TYPE
public static final String TYPE
ClobFieldMapping
public ClobFieldMapping(FieldMetaData meta)
- Constructor. Supply underlying metadata.
getMappingType
public String getMappingType()
- Description copied from interface:
Mapping
- Return the abbreviated name of this mapping, or the full class name if
it is a custom mapping.
fromMappingInfo
public void fromMappingInfo(MappingInfo info,
boolean adapt)
- Description copied from class:
AbstractFieldMapping
- The default implementation will raise warnings for any mapping
attributes that are declared but not in the list of the valid
attributes for this mapping.
- Overrides:
fromMappingInfo
in class ColumnFieldMapping
- Following copied from class:
kodo.jdbc.meta.AbstractFieldMapping
- See Also:
AbstractFieldMapping.addMappingInfoAttributes(java.util.Collection)
map
public boolean map()
- Description copied from interface:
Mapping
- Map a new instance of this mapping type. If the underlying
metadata cannot be mapped using this type, return false.
- Overrides:
map
in class ColumnFieldMapping
reverseMap
public void reverseMap(SchemaGroup schema,
ReverseMappingTool tool)
- Description copied from interface:
Mapping
- Create mappings from the schema, using the given tool.
Implement this method if you want the class mapping to be a candidate
when reverse-mapping a schema to java classes. Note that this
method will be invoked on a template instance, so you cannot rely
on the metadata or owning repository being set.
- Overrides:
reverseMap
in class AbstractFieldMapping
select
public int select(Select sel,
KodoStateManager sm,
JDBCStoreManager store,
JDBCFetchConfiguration fetch,
int eagerMode)
- Description copied from interface:
FieldMapping
- Select the virtual row columns of this mapping.
- Overrides:
select
in class ColumnFieldMapping
- Following copied from interface:
kodo.jdbc.meta.FieldMapping
- Parameters:
sel
- the select to add tosm
- the instance being loaded, or null if not
initialized yet or selecting for multiple instancesstore
- the current store managerfetch
- fetch configurationeagerMode
- the eager fetch mode to use; this may be more
restrictive than the mode of the fetch configuration- Returns:
- > 0 if this mapping requires the selected data
(if any), 0 if it selected data but does not
require it, or < 0 if no data was selected
load
public void load(KodoStateManager sm,
JDBCStoreManager store,
JDBCFetchConfiguration fetch,
Result res)
throws SQLException
- Description copied from interface:
FieldMapping
- Load virtual row data; the given result is not guaranteed to contain
data for this field, so the field mapping should make sure the
result contains its needed column data before loading.
load
public void load(KodoStateManager sm,
JDBCStoreManager store,
JDBCFetchConfiguration fetch)
throws SQLException
- Description copied from interface:
FieldMapping
- Load secondary data using a connection from the store manager.
- Overrides:
load
in class ColumnFieldMapping
loadProjection
public Object loadProjection(JDBCStoreManager store,
JDBCFetchConfiguration fetch,
Result res,
Joins joins)
throws SQLException
- Description copied from interface:
FieldMapping
- Load this field value using the given result. This method will only
be called if this field does not represent a FCO relation. The result
will contain the columns from
FieldMapping.getColumns()
.
update
protected void update(KodoStateManager sm,
Row row)
throws SQLException
- Description copied from class:
ColumnFieldMapping
- Update this column with the current value into the given row.
- Overrides:
update
in class ColumnFieldMapping
