[jira] [Commented] (DAFFODIL-1934) Inability to read data following a layer


    [ https://issues.apache.org/jira/browse/DAFFODIL-1934?page=com.atlassian.jira.plugin.system.issuetabpanels:comment-tabpanel&focusedCommentId=16464074#comment-16464074 ] 

Michael Beckerle commented on DAFFODIL-1934:
--------------------------------------------

for line folding, currently layerLengthKind 'implicit' goes on until "end of data". layerLengthKind 'boundaryMark' has a fixed boundary mark of CRLF not followed by space or tab. 

Neither does what this example needs.  Suggest the header element use lengthKind='pattern' with a regex that isolates the header data. Then layerLengthKind 'implicit' will be constrained to only that data.

> I have a schema that has two parts: a header and a body. The header contains an unbounded array of delimited fields. The header has a terminator to signify when the fields are complete. The entire header element is in a lineFolded_IMF layered sequence. Immediately following the layered sequence is a body element, which is just a delimited string. The header fields and terminator are parsed correctly. However, the body is parsed with length zero, and no error is given about left over data. Perhaps the limiting layer is not being reset to the original layer correctly? So the layer IOStream is closed, making it so no data after the layer can be read?
