Deprecated.

Initialize a BlobRef to an external BLOB.

Parameters:

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.
