AGSRenderer Class Reference

Description

Instances of this class represent renderers. Renderers symbolize geo-elements (graphics in a graphics overlay or features in a feature layer) based on a scheme. This is easier than symbolizing each graphic or feature individually.

Method Documentation

§ fromJSON:error:()

+ (nullable id<AGSJSONSerializable>) fromJSON: (id)  JSONObject
error: (NSError **)  error 
staticrequiredinherited

Initializes and returns an object from its JSON representation.

Parameters
JSONObjectNSDictionary or NSArray containing the JSON.
errorencountered during the operation, if any.
Since
100

§ isEqualToRenderer:()

- (BOOL) isEqualToRenderer: (AGSRenderer *)  other

Compares two renderers for equality

Parameters
otherrenderer to compare this one to
Returns
equal or not

§ symbolForFeature:()

- (AGSSymbol*) symbolForFeature: (AGSFeature *)  feature

Return a symbol for the feature based on the scheme used by this renderer.

Parameters
featureThe feature to determine the symbol for.
Returns
Symbol for feature.
Since
100

§ symbolForFeature:applyAttributeOverrides:()

- (AGSSymbol*) symbolForFeature: (AGSFeature *)  feature
applyAttributeOverrides: (BOOL)  applyAttributeOverrides 

Return a symbol for the feature based on the scheme used by this renderer and optionally apply attribute overrides.

If applyAttributeOverrides is set to YES and renderer contains an override expression, this method will return a symbol modified by the expression. If the expression cannot be properly evaluated due to missing fields or external data, then the original symbol is returned.

Parameters
featureThe feature to determine the symbol for.
applyAttributeOverridesIf set true, applies the override attributes from the renderer.
Returns
Symbol for feature.
Since
105

§ symbolForGraphic:()

- (AGSSymbol*) symbolForGraphic: (AGSGraphic *)  graphic

Return a symbol for the graphic based on the scheme used by this renderer.

Parameters
graphicThe graphic to determine the symbol for.
Returns
Symbol for graphic.
Since
100

§ symbolForGraphic:applyAttributeOverrides:()

- (AGSSymbol*) symbolForGraphic: (AGSGraphic *)  graphic
applyAttributeOverrides: (BOOL)  applyAttributeOverrides 

Return a symbol for the graphic based on the scheme used by this renderer and optionally apply attribute overrides.

Parameters
graphicThe graphic to determine the symbol for.
applyAttributeOverridesIf set true, applies the override attributes from the renderer.
Returns
Symbol for graphic.
Since
100.5

§ toJSON:()

- (nullable id) toJSON: (NSError **)  error
requiredinherited

Returns JSON representation for this object.

Parameters
errorencountered during the operation, if any.
Returns
NSDictionary or NSArray containing the JSON.

Reimplemented in AGSPortalItem.

Property Documentation

§ rotationExpression

- (NSString*) rotationExpression
readwritenonatomiccopy

Constant value or an expression that specifies the angle of rotation based on a feature's attribute value. When an attribute name is specified in rotationExpression, it's enclosed in square brackets, for example, [Rotation].

Since
100

§ rotationType

- (AGSSymbolRotationType) rotationType
readwritenonatomicassign

Controls the origin and direction of rotation. If the rotationType is defined as AGSSymbolRotationTypeArithmetic, the symbol is rotated from East in a counter-clockwise direction where East is the 0° axis. If the rotationType is defined as AGSSymbolRotationTypeGeographic, the symbol is rotated from North in a clockwise direction where North is the 0° axis.

Since
100

§ sceneProperties

- (AGSRendererSceneProperties*) sceneProperties
readwritenonatomicstrong

Properties to apply only when rendering data in 3D scenes using AGSSceneView

Since
100

§ unknownJSON

- (NSDictionary<NSString*,id>*) unknownJSON
readrequirednonatomiccopyinherited

A dictionary of values that was in the source JSON but was unparsed by API.

Returns
NSDictionary containing the unknown JSON.
Since
100

§ unsupportedJSON

- (NSDictionary<NSString*,id>*) unsupportedJSON
readnonatomiccopyinherited

A dictionary of values that are supported by the REST API, but not exposed through the SDK API.

Returns
NSDictionary containing the unsupported JSON.
