public class TLcdS52GXYLayer extends TLcdGXYLayer
A layer that adds support for the specific rendering requirements of S-52. Use this layer for
visualization of individual ENC cells. For catalogues, use
In particular, this layer ensures that for edges which are part of multiple objects, each edge is only painted once, using the line style of the object with the highest display priority.
This layer only works with a
TLcdS52GXYPainterProvider painter provider.
Note: in versions prior to V2013.1, the layer could only handle the
ordered models (see
and the ECDIS developer guide). As of V2013.1, it is no longer needed to order the models
before passing them to the layer. The layer can now handle both ordered as well as non-ordered
TLcdLayer.getModel() method will always return the model which was set on the layer.
|Constructor and Description|

public TLcdS52GXYLayer(ILcdModel aS57Model)
aS57Model- the model list to set on this layer.
public TLcdS52GXYLayer(ILcdModel aModel, TLcdS52DisplaySettings aDisplaySettings)
aModel- the model list to set on this layer.
aDisplaySettings- the S-52 display settings to be used for this layer.
public void setFilter(ILcdFilter aFilter)
ILcdFilter to filter the
Object on this
ILcdLayer. Operations on this layer will only be applied to objects of the model
that pass the filter. This includes painting, labeling, selection, editing, ...
If the filter implements
ILcdChangeSource, the layer will listen to changes in the filter to
keep, for example, the selection up to date.
null filter, lets all objects pass for rendering. By default the filter is
The filtering performed by this filter is done inside the JVM, after the
data has been queried from the model and been passed to the layer.
TLcdGXYLayer.setModelQueryConfiguration(TLcdModelQueryConfiguration) if you
have filters which should be evaluated on the model side.
For example when using a database model, this would allow the database to do the filtering.

public void setGXYPainterProvider(ILcdGXYPainterProvider aGXYPainterProvider)
TLcdGXYLayer. During painting, the provider will be queried to return a painter for the relevant domain objects. If no painter provider is set to this layer, nothing will be rendered. This call overwrites the painter provider array with a new one containing the given provider. Note that no property change listeners can be added to the painter provider, so the layer is not automatically notified when a property on the painter provider has changed. To notify the layer and its listeners, a property change event has to be fired, using the method
aGXYPainterProvider- the new painter provider
java.lang.IllegalArgumentException- if the specified painter provider is not an instance of
public void paint(java.awt.Graphics aGraphics, int aMode, ILcdGXYView aGXYView)
The mode indicates what objects of the model should be taken into account and what representation should be provided. The objects to be taken into account shall be one of:
Note that the combined representation may contain less than the representation of all objects that were taken into account, as some objects may be disregarded for various reasons (filters, scale, ... ). When the views scale is outside the scale range (BODIES or HANDLES mode) or the label scale range (LABELS mode) nothing shall be painted.
The representations provided shall be one or more of:
The mode supplied shall be a bitwise or combination of a constant of the first group and one or more of the
second group. When painting in BODIES or HANDLES mode, painting of an object shall be delegated to the
painter for that object, when the LABELS mode is passed, painting shall be delegated
labelpainter for that object.
The view is passed to provide contextual information: some of the objects may have a different representation depending on the view, or depending on a property of the view, for example, the scale of the view.
The combined representation of the objects has to be painted on the Graphics supplied, as these may be different from the Graphics provided by the view (due to double buffering, for example).
stopPainting is called, the current painting operation should be aborted.
If this layer is asked to paint its labels, it must inform its
ALcdLabelLocations instance as to which labels have been painted and which haven't
The paint mode may contain
This is a paint mode to indicate that only labels that are already placed should be painted. The
already placed labels can be retrieved from the
ALcdLabelLocations retrieved using

TLcdGXYLayer.applyOnInteractLabels(com.luciad.util.ILcdFunction, java.awt.Graphics, int, ILcdGXYView)
to determine which objects or labels should be painted. Customizing these methods will also
customize the painting behavior.
Objects smaller than the set minimum object size may be omitted.
aGraphics- the Graphics to paint on.
aMode- indicates what should be painted and how it should be painted.

ILcd2DBoundsIndexedModelthat interact with the view clip. The paint order is determined by the model.
public int applyOnInteract(ILcdFunction aFunction, java.awt.Rectangle aBounds, boolean aStrictInteract, ILcdGXYView aGXYView)
The function shall be applied successively to all objects in the bounds as long as the function returns
true for an object. This allows developers to indicate a stop condition. Note that the order in
which the objects are passed to the function is not specified.
When strict interaction is required, only objects whose representation lies within the given bounds, completely or partially, are candidates to be passed to the function. An object whose representation does not interact with the bounds should not be passed to the function. Applying non strict interaction can be useful to avoid heavy computations to determine whether an objects representation lies within the bounds.
This method behaves similar to the paint method, and as such is allowed to omit small or invisible objects for performance reasons.
Objects smaller than the set minimum object size may be omitted.
aFunction- the function to apply. When the function returns false, no more objects should be passed to the function.
aBounds- all objects who lie partially or completely in this area in the view are candidates to be passed to the function.
ILcdFunctionshall be applied only to the objects interacting with the given bounds. When false is passed, other objects may be taken into account too. When applying the function to an object consumes less time than checking whether an objects representation interacts with the bounds, non-strict interaction is generally faster.
aGXYView- the view in whose bounds the objects representations should be in order to be passed to the function.
