    参数:
    
    cPtr - The native pointer of the instance.
    
    cMemoryOwn - The ownership flag.

  - getUTFGridDataSource
```
public TileDataSource getUTFGridDataSource()
```
    Returns the tile data source of the associated UTF grid. By default this is null.
    
    返回:
    
    The tile data source of the associated UTF grid.
  - setUTFGridDataSource
```
public void setUTFGridDataSource(TileDataSource dataSource)
```
    Sets the tile data source of the associated UTF grid.
    
    参数:
    
    dataSource - The data source to use. Can be null if UTF grid is not used.
  - getFrameNr
```
public int getFrameNr()
```
    Returns the current frame number.
    
    返回:
    
    The current frame number.
  - setFrameNr
```
public void setFrameNr(int frameNr)
```
    Sets the frame number, only used for animated tiles.
    Loading a new frame may take some time, previous frame is shown during loading.
    
    参数:
    
    frameNr - The frame number to display.
  - isPreloading
```
public boolean isPreloading()
```
    Returns the state of the preloading flag of this layer.
    
    返回:
    
    True if preloading is enabled.
  - setPreloading
```
public void setPreloading(boolean preloading)
```
    Sets the state of preloading for this layer. Preloading allows the downloading of tiles that are not
    currently visible on screen, but are adjacent to ones that are. This means that the user can pan the map without
    immediately noticing any missing tiles.
    
    Enabling this option might introduce a small performance hit on slower devices. It should also be noted that this
    will considerably increase network traffic if used with online maps. The default is false.
    
    参数:
    
    preloading - The new preloading state of the layer.
  - isSynchronizedRefresh
```
public boolean isSynchronizedRefresh()
```
    Returns the state of the synchronized refresh flag.
    
    返回:
    
    The state of the synchronized refresh flag.
  - setSynchronizedRefresh
```
public void setSynchronizedRefresh(boolean synchronizedRefresh)
```
    Sets the state of the synchronized refresh flag. If disabled all tiles will appear on screen
    one by one as they finish loading. If enabled the map will wait for all the visible tiles to finish loading
    and then show them all on screen together. This is useful for animated tiles.
    
    参数:
    
    synchronizedRefresh - The new state of the synchronized refresh flag.
  - getTileSubstitutionPolicy
```
public TileSubstitutionPolicy getTileSubstitutionPolicy()
```
    Returns the current tile substitution policy.
    
    返回:
    
    The current substitution policy. Default is TILE_SUBSTITUTION_POLICY_ALL.
  - setTileSubstitutionPolicy
```
public void setTileSubstitutionPolicy(TileSubstitutionPolicy policy)
```
    Sets the current tile substitution policy.
    
    参数:
    
    policy - The new substitution policy. Default is TILE_SUBSTITUTION_POLICY_ALL.
  - getZoomLevelBias
```
public float getZoomLevelBias()
```
    Gets the current zoom level bias for this layer.
    
    返回:
    
    The current zoom level bias for this layer.
  - setZoomLevelBias
```
public void setZoomLevelBias(float bias)
```
    Sets the zoom level bias for this layer.
    Higher zoom level bias forces SDK to use more detailed tiles for given view compared to lower zoom bias.
    The default bias is 0.
    
    参数:
    
    bias - The new bias value, both positive and negative fractional values are supported.
  - getMaxOverzoomLevel
```
public int getMaxOverzoomLevel()
```
    Gets the current maximum overzoom level for this layer.
    
    返回:
    
    The current maximum overzoom level for this layer.
  - setMaxOverzoomLevel
```
public void setMaxOverzoomLevel(int overzoomLevel)
```
    Sets the maximum overzoom level for this layer.
    If a tile for the given zoom level Z is not available, SDK will try to use tiles with zoom levels Z-1, ..., Z-MaxOverzoomLevel.
    The default is 6.
    
    参数:
    
    overzoomLevel - The new maximum overzoom value.
  - getMaxUnderzoomLevel
```
public int getMaxUnderzoomLevel()
```
    Gets the current maximum underzoom level for this layer.
    
    返回:
    
    The current maximum underzoom level for this layer.
  - setMaxUnderzoomLevel
```
public void setMaxUnderzoomLevel(int underzoomLevel)
```
    Sets the maximum underzoom level for this layer.
    If a tile for the given zoom level Z is not available, SDK will try to use tiles with zoom levels Z-1, ..., Z-MaxOverzoomLevel and then Z+1, ..., Z+MaxUnderzoomLevel.
    The default is 3.
    
    参数:
    
    underzoomLevel - The new maximum underzoom value.
  - calculateMapTileBounds
```
public MapBounds calculateMapTileBounds(MapTile mapTile)
```
    Calculates the tile corresponding to given geographical coordinates and zoom level.
    Note: zoom level bias is NOT applied, only discrete zoom level is used.
    
    参数:
    
    mapTile - The map tile to use.
    
    mapTile - The map tile to use.
    
    返回:
