public class TLcdWMSProxyGXYLayer extends TLcdGXYLayer
ILcdGXYLayerimplementation is designed for models containing an
ALcdWMSProxyobject. The easiest way to create a WMS layer is by using
TLcdWMSProxyGXYLayerFactory. When creating the layer manually (e.g. by creating an instance of this class), for a minimal setup, the following should be configured:
ILcdModel: either through the constructor or the setter
ILcdGXYPainterProvider: typically either a
|Constructor and Description|
Creates a new WMS proxy GXY layer with an empty model.
Creates a new WMS proxy GXY layer with the specified model.

Applies the function to (at the least) all objects that are contained (partially or completely) in the bounds of the view.
Returns the view bounds of this
Paints the combined representation of the layer's objects for a view, taking into account the mode.
Inform the layer that it should terminate the current paint operation.

public TLcdWMSProxyGXYLayer(ILcdModel aModel, String aLabel)
aModel- the model
aLabel- the label
public int applyOnInteract(ILcdFunction aFunction, 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.
public ILcdBounds getBounds(int aMode, ILcdGXYView aGXYView) throws TLcdNoBoundsException
ILcdGXYLayercontent, the bounds of all the drawings (for the supplied mode) that represent the Objects contained in the
ILcdGXYLayer. For this operation, this
ILcdGXYLayeris to be considered as part of
Outside of the layers bounds no interaction with any object of the layer via its representation is possible. Note that these bounds do not necessarily encompass the representation of all objects in the model, only the objects for which there is a representation in the view.
aMode- a bitwise combination of ALL or SELECTION and one or more of BODIES and HANDLES. The
ILcdGXYLayer.LABELSmode is not supported.
aGXYView- the view in which the layer could be placed. This enables taking into account the views settings, for example the scale.
TLcdNoBoundsException- if the layer doesn't have any valid bounds, for example when none of the elements have a representation for the views current settings.
public void paint(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
