    • applyOnInteract2DBounds

      public int applyOnInteract2DBounds(ILcdBounds aBounds, boolean aStrictInteract, ILcdFunction aFunction, double aPrecisionX, double aPrecisionY)
      Description copied from interface: ILcd2DBoundsIndexedModel
      Applies the specified function to all the model elements of which the 2D bounds overlap with the specified bounds. By default, the order in which the function is applied on the elements is unspecified and depends on the implementation.

      The return value of the specified function is used as a stop criterion: the spatial query is interrupted if the function returns false.

      Specified by:
      applyOnInteract2DBounds in interface ILcd2DBoundsIndexedModel
      Parameters:
      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.

      aPrecisionY - the precision required in the y dimension, expressed in model units.
      Returns:
      the number of elements to which the ILcdFunction has been applied.

    • applyOnInteract2DBounds

      public int applyOnInteract2DBounds(ILcdBounds aBounds, boolean aStrictInteract, ILcdFunction aFunction, double aPrecisionX, double aPrecisionY, double aMinSizeX, double aMinSizeY, boolean aIncludePoints)
      Description copied from interface: ILcd2DBoundsInteractable
      Applies the specified function to all the elements of which the 2D bounds overlap with the specified bounds. The order in which the function is applied on the elements is unspecified and depends on the implementation.

      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.

      Specified by:
      applyOnInteract2DBounds in interface ILcd2DBoundsIndexedModel
      Specified by:
      applyOnInteract2DBounds in interface ILcd2DBoundsInteractable
      Parameters:
      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.
      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.

      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, zero-sized elements (points) are considered as well, even though they might be smaller than the minimum size.
      Returns:
      the number of elements to which the ILcdFunction has been applied.

    • getBounds

      public ILcdBounds getBounds()
      Description copied from interface: ILcdBounded
      Returns the ILcdBounds by which the geometry of this ILcdBounded object 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 bounds. You can create undefined bounds using the default constructors of TLcdLonLatBounds or TLcdXYBounds.

      Specified by:
      getBounds in interface ILcdBounded
      Returns:
      the ILcdBounds by which the geometry of this ILcdBounded object is bounded.

    • addElement

      public void addElement(Object aObject, int i) throws IllegalArgumentException
      Description copied from interface: ILcdModel
      Adds the specified element to this model.

      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.

      Specified by:
      addElement in interface ILcdModel
      Parameters:
      aObject - the element to be added to this model.
      i - the mode for sending out the model change event. This can be FIRE_LATER or NO_EVENT.
      Throws:
      IllegalArgumentException
      See Also:

    • addElements

      public void addElements(Vector aVector, int i)
      Description copied from interface: ILcdModel
      Adds all of the elements in the specified vector to this model. 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. Implementations of this interface should clearly specify in their documentation any restrictions on what elements may be added.

      The behavior of this operation is undefined if the specified vector is modified while the operation is in progress.

      The specified elements will be added to this model in the order they are specified in the vector. If an element cannot be added, this method will return at the first failure. Succeeding elements won't 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.

      Specified by:
      addElements in interface ILcdModel
      Parameters:
      aVector - the vector of elements to be added to this model.
      i - the mode for sending the model change events This can be FIRE_LATER or NO_EVENT.

    • addModelListener

      public void addModelListener(ILcdModelListener aILcdModelListener)
      Description copied from interface: 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.

      Specified by:
      addModelListener in interface ILcdModel
      Parameters:
      aILcdModelListener - the ILcdModelListener to register on this model.

      Note that this method generally does not validate whether the specified element is expressed in the same model reference as this model. It is the responsibility of the user of this model to make sure this precondition is fulfilled when an element is added to this model.

      Specified by:
      canAddElement in interface ILcdModel
      Parameters:
