Fields Summary

Constructors Summary
public PartOfSet(String identifier, org.jaudiotagger.tag.id3.AbstractTagFrameBody frameBody) Creates a new empty PartOfSet datatype. param identifier identifies the frame type param frameBody super(identifier, frameBody);
public PartOfSet(PartOfSet object) Copy constructor param object super(object);

Methods Summary
public boolean	equals(java.lang.Object obj) if(obj==this) { return true; } if (!(obj instanceof PartOfSet)) { return false; } PartOfSet that = (PartOfSet) obj; return EqualsUtil.areEqual(value, that.value);
protected java.lang.String	getTextEncodingCharSet() Get the text encoding being used. The text encoding is defined by the frame body that the text field belongs to. return the text encoding charset byte textEncoding = this.getBody().getTextEncoding(); String charSetName = TextEncoding.getInstanceOf().getValueForId(textEncoding); logger.finest("text encoding:" + textEncoding + " charset:" + charSetName); return charSetName;
public org.jaudiotagger.tag.datatype.PartOfSet$PartOfSetValue	getValue() return (PartOfSetValue)value;
public void	readByteArray(byte[] arr, int offset) Read a 'n' bytes from buffer into a String where n is the framesize - offset so thefore cannot use this if there are other objects after it because it has no delimiter. Must take into account the text encoding defined in the Encoding Object ID3 Text Frames often allow multiple strings seperated by the null char appropriate for the encoding. param arr this is the buffer for the frame param offset this is where to start reading in the buffer for this field throws NullPointerException throws IndexOutOfBoundsException logger.finest("Reading from array from offset:" + offset); //Get the Specified Decoder String charSetName = getTextEncodingCharSet(); CharsetDecoder decoder = Charset.forName(charSetName).newDecoder(); //Decode sliced inBuffer ByteBuffer inBuffer = ByteBuffer.wrap(arr, offset, arr.length - offset).slice(); CharBuffer outBuffer = CharBuffer.allocate(arr.length - offset); decoder.reset(); CoderResult coderResult = decoder.decode(inBuffer, outBuffer, true); if (coderResult.isError()) { logger.warning("Decoding error:" + coderResult.toString()); } decoder.flush(outBuffer); outBuffer.flip(); //Store value String stringValue = outBuffer.toString(); value = new PartOfSetValue(stringValue); //SetSize, important this is correct for finding the next datatype setSize(arr.length - offset); logger.config("Read SizeTerminatedString:" + value + " size:" + size);
public java.lang.String	toString() return value.toString();
public byte[]	writeByteArray() Write String into byte array It will remove a trailing null terminator if exists if the option RemoveTrailingTerminatorOnWrite has been set. return the data as a byte array in format to write to file String value = getValue().toString(); byte[] data; //Try and write to buffer using the CharSet defined by getTextEncodingCharSet() try { if (TagOptionSingleton.getInstance().isRemoveTrailingTerminatorOnWrite()) { if (value.length() > 0) { if (value.charAt(value.length() - 1) == '\0") { value = value.substring(0, value.length() - 1); } } } String charSetName = getTextEncodingCharSet(); if (charSetName.equals(TextEncoding.CHARSET_UTF_16)) { charSetName = TextEncoding.CHARSET_UTF_16_LE_ENCODING_FORMAT; CharsetEncoder encoder = Charset.forName(charSetName).newEncoder(); //Note remember LE BOM is ff fe but this is handled by encoder Unicode char is fe ff ByteBuffer bb = encoder.encode(CharBuffer.wrap('\ufeff" + value)); data = new byte[bb.limit()]; bb.get(data, 0, bb.limit()); } else { CharsetEncoder encoder = Charset.forName(charSetName).newEncoder(); ByteBuffer bb = encoder.encode(CharBuffer.wrap( value)); data = new byte[bb.limit()]; bb.get(data, 0, bb.limit()); } } //Should never happen so if does throw a RuntimeException catch (CharacterCodingException ce) { logger.severe(ce.getMessage()); throw new RuntimeException(ce); } setSize(data.length); return data;
