file - the filename to the BLOB. May be relative to the job dir.
offset - the offset (in bytes) into the LobFile for this record.
length - the length of the record in bytes.
Method Detail

parse

public static BlobRef parse(java.lang.String inputString)
Deprecated. 
Create a BlobRef based on parsed data from a line of text. This only operates correctly on external blobs; inline blobs are simply returned as null. You should store BLOB data in SequenceFile format if reparsing is necessary.

Parameters:
inputString - the text-based input data to parse.
Returns:
a new BlobRef containing a reference to an external BLOB, or an empty BlobRef if the data to be parsed is actually inline.
