Method Detail

values

public static MP123Header.ModeExtension[] values()

Returns an array containing the constants of this enum type, in the order they are declared. This method may be used to iterate over the constants as follows:

for (MP123Header.ModeExtension c : MP123Header.ModeExtension.values())
    System.out.println(c);

Returns:

an array containing the constants of this enum type, in the order they are declared

valueOf

public static MP123Header.ModeExtension valueOf(java.lang.String name)

Returns the enum constant of this type with the specified name. The string must match exactly an identifier used to declare an enum constant in this type. (Extraneous whitespace characters are not permitted.)

Parameters:

name - the name of the enum constant to be returned.

Returns:

the enum constant with the specified name

Throws:

java.lang.IllegalArgumentException - if this enum type has no constant with the specified name

java.lang.NullPointerException - if the argument is null

getJSBound

public int getJSBound()

Returns the joint stereo bound for layers I and II. Does not have a meaning for layer III.

Returns:

the joint stereo bound

isIntensityStereo

public boolean isIntensityStereo()

Returns whether intensity stereo is used for layer III. Does not have a meaning for layers I and II.

Returns:

true iff intensity stereo is used

isMSStereo

public boolean isMSStereo()

Returns whether MS stereo is used for layer III. Does not have a meaning for layers I and II.

Returns:

true iff MS stereo is used

writeTo

public void writeTo(BitOutputStream stream)
             throws java.io.IOException

Encodes this ModeExtension to the given bit stream.

Parameters:

stream - the stream to encode this ModeExtension to

Throws:

java.io.IOException
