    • replaceHeaders

      public void replaceHeaders(javax.ws.rs.core.MultivaluedMap<String,Object> headers)
      Replace all headers.
      Parameters:
      headers - new headers.

    • getStringHeaders

      public javax.ws.rs.core.MultivaluedMap<String,String> getStringHeaders()
      Get a multi-valued map representing outbound message headers with their values converted to strings.

    • getHeaderString

      public 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.

    • singleHeader

      private <T> T singleHeader(String name, Class<T> valueType, Function<String,T> converter, boolean convertNull)
      Get a single typed header value.
      Type Parameters:
      T - header value type.
      Parameters:
      name - header name.
      valueType - header value class.
      converter - from string conversion function. Is expected to throw ProcessingException if conversion fails.
      convertNull - if true this method calls the provided converter even for null. Otherwise this method returns the null without calling the converter.
      Returns:
      value of the header, or (possibly converted) null if not present.
