public class TLcdGML32LinearRing extends TLcdGML32AbstractRing implements ILcd3DEditablePolygon, ILcdRing, ILcdCache, ILcdInvalidateable

Model class for the GML Linear Ring Type.

A LinearRing is defined by four or more coordinate tuples, with linear interpolation between them; the first and last coordinates shall be coincident. The number of direct positions in the list shall be at least four.

The coordinates are stored in the POS_GROUP_PROPERTY.

An important difference between an ILcdPolygon and a GML3 Linear Ring is that in in GML3 the first and last point of a ring must be the same. As such, the implementation of ILcdPolygon will disregard the last point in the ring's points (typically a direct position list). Applications that set the ring's POS_GROUP_PROPERTY should follow GML conventions and ensure that the first and last point in the pos group is identical.

      insertIntoCache in interface ILcdCache
      Parameters:
      aKey - the key Object that will be used to identify the Object. The key must therefore be a unique identifier, typically the caller itself: insertIntoCache(this, ...).
      aObject - the Object to be cached.

      public Object removeCachedObject(Object aKey)
      Description copied from interface: ILcdCache

      Specified by:
      removeCachedObject in interface ILcdCache
      Parameters:
      aKey - the key Object that was used for storing the cache Object.
      Returns:
      the cached Object, or null if there was no Object corresponding to the given key.

    • invalidateObject

      public void invalidateObject()
      Description copied from interface: ILcdInvalidateable
      Invalidates all cached values of this object. Call this method whenever one or more of this object's compositing values has been changed, to notify this object it needs to recompute its cached values.
      Specified by:
      invalidateObject in interface ILcdInvalidateable

    • setValue

      public void setValue(TLcdDataProperty aProperty, Object aValue)
      Description copied from interface: ILcdDataObject

      Sets the value of the given property for this data object. The implementation is allowed to throw an exception if the given value can't be set.

      The given property must be declared in the data object's type or in one of its super types. In other words, getDataType().getProperties().contains( aProperty ) should always be true. Otherwise, the implementation should throw an IllegalArgumentException.

      Specified by:
      setValue in interface ILcdDataObject
      Overrides:
      setValue in class TLcdDataObject
      Parameters:
      aProperty - the property for which the value is to be set
      aValue - the value to set
