public final class DynamicCompositePageSegment
extends AbstractCompositePageSegment

Within a DynamicCompositePageSegment (dcps) one or more PageSegments can be arranged by transformations and clippings. In difference to a CompositePageSegment the bounds of a dcps are dynamically calculated, using the added PageSegments and AffineTransforms:

• The upper left corner is always x=0 and y=0. Therefore the dcps can only "grow" in positive x- and y-direction, negative bounds are not included to the resulting bounds. This has to be considered when adding transformed pageSegments.
• When clipping a pageSegment, only the remaining shape is included to the bounds.

A dcps is not delegating AbstractPageSegment.getPermissions(), AbstractPageSegment.getProperties() or AbstractPageSegment.getSource() to its child-segments. If needed, this has to be done manually using the according getters and setters.

public DynamicCompositePageSegment()

Method Detail

getBounds

public Rectangle2D getBounds()

Description copied from interface: PageSegment

Returns the raw size and position of the PageSegment in base units. Position is measured in relation to the Page's coordinate system's origin point (0,0).

Specified by:

getBounds in interface com.levigo.jadice.document.internal.model.RenderRoot

Specified by:

getBounds in interface PageSegment

Overrides:

getBounds in class AbstractPageSegment

Returns:

the raw size and position

getSize

public Dimension2D getSize()

Description copied from interface: PageSegment

Returns the raw size/dimensions of the PageSegment in base units.

Specified by:

getSize in interface PageSegment

Overrides:

getSize in class AbstractPageSegment

Returns:

the PageSegment's raw size

fireModified

protected void fireModified()

Description copied from class: AbstractMutablePageSegment

Fire a notification about a general change to the page segment. Please consider firing a more specialized one, indicating the actual damage region.

Overrides:

fireModified in class AbstractCompositePageSegment
