Public Constructors
public NMLModelLODTreeLayer (NMLModelLODTreeDataSource dataSource)
Constructs a NMLModelLODTreeLayer object from a data source.
Parameters
| dataSource | The data source from which this layer loads data. |
|---|
Public Methods
public synchronized void delete ()
public NMLModelLODTreeDataSource getDataSource ()
Returns the data source of this layer.
Returns
- The data source that was bound to this vector layer on construction.
public float getLODResolutionFactor ()
Returns relative model LOD resolution.
Returns
- The relative model LOD resolution.
public long getMaxMemorySize ()
Returns memory usage constraints for the layer.
Returns
- The memory usage constraints for the layer.
public NMLModelLODTreeEventListener getNMLModelLODTreeEventListener ()
Returns the NML model event listener.
Returns
- The NML model event listener.
public boolean isUpdateInProgress ()
Tests whether this layer is being currently updated.
Returns
- True when the layer is being updated or false when the layer is in steady state.
public void setLODResolutionFactor (float factor)
Set relative model LOD resolution. Higher values than 1 result in higher details
(but slower performance and higher memory usage), while lower values give better
performance but lower quality. The default is 1.
Parameters
| factor | The relative LOD resolution factor. |
|---|
public void setMaxMemorySize (long size)
Set memory usage constraints for the layer. The specified limit is not exact,
but should be relatively close to the actual memory usage of the layer.
If specific view requires more data than specified limit, then lower LOD levels
of the models are used. The default is 80MB.
Parameters
| size | The memory limit in bytes. |
|---|
public void setNMLModelLODTreeEventListener (NMLModelLODTreeEventListener nmlModelLODTreeEventListener)
Sets the NML model event listener.
Parameters
| nmlModelLODTreeEventListener | The vector element event listener. |
|---|
