public class ExplicitOracleBlobMapping

extends OracleBlobMapping

Represents the mapping of a field explicitly marked a BLOB by its metadata. The normal BLOB mapping is used as a catch-all; this one is tested first in case the user wants to use a BLOB for a field that could normally be persisted in another manner. This is for Oracle data stores only.

Field Summary

static String

BLOB Metadata extension key used to mark whether a field should be serialized as a blob.

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.
