A layer that can display an integrated mesh.
An instance of this class represents a layer that can visualize an integrated mesh layer. An integrated mesh can represent built and natural 3D features, such as building walls, trees, valleys, and cliffs, with realistic textures and includes elevation information.

Cancels loading if it is in progress, otherwise it does nothing. This should be called carefully because other objects could be waiting for loadWithCompletion:
or retryLoadWithCompletion:
to complete and this will call them all back with the error of NSUserCancelledError
- (void) doCancelLoading |
Never call this method directly. The framework calls this method on a background thread when cancelLoad (AGSLoadable-p)
is called. It is meant to be overriden by subclasses. Subclasses should override this method to cancel loading their data and call loadDidFinishWithError: (AGSLoadableBase(ForSubclassEyesOnly))
at the end passing in an error representing NSUserCancelledError
.
Provided by category AGSLoadableBase(ForSubclassEyesOnly).
- (void) doStartLoading: | (BOOL) | retrying |
Never call this method directly. The framework calls this method on a background thread when loadWithCompletion: (AGSLoadable-p)
or retryLoadWithCompletion: (AGSLoadable-p)
is called. It is meant to be overriden by subclasses. Subclasses should override this method to load their data and call loadDidFinishWithError: (AGSLoadableBase(ForSubclassEyesOnly))
upon completion, passing in the error if any.
retrying | flag that is true if this method was called from retryLoadWithCompletion: (AGSLoadable-p) . |
Provided by category AGSLoadableBase(ForSubclassEyesOnly).
- (id<AGSCancelable>) fetchLegendInfosWithCompletion: | (void(^)(NSArray< AGSLegendInfo * > *__nullable legendInfos, NSError *__nullable error)) | completion |
Fetches the array of legend infos (AGSLegendInfo
) for this layer.
- (instancetype) initWithItem: | (AGSItem *) | item |
Initialize the layer with the provided information.
item | representing an Integrated Mesh Layer. The item's type must be AGSPortalItemTypeSceneService . |
- (instancetype) initWithName: | (NSString *) | name |
Initialize this layer with the name of a scene layer package within the application bundle or shared documents directory.
name | of the scene layer package (without the .slpk file extension) within the application bundle or shared documents directory. |
- (instancetype) initWithURL: | (NSURL *) | url |
Initialize the layer with the given URL.
url | The URL of an individual layer. |
+ (instancetype) integratedMeshLayer |
Create a new layer.
+ (instancetype) integratedMeshLayerWithItem: | (AGSItem *) | item |
Create a new layer with the provided information.
item | representing an Integrated Mesh Layer. The item's type must be AGSPortalItemTypeLayer . |
+ (instancetype) integratedMeshLayerWithName: | (NSString *) | name |
Initialize this layer with the name of a scene layer package within the application bundle or shared documents directory.
name | of the scene layer package (without the .slpk file extension) within the application bundle or shared documents directory. |
+ (instancetype) integratedMeshLayerWithURL: | (NSURL *) | URL |
Create a new layer with the given URL.
URL | The URL of an Integrated Mesh Layer. |
- (BOOL) isEqualToLayer: | (AGSLayer *) | other |
- (BOOL) isVisibleAtScale: | (double) | scale |
Check whether this layer is visible at a given scale.
- (void) loadDidFinishWithError: | (nullable NSError *) | error |
Only subclasses should call this method in doStartLoading: (AGSLoadableBase(ForSubclassEyesOnly))
and doCancelLoading (AGSLoadableBase(ForSubclassEyesOnly))
when done loading or failed to load.

requiredinherited |
Loads data for the object asynchronously. The completion block is invoked upon completion.
You can call this method any number of times, however only one attempt is made to load the data. If it is already loading, it will just continue to load (i.e. not force a reload). If it has already loaded successfully, the completion block will be invoked right away. If it has already failed to load, the completion block will be invoked right away with error previously encountered. This method supports multiple callers and will call them all back on completion. However, each caller's completion block will be invoked once and only once.
completion | block that is invoked when object loads successfully or fails to load. An error is passed to the block if the object fails to load. |
- cancelLoad
to cancel loading - retryLoadWithCompletion:
to force reload - (void) onLoadStatusChanged |
Never call this method directly. The framework calls this method on a background thread when AGSLoadable::loadStatus
changes is called. Subclasses can optionally implement this to know when their loading status has changed.
Provided by category AGSLoadableBase(ForSubclassEyesOnly).

requiredinherited |
Tries to reload when an object has failed to load. This method should be called judiciously. It should be called when:
cancelLoad
and then this methodIf the data hasn't started loading, it will start loading. If it is already loading, it will just continue to load. If it has already loaded successfully, calls back right away. If it has already failed to load, tries again. This method supports multiple callers and will call them all back on completion. However, each caller's completion block will be invoked once and only once.
completion | block that is invoked when object loads successfully or fails to load. An error is passed to the block if the object fails to load. |
|
readwritenonatomicassign |
The layer's altitude offset.
|
readnonatomiccopyinherited |
Attribution information of the layer.
|
readrequirednonatomicassigninherited |
Denotes whether the layer can change visibility or not.
|
readwritenonatomicstronginherited |
Security credentials to access the remote resource. Only applicable if the resource is secured.
|
readnonatomicstronginherited |
Full extent of the layer.
|
readnonatomicassigninherited |
Specifies whether the layer supports identify.
|
readnonatomicstronginherited |
The item the layer has been created from.
|
readwritenonatomiccopyinherited |
The layer's description.
|
readwritenonatomiccopyinherited |
The layer's ID specified in the web map item of ArcGIS Online or an on-premises portal.
|
readnonatomicstronginherited |
The error that was encountered during the most recent load operation. Will be nil if the operation succeeded.
|
readrequirednonatomicassigninherited |
Status of the load operation.
|
readwritenonatomicassigninherited |
The maximum scale at which this layer is visible. If the map or scene is zoomed in beyond this scale, the layer will not be visible. A value of 0
means there is no maximum scale threshold and the layer will be visible at the smallest scale available for the map or scene.
|
readwritenonatomicassigninherited |
The minimum scale at which this layer is visible. If the map or scene is zoomed out. beyond this scale, the layer will not be visible. A value of 0
means there is no minimum scale threshold and the layer will be visible at the largest scale available for the map or scene.
|
readwritenonatomiccopyinherited |
The name of the layer.
|
readwritenonatomicassigninherited |
The opacity of this layer as a value between 0 (fully transparent) and 1 (fully opaque). Default value is 1.
|
readwritenonatomicstronginherited |
The AGSRequestConfiguration object which defines the behavior and policies to use when accessing the remote resource. The default will be nil. If it is nil the [AGSRequestConfiguration globalConfiguration] will be used.
|
readwritenonatomicassigninherited |
Indicates whether to show legend information.
|
readnonatomicstronginherited |
The spatial reference of the layer.
|
readnonatomiccopyinherited |
This layer's sub-layers.
|
readwritenonatomiccopyinherited |
Block that is invoked when the sub layer contents changes.
|
readrequirednonatomicstronginherited |
The URL of the remote resource.
|
readwritenonatomicassigninherited |
Denotes whether the layer is visible or not. The visibility changes can be monitored using Key-Value Observing (KVO).
