public class PartOfSet
extends AbstractString

Represents the form 01/10 whereby the second part is optional. This is used by frame such as TRCK and TPOS Some applications like to prepend the count with a zero to aid sorting, (i.e 02 comes before 10)

boolean	equals(java.lang.Object obj)
protected java.lang.String	getTextEncodingCharSet() Get the text encoding being used.
PartOfSet.PartOfSetValue	getValue() Get value held by this Object
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.
java.lang.String	toString() Return String representation of datatype
byte[]	writeByteArray() Write String into byte array It will remove a trailing null terminator if exists if the option RemoveTrailingTerminatorOnWrite has been set.

Constructor Detail

PartOfSet

public PartOfSet(java.lang.String identifier,
                 AbstractTagFrameBody frameBody)

Creates a new empty PartOfSet datatype.

Parameters:

identifier - identifies the frame type

frameBody -

PartOfSet

public PartOfSet(PartOfSet object)

Copy constructor

Parameters:

object -

Method Detail

equals

public boolean equals(java.lang.Object obj)

Overrides:

equals in class AbstractDataType

Returns:

whether this and obj are deemed equivalent

readByteArray

public void readByteArray(byte[] arr,
                          int offset)
                   throws InvalidDataTypeException

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.

Specified by:

readByteArray in class AbstractDataType

Parameters:

arr - this is the buffer for the frame

offset - this is where to start reading in the buffer for this field

Throws:

java.lang.NullPointerException

java.lang.IndexOutOfBoundsException

InvalidDataTypeException

writeByteArray

public byte[] writeByteArray()

Write String into byte array

It will remove a trailing null terminator if exists if the option RemoveTrailingTerminatorOnWrite has been set.

Specified by:

writeByteArray in class AbstractDataType

Returns:

the data as a byte array in format to write to file

getTextEncodingCharSet

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.

Returns:

the text encoding charset

getValue

public PartOfSet.PartOfSetValue getValue()

Description copied from class: AbstractDataType

Get value held by this Object

Overrides:

getValue in class AbstractDataType

Returns:

value held by this Object

toString

public java.lang.String toString()

Description copied from class: AbstractString

Return String representation of datatype

Overrides:

toString in class AbstractString

Returns:

a string representation of the value
