name - optional data name field (may be null for none)

data - the data to be added

Throws:

IOException - if adding the data fails for some reason

startArrayStructure

public void startArrayStructure(String name)
                         throws IOException

Description copied from interface: OutputFormatter

Starts an array structure. Following OutputFormatter.add(String, Object) calls will add elements to the array. Must be closed with OutputFormatter.endStructure()

Specified by:

startArrayStructure in interface OutputFormatter<String>

IOException - if starting this structure fails

endStructure

public void endStructure()
                  throws IOException

Description copied from interface: OutputFormatter

Ends a structure started before.

Specified by:

endStructure in interface OutputFormatter<String>

Throws:

IOException - if ending the actual structure fails

chunkCompleted
