Method Detail

id

public String id()

setD2wContext

public void setD2wContext(com.webobjects.directtoweb.D2WContext context)

Description copied from class: ERDCustomComponent

Sets the D2WContext. Applies when used inside a property key repetition.

Overrides:

setD2wContext in class ERDCustomComponent

updateContainerIDs

public NSMutableArray<String> updateContainerIDs()

propertyChanged

public void propertyChanged(NSNotification n)

registerPropertyObserverID

public void registerPropertyObserverID(NSNotification n)

handleQueryWithUnboundKey

public Object handleQueryWithUnboundKey(String key)

Since this component uses synchronization to update observers when the d2wContext changes, it cannot be non-synchronizing. However, if we want to be able to drop this component anywhere, it needs to be able to accept any binding value. So this method simply returns value for key from the dynamicBindings dictionary.

Specified by:

handleQueryWithUnboundKey in interface NSKeyValueCoding.ErrorHandling

Overrides:

handleQueryWithUnboundKey in class WOComponent

handleTakeValueForUnboundKey

public void handleTakeValueForUnboundKey(Object value,
                                         String key)

Since this component uses synchronization to update observers when the d2wContext changes, it cannot be non-synchronizing. However, if we want to be able to drop this component anywhere, it needs to be able to accept any binding value. So this method simply adds value for key to the dynamicBindings dictionary.

Specified by:

handleTakeValueForUnboundKey in interface NSKeyValueCoding.ErrorHandling

Overrides:

handleTakeValueForUnboundKey in class WOComponent
