Applies the specified function to all the elements of which the 2D bounds overlap with the specified bounds.

int applyOnInteract2DBounds(ILcdBounds aBounds, boolean aStrictInteract, ILcdFunction aFunctionToApply, double aPrecisionX, double aPrecisionY, double aMinSizeX, double aMinSizeY, boolean aIncludePoints)
Only elements that have at least the specified minimal size in the x dimension or in the y dimension are considered. This can be useful for quickly eliminating elements that are too small to be visible in a view, for instance. If required, an exception can be made for point elements, which have a size of 0 by 0. They can be forced to be considered, even though they would always be rejected as being too small for any sizes larger than 0.
The return value of the specified function is used as a stop criterion: the spatial query will be interrupted
as soon as the function returns false
for an element it was applied on.
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.aFunctionToApply
 the function to apply on each element that overlaps with the given bounds.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 multileveled 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 lazyloaded implementations to load lots of data.
aPrecisionY
 the precision required in the y dimension, expressed in model units.aMinSizeX
 the minimal element size in the x dimension (as in
ILcdBounds.getWidth()
), 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
 if true
, zerosized elements (points) are considered as well, even though they
might be smaller than the minimum size.ILcdFunction
has been applied.java.lang.NullPointerException
 if the specified bounds or the specified function are null
.
