Constructor Detail

ContainerMapping

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

Constructor. Supply underlying metadata.

Method Detail

getMetaDataColumn

public com.solarmetric.rd.kodo.impl.jdbc.schema.Column getMetaDataColumn()

Return the column holding the collection meta data.

setMetaDataColumn

public void setMetaDataColumn(com.solarmetric.rd.kodo.impl.jdbc.schema.Column col)

Set the column holding the collection meta data.

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 ReferenceMapping

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.

Specified by:

fromMappingInfo in class Mapping

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.

Specified by:

map in class Mapping

refSchemaComponents

public void refSchemaComponents()

Description copied from class: Mapping

Increment the reference count of all used schema components.

Overrides:

refSchemaComponents in class ReferenceMapping

appendIsEmpty

public void appendIsEmpty(com.solarmetric.rd.kodo.impl.jdbc.schema.SQLBuffer sql,
                          com.solarmetric.rd.kodo.impl.jdbc.runtime.Joins joins)

Description copied from class: FieldMapping

Create a where clause to the given statement asking if this value is empty.

Specified by:

appendIsEmpty in class FieldMapping

appendIsNull

public void appendIsNull(com.solarmetric.rd.kodo.impl.jdbc.schema.SQLBuffer sql,
                         com.solarmetric.rd.kodo.impl.jdbc.runtime.Joins joins)

Description copied from class: FieldMapping

Add a where clause to the given statement asking if this value is null.

Specified by:

appendIsNull in class FieldMapping

appendIsNotNull

public void appendIsNotNull(com.solarmetric.rd.kodo.impl.jdbc.schema.SQLBuffer sql,
                            com.solarmetric.rd.kodo.impl.jdbc.runtime.Joins joins)

Description copied from class: FieldMapping

Add a where clause to the given statement asking if this value is not null.

Specified by:

appendIsNotNull in class FieldMapping

join

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

Description copied from class: FieldMapping

Join this value to the class table.

Specified by:

join in class FieldMapping

getVRowTable

public com.solarmetric.rd.kodo.impl.jdbc.schema.Table getVRowTable()

Description copied from class: FieldMapping

Return the table this mapping uses for the columns that are part of the 'virtual row' that this object spans in the database. The virtual row can include multiple tables if some fields are stored in joined tables. However, the virtual row includes only those other tables that are guaranteed to have exactly one row in them for the object's corresponding row in the primary table.

Specified by:

getVRowTable 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.

Specified by:

selectVRowData in class FieldMapping

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.

Specified by:

select in class FieldMapping

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

Description copied from class: 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.

Specified by:

load in class FieldMapping
