                                                  boolean cMemoryOwn)
```
    Creates a polymorphic instance of the given native object. This is used internally by the SDK.
    
    参数:
    
    cPtr - The native pointer of the instance.
    
    cMemoryOwn - The ownership flag.
    
    返回:
    
    The created instance.
  - equals
```
public boolean equals(java.lang.Object obj)
```
    Checks if this object is equal to the specified object.
    
    覆盖:
    
    equals 在类中 java.lang.Object
    
    参数:
    
    obj - The reference object.
    
    返回:
    
    True when objects are equal, false otherwise.
  - hashCode
```
public int hashCode()
```
    Returns the hash value of this object.

    返回:
    
    The hash value of this object.
  - getUpdatePriority
```
public int getUpdatePriority()
```
    Returns the layer task priority of this layer.
    
    返回:
    
    The priority level for the tasks of this layer.
  - setUpdatePriority
```
public void setUpdatePriority(int priority)
```
    Sets the layer task priority. Higher priority layers get to load data before
    lower priority layers. Normal layers and tile layers have seperate task queues and thus
    don't compete with each other for task queue access. The default is 0.
    
    参数:
    
    priority - The new task priority for this layer, higher values get better access.
  - getPriority
```
public int getPriority()
```
  - setPriority
```
public void setPriority(int priority)
```
  - setCullDelay
```
public void setCullDelay(int delay)
```
    Sets the layer culling delay. The culling delay is used to delay layer content rendering in case of user interaction,
    higher delay improves performance and battery life at the expense of interactivity. Default is 200ms-400ms, depending
    on layer type.
    
    参数:
    
    delay - The new culling delay in milliseconds.
  - isVisible
```
public boolean isVisible()
```
    Returns the visibility of this layer.
    
    返回:
    
    True if the layer is visible.
  - setVisible
```
public void setVisible(boolean visible)
```
    Sets the visibility of this layer.
    
    参数:
    
    visible - The new visibility state of the layer.
  - getVisibleZoomRange
```
public MapRange getVisibleZoomRange()
```
    Returns the visible zoom range of this layer.
    
    返回:
    
    The visible zoom range of this layer.
  - setVisibleZoomRange
```
public void setVisibleZoomRange(MapRange range)
```
    Set the visible zoom range for this layer. Current zoom level must be within this range for the layer to be visible.
    This range is half-open, thus layer is visible if range.min <= ZOOMLEVEL < range.max.
    
    参数:
    
    range - new visible zoom range
  - inVisibleZoomRange
```
public boolean inVisibleZoomRange(float zoomLevel)
```
  - isUpdateInProgress
```
public boolean isUpdateInProgress()
```
    Tests whether this layer is being currently updated.
    
    返回:
    
    True when the layer is being updated or false when the layer is in steady state.
  - update
```
public void update(CullState cullState)
```
    Updates the layer using new visibility information. This method is periodically called when the map view moves.
    The visibilty info is saved, so the data can be refreshed later.
    
    参数:
    
    cullState - The new visibilty information.
  - refresh
```
public void refresh()
```
    Refreshes the layer using old stored visibility information. This method might be called if some of the layer data
    changes.
  - deleteInGLThread
```
public void deleteInGLThread()
```
  - screenClip
```
public void screenClip(ScreenClipDirection direction,
                       float ratio)
```
  - getUUID
```
public int getUUID()
```
  - setLayerOpacity
```
public void setLayerOpacity(float opacity)
```
  - getLayerOpacity
```
public float getLayerOpacity()
```
  - setLayerBrightness
```
public void setLayerBrightness(float brightness)
```
  - getLayerBrightness
```
public float getLayerBrightness()
```
  - setLayerContrast
```
public void setLayerContrast(float contrast)
```
  - getLayerContrast
```
public float getLayerContrast()
```
  - setLayerSaturation
```
public void setLayerSaturation(float saturation)
```
  - getLayerSaturation
```
public float getLayerSaturation()
```
  - swigGetClassName
```
public java.lang.String swigGetClassName()
```
    Returns the actual class name of this object. This is used internally by the SDK.
    
    返回:
    
    The class name of this object.
  - swigGetDirectorObject
```
public java.lang.Object swigGetDirectorObject()
```
    Returns the connected director object. This is used internally by the SDK.
    
    返回:
    
    The connected director object or null if director is not connected.
