AGSRenderer Class Reference

Description

An abstract base class for renderers.

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

JSONObject	NSDictionary or NSArray containing the JSON.
error	encountered during the operation, if any.

isEqualToRenderer:

- (BOOL) isEqualToRenderer:

(AGSRenderer *)

other

Compares two renderers for equality.

Parameters

other

renderer to compare this one to.

Returns

YES if other is equal to self, otherwise NO.

symbolForFeature:

- (AGSSymbol*) symbolForFeature:

(AGSFeature *)

feature

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

Parameters

feature

The feature to determine the symbol for.

Returns

A new symbol for the feature.

Since

100

symbolForFeature:applyAttributeOverrides:

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

Creates 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

feature	The feature to determine the symbol for.
applyAttributeOverrides	If set YES, applies the override attributes from the renderer.

Returns

A symbol for the feature.

105

symbolForGraphic:

- (AGSSymbol*) symbolForGraphic:

(AGSGraphic *)

graphic

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

Parameters

graphic

The graphic to determine the symbol for.

Returns

A symbol for the graphic.

Since

100

symbolForGraphic:applyAttributeOverrides:

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

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

Parameters

graphic	The graphic to determine the symbol for.
applyAttributeOverrides	If set YES, applies the override attributes from the renderer.

Returns

A symbol for the graphic.

toJSON:

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

requiredinherited

Returns JSON representation for this object.

Parameters

error

encountered during the operation, if any.

Returns

NSDictionary or NSArray containing the JSON.

Since

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

- (AGSRotationType) rotationType

readwritenonatomicassign

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