Constructor Detail

ManyToManyMapping

public ManyToManyMapping(com.solarmetric.rd.kodo.meta.FieldMetaData meta)

Constructor. Supply underlying metadata.

Method Detail

getForeignKey

public com.solarmetric.rd.kodo.impl.jdbc.schema.ForeignKey getForeignKey()

Return the foreign key to the related object.

setForeignKey

public void setForeignKey(com.solarmetric.rd.kodo.impl.jdbc.schema.ForeignKey fk)

Set the foreign key to the related object.

getMappingType

public java.lang.String getMappingType()

Description copied from class: Mapping

Return the abbreviated name of this mapping, or the full class name if it is a custom mapping. Returns the full class name by default.

Overrides:

getMappingType in class Mapping

toMappingInfo

public void toMappingInfo(com.solarmetric.rd.kodo.impl.jdbc.meta.MappingInfo info)

Description copied from class: Mapping

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

Overrides:

toMappingInfo in class AbstractCollectionMapping

fromMappingInfo

public boolean fromMappingInfo(com.solarmetric.rd.kodo.impl.jdbc.meta.MappingInfo info,
                               boolean adapt)

Description copied from class: Mapping

Deserialize this mapping from a simple MappingInfo instance parsed from XML or some other format. If the info is incompatible and adapt is true, try to adapt to the new info, else return false. This method must validate the given mapping information using the SchemaGroup.findTable(java.lang.String) method to find any needed tables, the Table.getColumn(java.lang.String) method to retrieve columns from those tables, and the Column.isCompatible(int, int) method to check all column types. This is important, as some schema groups use these methods to build themselves up dynamically rather than reading schema information from the database.

Overrides:

fromMappingInfo in class AbstractCollectionMapping

map

public boolean map()

Description copied from class: 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 ContainerMapping

reverseMap

public void reverseMap(com.solarmetric.rd.kodo.impl.jdbc.schema.SchemaGroup schema,
                       com.solarmetric.rd.kodo.impl.jdbc.meta.ReverseMappingTool tool)

Description copied from class: 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 Mapping

isJoinTable

public static boolean isJoinTable(com.solarmetric.rd.kodo.impl.jdbc.schema.Table table,
                                  com.solarmetric.rd.kodo.impl.jdbc.meta.ReverseMappingTool tool)

Return true if the given table matches the pattern for a join table.

refSchemaComponents

public void refSchemaComponents()

Description copied from class: Mapping

Increment the reference count of all used schema components.

Overrides:

refSchemaComponents in class AbstractCollectionMapping

getColumns

public com.solarmetric.rd.kodo.impl.jdbc.schema.Column[] getColumns()

Description copied from class: FieldMapping

Return the data columns for this mapping. This corresponds to the field-order foreign key columns in relations.

Specified by:

getColumns in class FieldMapping

getDataStoreValue

public java.lang.Object getDataStoreValue(java.lang.Object val)

Description copied from class: FieldMapping

Translate the given field value to its datastore equivalent. If the mapping occupies multiple columns in the datastore, return an object array, else return a single object. Simply returns the given object by default.

Overrides:

getDataStoreValue in class FieldMapping

joinRelation

public void joinRelation(com.solarmetric.rd.kodo.impl.jdbc.runtime.Joins joins)

Description copied from class: FieldMapping

Join this value's table to the table for the related first class object type, if any.

Specified by:

joinRelation in class FieldMapping

selectVRowData

public java.lang.Boolean selectVRowData(com.solarmetric.rd.kodo.runtime.StateManagerImpl sm)

Description copied from class: FieldMapping

Return Boolean.TRUE if 'virtual row' data needs to be selected, Boolean.FALSE if it does not need to be, and null if it would be desirable to select it, but is not necessary.

Overrides:

selectVRowData in class ContainerMapping

select

public void select(com.solarmetric.rd.kodo.impl.jdbc.runtime.Select sel,
                   boolean multiple)

Description copied from class: FieldMapping

Select the virtual row columns of this mapping.

Overrides:

select in class ContainerMapping

Parameters:

sel - the select to add to

multiple - whether this select is expected to match multiple objects

load

public void load(com.solarmetric.rd.kodo.runtime.StateManagerImpl sm,
                 com.solarmetric.rd.kodo.impl.jdbc.runtime.JDBCStoreManager store,
                 com.solarmetric.rd.kodo.impl.jdbc.runtime.Result res)
          throws java.sql.SQLException
