Subject [jira] Created: (DERBY-782) Improvement on org.apache.derby.impl.jdbc.EmbedBlob#length()
Date Fri, 23 Dec 2005 05:24:31 GMT
Improvement on org.apache.derby.impl.jdbc.EmbedBlob#length()
------------------------------------------------------------

         Key: DERBY-782
         URL: http://issues.apache.org/jira/browse/DERBY-782
     Project: Derby
        Type: Bug
  Components: JDBC  
    Reporter: Tomohito Nakayama


Now, org.apache.derby.impl.jdbc.EmbedBlob#length() method read out whole  BinaryToRawStream
to know exact length.

On the other hand,  BinaryToRawStream have some commented-out inplementation of having information
for length.

I think the information of lengh in BinaryToRawStream should be restored to be used in .org.apache.derby.impl.jdbc.EmbedBlob#length(),
because read out whole stream can be expensive processing when streamed information was large.

There exists a subject that reliability of lengh information in BinaryToRawStream is unknown.
