- public final class ID3v1Filter
- extends BinaryFilter
- implements org.esau.ptarmigan.impl.RandomAccessFileSource
Extract metadata from an ID3v1 tag
It's a 128-byte block at the end of a file.
May appear on MP3, Ogg, Flac, and other files.
Note that it is unsupported with streams, at least for now. This
is because of the overhead required in scanning to the end of the file.

ID3v1Filter
public ID3v1Filter()
throws org.xml.sax.SAXException
getNamespaceURI
java.lang.String getNamespaceURI()
- Specified by:
getNamespaceURI in class BaseFilter
getNamespacePrefix
java.lang.String getNamespacePrefix()
- Specified by:
getNamespacePrefix in class BaseFilter
doParse
public void doParse()
throws org.xml.sax.SAXException,
java.io.IOException,
java.text.ParseException
- SAX-Invoked parse of a 'document' from an input stream.
Note that the caller must already have called this.getByteStream()
to obtain the raw data for the tag.
This module creates the document from the parsed ID3V1 metadata.
- Specified by:
doParse in class BinaryFilter
writeID3v1
void writeID3v1()
throws java.io.IOException,
org.xml.sax.SAXException,
java.text.ParseException
- build the xml content
getByteStream
java.io.InputStream getByteStream(java.lang.String system_id)
throws java.io.IOException,
org.xml.sax.SAXException
- obtain the id3 tag as a stream of bytes, for handy parsing
Many different filetypes may have an ID3v1 tag (128 bytes)
attached to their end.
- Overrides:
getByteStream in class BaseFilter
maybeWrite
void maybeWrite(byte[] buf,
int length,
java.lang.String xml_name)
throws java.io.IOException,
org.xml.sax.SAXException
