public class UnicodeReader
extends java.io.Reader

version: 1.1 / 2007-01-25 - changed BOM recognition ordering (longer boms first) Original pseudocode : Thomas Weidenfeller Implementation tweaked: Aki Nieminen http://www.unicode.org/unicode/faq/utf_bom.html BOMs: 00 00 FE FF = UTF-32, big-endian FF FE 00 00 = UTF-32, little-endian EF BB BF = UTF-8, FE FF = UTF-16, big-endian FF FE = UTF-16, little-endian Win2k Notepad: Unicode format = UTF-16LE http://akini.mbnet.fi/java/unicodereader/ Generic unicode textreader, which will use BOM mark to identify the encoding to be used. If BOM is not found then use a given default or system encoding.

构造器详细资料

UnicodeReader

public UnicodeReader(java.io.InputStream in,
                     java.lang.String defaultEnc)

参数:

in - inputstream to be read

defaultEnc - default encoding if stream does not have BOM marker. Give NULL to use system-level default.

方法详细资料

getDefaultEncoding

public java.lang.String getDefaultEncoding()

getEncoding

public java.lang.String getEncoding()

Get stream encoding or NULL if stream is uninitialized. Call init() or read() method to initialize it.

init

protected void init()
             throws java.io.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:

java.io.IOException

close

public void close()
           throws java.io.IOException

指定者:

close 在接口中 java.io.Closeable

指定者:

close 在接口中 java.lang.AutoCloseable

指定者:

close 在类中 java.io.Reader

抛出:

java.io.IOException

read

public int read(char[] cbuf,
                int off,
                int len)
         throws java.io.IOException

指定者:

read 在类中 java.io.Reader

抛出:

java.io.IOException
