wang.bigbird.domain.framework.core.unicode.UnicodeInputStream

所有已实现的接口:

Closeable, AutoCloseable

public class UnicodeInputStream
extends InputStream

This inputstream will recognize unicode BOM marks and will skip bytes if getEncoding() method is called before any of the read(...) methods.

Usage pattern: String enc = "ISO-8859-1"; // or NULL to use systemdefault FileInputStream fis = new FileInputStream(file); UnicodeInputStream uin = new UnicodeInputStream(fis, enc); enc = uin.getEncoding(); // check and skip possible BOM bytes InputStreamReader in; if (enc == null) in = new InputStreamReader(uin); else in = new InputStreamReader(uin, enc);

init

protected void init()
             throws IOException

Read-ahead four bytes and check for BOM marks. Extra bytes are unread back to the stream, only BOM bytes are skipped.

抛出:

IOException

close

           throws IOException

指定者:

close 在接口中 Closeable

指定者:

close 在接口中 AutoCloseable

覆盖:

close 在类中 InputStream

抛出:

IOException

read

public int read()
         throws IOException

指定者:
