oracle.adfinternal.model.adapter.generic
Class BeanAbstractAdapter

java.lang.Object
oracle.adf.model.adapter.AbstractAdapter
oracle.adfinternal.model.adapter.generic.BeanAbstractAdapter

Direct Known Subclasses:

BeanAdapter, EjbAdapter, TopLinkAdapter

public abstract class BeanAbstractAdapter

extends AbstractAdapter

DataControlStructure driven AbstractAdapter implementation. This class handles the AbstractDefinition creation lifecycle and initialization based on the registered DataControlStructureProvider for the given adapter. Implementors of this class must implement the getDefinition(DataControlStructure) method providing the concrete AbstractDefinition as well as the getProviderType() method indicating the DataControlStructureProvider registered with the environment for this Adapter.

DataControlStructureProvider, DCStructureProviderFactory, DataControlStructure

Constructor Summary

BeanAbstractAdapter()

Method Summary

boolean	canCreateDataControl(java.lang.Object source) Defers to the DataControlStructureProvider indicated by getProviderType() to determine if this Adapter can create the AbstractDefinition for the source object.
void	configureClientProject(java.lang.Object sourceObj, DTContext ctx) Hook to allow specific adapter implementations to configure a client project.
AbstractDefinition	getDefinition() Constructs and returns the AbstractDefinition.
protected abstract AbstractDefinition	getDefinition(DataControlStructure dcStructure) Implementing classes must define this method to return the correct AbstractDefinition instance based on the given DataControlStructure.
protected abstract java.lang.String	getProviderType() Indicates the DataControlStructureProvider type registered with the DCStructureProviderFactory to call during DataControlStructure creation.
protected DataControlStructureProvider	getStructureProvider() Convenience method for obtaining the DataControlStructureProvider.
void	initialize(java.lang.Object sourceObj, DTContext ctx) Caches objects passed in during initialization.
boolean	invokeUI() Invokes the DataControlStructureProvider indicated by the provider type to do environment specific initialization of the DataControlStructure used in construction of the AbstractDefinition.

Method Detail

initialize

public final void initialize(java.lang.Object sourceObj,
                             DTContext ctx)

Caches objects passed in during initialization.

Specified by:

initialize in class AbstractAdapter

Parameters:

sourceObj - Object that contains information about the data source that will be used to define the data control.

ctx - Current design time context.

getDefinition

public final AbstractDefinition getDefinition()

Constructs and returns the AbstractDefinition.

Specified by:

getDefinition in class AbstractAdapter

getDefinition

protected abstract AbstractDefinition getDefinition(DataControlStructure dcStructure)

Implementing classes must define this method to return the correct AbstractDefinition instance based on the given DataControlStructure.

getProviderType

protected abstract java.lang.String getProviderType()

Indicates the DataControlStructureProvider type registered with the DCStructureProviderFactory to call during DataControlStructure creation.

invokeUI

public boolean invokeUI()

Invokes the DataControlStructureProvider indicated by the provider type to do environment specific initialization of the DataControlStructure used in construction of the AbstractDefinition.

Overrides:

invokeUI in class AbstractAdapter

Returns:

false if the user cancels the operation. The default retrun value is true.

canCreateDataControl

public boolean canCreateDataControl(java.lang.Object source)

Defers to the DataControlStructureProvider indicated by getProviderType() to determine if this Adapter can create the AbstractDefinition for the source object.

Overrides:

canCreateDataControl in class AbstractAdapter

Returns:

true if it can create a data control from the source.

getStructureProvider

protected DataControlStructureProvider getStructureProvider()

Convenience method for obtaining the DataControlStructureProvider.

configureClientProject

public void configureClientProject(java.lang.Object sourceObj,
                                   DTContext ctx)

Description copied from class: AbstractAdapter

Hook to allow specific adapter implementations to configure a client project.

Overrides:

configureClientProject in class AbstractAdapter

Parameters:

sourceObj - Object that contains information about the data source that will be used to define the data control.

ctx - Current design time context.
