Method Detail

getSymbol

public static org.apache.qpid.proton.amqp.Symbol getSymbol(String key)

Lookup and return the correct Proton Symbol instance based on the given key.

Parameters:

key - the String value name of the Symbol to locate.

Returns:

the Symbol value that matches the given key.

getMessageAnnotation

public static Object getMessageAnnotation(String key,
                                          org.apache.qpid.proton.message.Message message)

Safe way to access message annotations which will check internal structure and either return the annotation if it exists or null if the annotation or any annotations are present.

Parameters:

key - the String key to use to lookup an annotation.

message - the AMQP message object that is being examined.

Returns:

the given annotation value or null if not present in the message.

Check whether the content-type field of the properties section (if present) in the given message matches the provided string (where null matches if there is no content type present.

Parameters:

contentType - content type string to compare against, or null if none

message - the AMQP message object that is being examined.

Returns:

true if content type matches
