Constructor Detail

ProjectionAnnotationModel

public ProjectionAnnotationModel()
Creates a new, empty projection annotation model.

Method Detail

collapse

public void collapse(Annotation annotation)
Changes the state of the given annotation to collapsed. An appropriate annotation model change event is sent out.

Parameters:
annotation - the annotation

expand

public void expand(Annotation annotation)
Changes the state of the given annotation to expanded. An appropriate annotation model change event is sent out.

Parameters:
annotation - the annotation

toggleExpansionState

public void toggleExpansionState(Annotation annotation)
Toggles the expansion state of the given annotation. An appropriate annotation model change event is sent out.

Parameters:
annotation - the annotation

expandAll

public boolean expandAll(int offset,
                         int length)
Expands all annotations that overlap with the given range and are collapsed.

Parameters:
offset - the range offset
length - the range length
Returns:
true if any annotation has been expanded, false otherwise

expandAll

protected boolean expandAll(int offset,
                            int length,
                            boolean fireModelChanged)
Expands all annotations that overlap with the given range and are collapsed. Fires a model change event if requested.

Parameters:
offset - the offset of the range
length - the length of the range
fireModelChanged - true if a model change event should be fired, false otherwise
Returns:
true if any annotation has been expanded, false otherwise

modifyAnnotations

public void modifyAnnotations(Annotation[] deletions,
                              Map additions,
                              Annotation[] modifications)
Modifies the annotation model.

Parameters:
deletions - the list of deleted annotations
additions - the set of annotations to add together with their associated position
modifications - the list of modified annotations
