      fi.helsinki.cs.ohtu.mpeg2.video.ExtensionHeaderIdentifier

All Implemented Interfaces:

java.io.Serializable, java.lang.Comparable<ExtensionHeaderIdentifier>

public enum ExtensionHeaderIdentifier
extends java.lang.Enum<ExtensionHeaderIdentifier>

Identifies an MPEG extension header. Many headers in MPEG-2 are syntactically defined in terms of MPEG-1 extension headers. This enum identifies the types of these headers.

Method Detail

values

public static ExtensionHeaderIdentifier[] 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 (ExtensionHeaderIdentifier c : ExtensionHeaderIdentifier.values())
    System.out.println(c);

Returns:

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

valueOf

public static ExtensionHeaderIdentifier 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

writeTo

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

Writes the identifier to a bit stream.

Parameters:

stream - The stream to write to.

Throws:

java.io.IOException - Propagated from the stream write.
