Method Detail

getStrategy

public Object getStrategy(Version vers,
                          boolean adapt)

Description copied from interface: MappingDefaults

Default version mapping strategy when there is no explicit strategy.

Specified by:

getStrategy in interface MappingDefaults

Overrides:

getStrategy in class MappingDefaultsImpl

Parameters:

vers - the version; will not be mapped, but raw MappingInfo will be available

adapt - whether we can adapt the mapping or schema

Returns:

the strategy alias or a strategy instance, or null

getStrategy

public Object getStrategy(Discriminator disc,
                          boolean adapt)

Description copied from interface: MappingDefaults

Default discriminator mapping strategy when there is no explicit strategy.

Specified by:

getStrategy in interface MappingDefaults

Overrides:

getStrategy in class MappingDefaultsImpl

Parameters:

disc - the discriminator; will not be mapped, but raw MappingInfo will be available

adapt - whether we can adapt the mapping or schema

Returns:

the strategy alias or a strategy instance, or null

getTableName

public String getTableName(ClassMapping cls,
                           Schema schema)

Description copied from interface: MappingDefaults

Return the default table name for the given class. This method is only called for classes mapped to their own table.

Specified by:

getTableName in interface MappingDefaults

Overrides:

getTableName in class MappingDefaultsImpl

getTableName

public String getTableName(FieldMapping fm,
                           Schema schema)

Description copied from interface: MappingDefaults

Return the default secondary table name for the given field. This method is only called for fields whose strategy requires a secondary table.

Specified by:

getTableName in interface MappingDefaults

Overrides:

getTableName in class MappingDefaultsImpl

populateJoinColumn

public void populateJoinColumn(FieldMapping fm,
                               Table local,
                               Table foreign,
                               Column col,
                               Object target,
                               int pos,
                               int cols)

Description copied from interface: MappingDefaults

Fill in default information for the given column used to join a field to its defining class' table. The column will be a clone of the target column, or have its name and Java type set in the case of a constant target.

Specified by:

populateJoinColumn in interface MappingDefaults

Overrides:

populateJoinColumn in class MappingDefaultsImpl

target - the target of this column in the join; may be another column or a constant value

pos - the index of this column in the logical foreign key

cols - the number of columns in the logical foreign key

populateForeignKeyColumn

public void populateForeignKeyColumn(ValueMapping vm,
                                     String name,
                                     Table local,
                                     Table foreign,
                                     Column col,
                                     Object target,
                                     boolean inverse,
                                     int pos,
                                     int cols)

Description copied from interface: MappingDefaults

Fill in default information for the given column used to join a value to its related type. The column will be a clone of the target column, or have its name and Java type set in the case of a constant target.

Specified by:

populateForeignKeyColumn in interface MappingDefaults

Overrides:

populateForeignKeyColumn in class MappingDefaultsImpl

name - base name for value, as decided by mapping

target - the target of this column in the join; may be another column or a constant value

inverse - whether this is an inverse foreign key

pos - the index of this column in the logical foreign key

cols - the number of columns in the logical foreign key

populateColumns

public void populateColumns(Version vers,
                            Table table,
                            Column[] cols)

Description copied from interface: MappingDefaults

Fill in default information for the given version columns. The columns' name and Java type will already be populated with generic defaults that may be replaced.

Specified by:

populateColumns in interface MappingDefaults

Overrides:

populateColumns in class MappingDefaultsImpl
