public interface ILspInteractivePaintableLayer extends ILspPaintableLayer, ILspStyledLayer

  • Method Details

    • getPainter

      ILspPainter getPainter(TLspPaintRepresentation aPaintRepresentation)
      Returns the painter currently associated with the specified paint representation, or null if no painter is associated.
      Parameters:
      aPaintRepresentation - the paint representation for which to obtain a painter
      Returns:
      the associated painter if it exists, or null otherwise
      Throws:
      IllegalArgumentException - if aPaintRepresentation is not supported

    • getEditor

      ILspEditor getEditor(TLspPaintRepresentation aPaintRepresentation)
      Returns the editor currently associated with the given paint representation, or null if no editor is associated.
      Parameters:
      aPaintRepresentation - the paint representation for which to retrieve an editor
      Returns:
      the associated editor if it exists, or null otherwise
      Throws:
      IllegalArgumentException - if aPaintRepresentation is not supported

    • getObjectsWithPaintState

      ILcdCollection<Object> getObjectsWithPaintState(TLspPaintState aState)
      Returns the objects in the specified paint state.

      The paint state must not be TLspPaintState.REGULAR, you can use query(com.luciad.view.lightspeed.query.ALspPaintQuery<T>, com.luciad.view.lightspeed.TLspContext) instead to get the current regular objects in the view.

      The state of objects can be modified by adding/removing them from the returned collection. You can be informed when the objects in a certain state change by adding a listener to the returned collection.

      To avoid threading issues when multiple threads read or write to these collections, it is required to take a read or write lock on this collection when you access it, using the TLcdLockUtil. For example: 

          ILcdCollection<Object> editedObjects = layer.getObjectsWithPaintState(TLspPaintState.EDITED);
    try (TLcdLockUtil.Lock lock = TLcdLockUtil.writeLock(editedObjects)) {
      editedObjects.add(newlySelectedObject, ILcdFireEventMode.FIRE_LATER);
    } finally {
      editedObjects.fireCollectedChanges();
    }
      Parameters:
      aState - a paint state
      Returns:
      the objects

    • editedObjectChanged

      void editedObjectChanged(Object aObject)
      This method should be called when an object that is being edited has changed significantly. As a result all editing listeners will be informed of this.
      Parameters:
      aObject - the object
      See Also:

    • editedObjectsChanged

      default void editedObjectsChanged(Collection<Object> aObjectList)
      This method should be called when a group of objects that is being edited has changed significantly. As a result, all editing listeners will be informed of this change.
      Parameters:
      aObjectList - A list of domain objects (in this layer) that have changed significantly. Never null.

    • addEditingStateListener

      void addEditingStateListener(ILspEditingStateListener aListener)
      Adds an ILspEditingStateListener to this ILspInteractivePaintableLayer.
      Parameters:
      aListener - the ILspEditingStateListener to be added.

    • removeEditingStateListener

      void removeEditingStateListener(ILspEditingStateListener aListener)
      Removes an ILspEditingStateListener from this ILspInteractivePaintableLayer.
      Parameters:
      aListener - the ILspEditingStateListener to be removed.

    • query

      <T> T query(ALspPaintQuery<T> aQuery, TLspContext aContext)
      Retrieves a set of domain objects and data based on the parameters given by the query.
      Type Parameters:
      T - the type of the return value of ALspPaintQuery.getResult()
      Parameters:
      aQuery - the query
      aContext - the context
      Returns:
      the value returned by ALspPaintQuery.getResult() after processing is finished
      Throws:
      UnsupportedOperationException - if an aspect of the query is not supported by this layer
