Method Detail

doExtract

protected X doExtract(ResultSet rs,
                      int paramIndex,
                      WrapperOptions options)
               throws SQLException

Description copied from class: BasicExtractor

Perform the extraction.

Called from BasicExtractor.extract(java.sql.ResultSet, int, org.hibernate.type.descriptor.WrapperOptions). Null checking of the value (as well as consulting ResultSet.wasNull()) is done there.

Specified by:

doExtract in class BasicExtractor<X>

Returns:

The extracted value.

Throws:

SQLException - Indicates a problem access the result set
