Method Detail

doExtract

protected X doExtract(ResultSet rs,
                      String name,
                      WrapperOptions options)
               throws SQLException

Description copied from class: BasicExtractor

Perform the extraction.

Called from BasicExtractor.extract(java.sql.ResultSet, java.lang.String, 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>

Parameters:

rs - The result set

name - The value name in the result set

options - The binding options

Returns:

The extracted value.

Throws:

SQLException - Indicates a problem access the result set

doExtract

protected X doExtract(CallableStatement statement,
                      int index,
                      WrapperOptions options)
               throws SQLException
