Constructor Summary
`BlobType()`

Method Summary
`int`	`compare(Object x, Object y, EntityMode entityMode)` compare two instances of the type
`Object`	`deepCopy(Object value, EntityMode entityMode, SessionFactoryImplementor factory)` Return a deep copy of the persistent state, stopping at entities and at collections.
`Serializable`	`disassemble(Object value, SessionImplementor session, Object owner)` Return a cacheable "disassembled" representation of the object.
`Object`	`fromXMLNode(org.dom4j.Node xml, Mapping factory)` Parse the XML representation of an instance.
`Object`	`get(ResultSet rs, String name)`
`int`	`getColumnSpan(Mapping mapping)` How many columns are used to persist this type.
`int`	`getHashCode(Object x, EntityMode entityMode)` Get a hashcode, consistent with persistence "equality"
`String`	`getName()` Returns the abbreviated name of the type.
`Class`	`getReturnedClass()` The class returned by `nullSafeGet()` methods.
`boolean`	`isDirty(Object old, Object current, boolean[] checkable, SessionImplementor session)` Should the parent be considered dirty, given both the old and current field or element value?
`boolean`	`isEqual(Object x, Object y, EntityMode entityMode)` Compare two instances of the class mapped by this type for persistence "equality" - equality of persistent state.
`boolean`	`isMutable()` Are objects of this type mutable.
`Object`	`nullSafeGet(ResultSet rs, String[] names, SessionImplementor session, Object owner)` Retrieve an instance of the mapped class from a JDBC resultset.
`Object`	`nullSafeGet(ResultSet rs, String name, SessionImplementor session, Object owner)` Retrieve an instance of the mapped class from a JDBC resultset.
`void`	`nullSafeSet(PreparedStatement st, Object value, int index, boolean[] settable, SessionImplementor session)` Write an instance of the mapped class to a prepared statement, ignoring some columns.
`void`	`nullSafeSet(PreparedStatement st, Object value, int index, SessionImplementor session)` Write an instance of the mapped class to a prepared statement.
`Object`	`replace(Object original, Object target, SessionImplementor session, Object owner, Map copyCache)` During merge, replace the existing (target) value in the entity we are merging to with a new (original) value from the detached entity we are merging.
`void`	`set(PreparedStatement st, Object value, int index, SessionImplementor session)`
`void`	`setToXMLNode(org.dom4j.Node node, Object value, SessionFactoryImplementor factory)` A representation of the value to be embedded in an XML element.
`int[]`	`sqlTypes(Mapping mapping)` Return the SQL type codes for the columns mapped by this type.
`boolean[]`	`toColumnNullness(Object value, Mapping mapping)` Given an instance of the type, return an array of boolean, indicating which mapped columns would be null.
`String`	`toLoggableString(Object value, SessionFactoryImplementor factory)` A representation of the value to be embedded in a log file.
