

代码示例来源：origin: ydcx/KooReader

public InputStream getInputStream(String entryName) throws IOException {
  return createZipInputStream(getHeader(entryName)); // 取出对应的LocalFileHeader类之后
  // 以此为参数调用ZipFile类的createZipInputStream方法。这个方法带又调用了一个ZipInputStream类的构造函数
}

@Override
public long size() {
  try {
    return getZipFile(myParent).getEntrySize(myName);
  } catch (IOException e) {
    return 0;
  }
}
