FlatClassMapping

public FlatClassMapping(ClassMetaData meta)

Constructor. Supply underlying metadata.

Method Detail

isVirtualMapping

public boolean isVirtualMapping()

Description copied from interface: ClassMapping

Returns false if this mapping represents a table in the database.

getVersionIndicator

public VersionIndicator getVersionIndicator()

Description copied from interface: ClassMapping

Return the version indicator for this class. Subclass mappings should delegate this method to their superclass.

setVersionIndicator

public void setVersionIndicator(VersionIndicator version)

Description copied from interface: ClassMapping

Set the version indicator for this class. Subclass mappings should delegate this method to their superclass.

getClassIndicator

public ClassIndicator getClassIndicator()

Description copied from interface: ClassMapping

Return the class indicator for this class. Subclass mappings should delegate this method to their superclass.

setClassIndicator

public void setClassIndicator(ClassIndicator cls)

Description copied from interface: ClassMapping

Set the class indicator for this class. Subclass mappings should delegate this method to their superclass.

getTable

public Table getTable()

Description copied from interface: Mapping

Return the mapping's primary data table.

getPrimaryKeyColumns

public Column[] getPrimaryKeyColumns()

Description copied from interface: ClassMapping

Return the columns this mapping uses to uniquely identify an object. These will typically be the primary key columns or the columns this class uses to link to its superclass table. This method must be available before resolve.

isPrimaryKeyObjectId

public boolean isPrimaryKeyObjectId(boolean hasAll)

Description copied from interface: ClassMapping

Return true if the this class' primary key columns correspond to the base class' primary key columns used to construct oid values. Base classes always return true. Classes that join to the base class table, though, may not always join using the same columns the base class uses for oid values, or may not use all the columns. When performing a select, we will join down to the most-derived class that is identified by oid values. We cannot use non-primary key field values for joining during selects, because the field values to join on might be the ones we're trying to select! Similarly, we can only reconstruct oid values for selected object using classes whose primary keys store oid values.

Following copied from interface: kodo.jdbc.meta.ClassMapping

Parameters:

hasAll - if true, there must be a primary key column for every base class primary key column; if false the primary key must only match a subset of the base class primary key columns

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.

toMappingInfo

public void toMappingInfo(MappingInfo info)

Description copied from interface: Mapping

Serialize this mapping to a simple MappingInfo instance for transfer to XML or some other format.

fromMappingInfo

public void fromMappingInfo(MappingInfo info,
                            boolean adapt)

Description copied from class: AbstractClassMapping

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 AbstractClassMapping

Following copied from class: kodo.jdbc.meta.AbstractClassMapping

See Also:

AbstractClassMapping.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.

refSchemaComponents

public void refSchemaComponents()

Description copied from interface: Mapping

Increment the reference count of all used schema components.

joinSuperclass

public Joins joinSuperclass(Joins joins,
                            boolean toThis)

Description copied from interface: ClassMapping

Join the mapping and its superclass.

Following copied from interface: kodo.jdbc.meta.ClassMapping

Parameters:

toThis - if false, inner join to the superclass table; if true, outer join from the superclass table to this table

insert

public void insert(KodoStateManager sm,
                   RowManager rm)
            throws SQLException

Description copied from interface: Mapping

Set values for the mapping into the proper rows. For class mappings, this method will be called only after the corresponding method has been called for all fields of this mapping.

update

public void update(KodoStateManager sm,
                   RowManager rm)
            throws SQLException

Description copied from interface: Mapping

Set values for the mapping into the proper rows.

Mapping.insert(kodo.runtime.KodoStateManager, kodo.jdbc.sql.RowManager)

delete

public void delete(KodoStateManager sm,
                   RowManager rm)
            throws SQLException

Description copied from interface: Mapping

Set the where values appropriately to delete the proper instance, and set all relations on non-secondary tables as updates. This allows foreign key analysis.
