Method Detail

init

public void init(Source source,
                 Node fieldNode)
          throws PortalException

Description copied from interface: ISourceField

Initializes this source field. This method is called by the source after the field is created and before it is used. The implementation of this method must initialize all of this instance's attributes.

Specified by:

init in interface ISourceField

Overrides:

init in class GenericTableSourceField

Parameters:

source - the source this field will belong to.

fieldNode - the xml node that contains this field's definition.

Throws:

PortalException - if this field could not be initialized.

createDataType

protected ISourceFieldDataType createDataType()
                                       throws PortalException

Description copied from class: BaseSourceField

Factory method that creates a data type instance for this field. This method is called during BaseSourceField.init(Source, Node).

Overrides:

createDataType in class BaseSourceField

Returns:

the data type instance created.

Throws:

PortalException

getTableMapping

public TableSourceFieldMapping getTableMapping(QueryBase queryBase)
                                        throws PortalException

Description copied from interface: ITableSourceField

Returns the table mapping for this field. This specifies how the field data is accessed.

Specified by:

getTableMapping in interface ITableSourceField

Overrides:

getTableMapping in class GenericTableSourceField

queryBase - the query the mapping will be used.

Returns:

the field table mapping.

Throws:

PortalException

isInsertable

protected boolean isInsertable()

Description copied from class: BaseTabularSourceField

Indicates if the value this field represents may be inserted.

Overrides:

isInsertable in class BaseTabularSourceField

Returns:

true if this field's value may be inserted, false otherwise.

isUpdatable

protected boolean isUpdatable()

Description copied from class: BaseTabularSourceField

Indicates if the value this field represents is updatable.

Overrides:

isUpdatable in class BaseTabularSourceField

Returns:

true if this field's value is updatable, false otherwise.

getQueryField

protected QueryField getQueryField(QueryBase queryBase)
                            throws PortalException
