Class UnicodeInputStream

java.lang.Object

java.io.InputStream

de.hybris.bootstrap.xml.UnicodeInputStream

All Implemented Interfaces:

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. Invoking read methods without first calling getEncoding will not skip BOM mark. Usage pattern: String enc = "ISO-8859-1"; // or put NULL to use systemdefault FileInputStream fis = new FileInputStream(file); UnicodeInputStream uin = new UnicodeInputStream(fis, enc); enc = uin.getEncoding(); // check for BOM mark and skip bytes InputStreamReader in; if (enc == null) in = new InputStreamReader(uin); else in = new InputStreamReader(uin, enc);

isBOMSkipped

public boolean isBOMSkipped()

setSkipBOM

public void setSkipBOM(boolean b)

getDefaultEncoding

public String getDefaultEncoding()

getEncoding

public String getEncoding()

Read encoding based on BOM mark and skip bytes. All non-mark bytes are unread back to the stream.

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.
