public class BlobMapping

extends LobMapping

Represents the mapping of a BLOB column in the owning class' primary table. BLOBs are loaded and stored as secondary mappings for efficiency and due to the special handling needed to deal with them.

Method Detail

getSQLType

protected int getSQLType()

Description copied from class: LobMapping

Returns the SQLType code for this concrete LOB implementation.

Overrides:

getSQLType in class LobMapping

canMap

protected boolean canMap(FieldMetaData fmd,
                         ClassResolver resolver)

Description copied from class: FieldMapping

Return true if this mapping type can handle the given field, false otherwise. Note that this method cannot rely on the existance of other Mappings, as it is used in bootstrapping.

Overrides:

canMap in class LobMapping
