Method Details

getFormScope

public String getFormScope()

Specified by:

getFormScope in interface FacadeHandlerContext

matchesScope

public boolean matchesScope(Set<String> scopes)

Compares if the current form scope is included in @param scopes.

Parameters:

scopes - The scopes to compare to with the current form scope.

Returns:

true if it is included, or scopes is empty which means all are ok.

setFormScope

public void setFormScope(String formScope)

getTextResources

public TextResources getTextResources()

Specified by:

getTextResources in interface FacadeHandlerContext

setTextResources

public void setTextResources(TextResources textResources)

setComponent

public void setComponent(Component component)

getComponent

public Component getComponent()

Description copied from interface: FacadeHandlerContext

Returns the current component, which in fact is just the one you expect, because you already have told the system within the method.

Use FacadeHandlerContext.getComponent(Class) when you don't want to cast. This is save because you know the type.

Specified by:

getComponent in interface FacadeHandlerContext

Returns:

the current component

getParentFacade

public ComponentFacade getParentFacade()

Description copied from interface: FacadeHandlerContext

Get the parent facade. When we need it, we can extend the ComponentFacade interface so we can browse the already constructed structure a bit better.

But in some cases (eg. the table column) we know exacly what the parent must be and thus we can cast or use FacadeHandlerContext.getCurrentFacade(Class) to retrieve facade.

Specified by:

getParentFacade in interface FacadeHandlerContext

Returns:

the parent facade

setPathIdentifier

public void setPathIdentifier(@Nullable
 @Nullable String pathIdentifier)

getPathIdentifier

@Nullable
public @Nullable String getPathIdentifier()

Description copied from interface: FacadeHandlerContext

Get the current path identifiert. eg. 'firstname', 'relPrincipal', 'Address' ...

Specified by:

getPathIdentifier in interface FacadeHandlerContext

Returns:

The identifier, or null if it's not a data component.

setParentFacade

public void setParentFacade(@Nullable
 @Nullable ComponentFacade parentFacade)

getComponent

public <T extends Component> T getComponent(Class<T> clazz)
                                     throws RuntimeException

Description copied from interface: FacadeHandlerContext

Type-safe equivalent to the FacadeHandlerContext.getComponent() method

Specified by:

getComponent in interface FacadeHandlerContext

Type Parameters:

T - type parameter

Parameters:

clazz - the class

Returns:

component in expected type

Throws:

RuntimeException - with cause ClassCastException

getCurrentFacade

public <T extends ComponentFacade> T getCurrentFacade(Class<T> clazz)

Description copied from interface: FacadeHandlerContext

See FacadeHandlerContext.getParentFacade(). Additional possibility to move the cast into the context.

Specified by:

getCurrentFacade in interface FacadeHandlerContext

Type Parameters:

T - the type in which we expect the facade to be

Parameters:

clazz - the class in which we expect the facade to be

Returns:

the facade in the specific type
