aBounds
- the rectangle to test overlap with.aStrictInteract
- if false
, the spatial search may return more elements than the ones strictly
overlapping; if true
, the search only returns the elements that are
overlapping. The latter mode is more precise, but it may be slower.aFunction
- the function to apply on each element that overlaps with the given bounds.
The return value of the specified function is used as a stop criterion: the spatial query is interrupted
if the function returns false
.aPrecisionX
- the precision required in the x dimension, expressed in model units.
For example, for a cartesian grid system expressed in meters, the values
should be expressed in meters as well, for a geodetic coordinate system the accuracy
values should be expressed in degrees.
The precision is useful in combination with multi-leveled data (multiple representations of the same object, but with varying accuracy), so that the most appropriate accuracy level can be used. 0 means best possible accuracy, but it might trigger lazy-loaded implementations to load lots of data.

- the precision required in the y dimension, expressed in model units.aMinSizeX
- the minimal element size in the x dimension (as in

), expressed in model units.
Elements that are smaller than this size will be skipped. This may, for example, be
useful when improving the efficiency of painting elements by skipping elements
that are smaller than some threshold (e.g. one pixel, converted to model units).aMinSizeY
- the minimal element size in the y dimension (as in
ILcdBounds.getHeight()
), expressed in model units.aIncludePoints

ILcdBounds
by which the geometry of this ILcdBounded

is bounded.
If the geometry does not allow retrieving valid bounds (for example a polyline with 0 points)
the return value is unspecified.
It is highly recommended to return an undefined

You can create undefined bounds using the default constructors
of TLcdLonLatBounds
or TLcdXYBounds
.

ILcdModel
Models that support this operation may place limitations on what elements may be added to this model. For example,
implementations that are based on a spatial indexing structure will require that elements implement
ILcdBounded
.
When adding an element, the user should make sure that canAddElement(aElement)
holds, and that the
element's geometry is expressed in the same model reference as this model. It is generally undefined what happens
if an invalid element is added.
Implementations of this interface should clearly specify in their documentation any restrictions on what elements
may be added. Although it is unspecified what happens if the preconditions are not met, implementations are
encouraged to throw meaningful exceptions (for example, NullPointerException, IllegalArgumentException,
ClassCastException, UnsupportedOperationException
), whenever possible.

ILcdModel
Registers the specified model listener to receive notifications of model changes on this model.
Model changes are sent out when an element has been added, removed or changed. Model changes can be sent out
individually, grouped or silently applied without notifications, depending on the ILcdFireEventMode
that was specified with the change.
In case you need to register a listener which keeps a reference to an object with a shorter life-time than this model,
you can use a ALcdWeakModelListener
instance as model listener.
