    • getHeaders

      MultivaluedMap<String,Object> getHeaders()

      See Also:

    • getStringHeaders

      MultivaluedMap<String,String> getStringHeaders()
      Get a string view of header values associated with the message. Changes in the underlying headers map are reflected in this view.

      The method converts the non-string header values to strings using a RuntimeDelegate.HeaderDelegate if one is available via RuntimeDelegate.createHeaderDelegate(java.lang.Class) for the class of the value or using the values toString method if a header delegate is not available.

      Returns:
      response headers as a string view of header values.
      See Also:

    • getHeaderString

      String getHeaderString(String name)
      Get a message header as a single string value. Each single header value is converted to String using a RuntimeDelegate.HeaderDelegate if one is available via RuntimeDelegate.createHeaderDelegate(java.lang.Class) for the header value class or using its toString method if a header delegate is not available.
      Parameters:
      name - the message header.
      Returns:
      the message header value. If the message header is not present then null is returned. If the message header is present but has no value then the empty string is returned. If the message header is present more than once then the values of joined together and separated by a ',' character.
