Enum Stream

java.lang.Object
  java.lang.Enum<Stream>
      eu.play_project.play_commons.constants.Stream

All Implemented Interfaces:

Serializable, Comparable<Stream>

public enum Stream
extends Enum<Stream>

Enum of stream identifiers (also used for topic names) commonly used in PLAY. Full stream IDs ending in #stream are used when creating metadata about streams, largely when describing the stream in RDF. Shorter IDs without this suffix are used for topics on the DSB which can be obtained by getTopicUri() and getTopicQName().

Method Detail

values

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

Returns:

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

valueOf

public static Stream valueOf(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:

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

NullPointerException - if the argument is null

getQName

public QName getQName()

getUri

public String getUri()

getTopicUri

public String getTopicUri()

Obtain short stream IDs for use with the DSB. This representation omits the trailing #stream suffix.

toTopicUri

public static String toTopicUri(String streamId)

Obtain short stream IDs for use with the DSB. This representation omits the trailing #stream suffix.

getTopicQName

public QName getTopicQName()

Obtain short stream IDs for use with the DSB. This representation omits the trailing #stream suffix.

toTopicQName

public static QName toTopicQName(QName streamId)

Obtain short stream IDs for use with the DSB. This representation omits the trailing #stream suffix.

toString

public String toString()

Overrides:
