Interface IAnnotationManager

public interface IAnnotationManager

This interface manages the selection cycle for AnnotationComponents. AnnotationComponents can be programmatically selected and deselected with selectAnnotationComponent(AnnotationComponent) and deselectAnnotationComponent(AnnotationComponent).

Listeners can register with this class with addSelectionListener(IAnnotSelectionListener).

An implementation of this class can be obtained from the main class in your library, i.e. PDFViewerBean or PDFDocument.

Method Detail

addComponentToSelection

void addComponentToSelection(AnnotationComponent ac)

Adds an annotation component to the list of selected annotations.

Parameters:

ac - The annotation component to add

addSelectionListener

void addSelectionListener(IAnnotSelectionListener listener)

Adds a selection listener to the manager. Selection listeners will be notified when any annotations are selected or deselected.

Parameters:

listener - The new listener

removeSelectionListener

boolean removeSelectionListener(IAnnotSelectionListener listener)

Removes the specified selection listener so that it no longer receives annotation selection events from the manager.

Parameters:

listener - The listener to remove

Returns:

true if listener existed on the manager

clearSelection

void clearSelection()

Clears the current annotation component selection. Any annotation components that are selected will be deselected.

deselectAnnotationComponent

void deselectAnnotationComponent(AnnotationComponent ac)

Deselects an annotation.

Parameters:

ac - The annotation to deselect

getSelectedComponents

Vector<AnnotationComponent> getSelectedComponents()

Returns a list of annotation components that are selected. The list contains objects that implement AnnotationComponent.

Returns:

a list of selected annotation components

isSelected

boolean isSelected(AnnotationComponent ac)

Returns a flag that indicates whether the selection component is selected.

Parameters:

ac - The annotation component

Returns:

true if selected, false otherwise

selectAnnotationComponent

void selectAnnotationComponent(AnnotationComponent ac)

Selects an annotation.

Parameters:

ac - The annotation to select

selectAnnotationComponents

void selectAnnotationComponents(AnnotationComponent[] acs)

Selects a list of annotations.

Parameters:

acs - The annotations to select
