示例3: writeHeader
import org.apache.lucene.store.DataOutput; //导入方法依赖的package包/类
/**
* Writes a codec header, which records both a string to
* identify the file and a version number. This header can
* be parsed and validated with
* {@link #checkHeader(DataInput, String, int, int) checkHeader()}.
* <p>
* CodecHeader --> Magic,CodecName,Version
* <ul>
* <li>Magic --> {@link DataOutput#writeInt Uint32}. This
* identifies the start of the header. It is always {@value #CODEC_MAGIC}.
* <li>CodecName --> {@link DataOutput#writeString String}. This
* is a string to identify this file.
* <li>Version --> {@link DataOutput#writeInt Uint32}. Records
* the version of the file.
* </ul>
* <p>
* Note that the length of a codec header depends only upon the
* name of the codec, so this length can be computed at any time
* with {@link #headerLength(String)}.
*
* @param out Output stream
* @param codec String to identify this file. It should be simple ASCII,
* less than 128 characters in length.
* @param version Version number
* @throws IOException If there is an I/O error writing to the underlying medium.
