AGSLabelAngle Class Reference

Description

Specifies how to calculate the angular position and layout direction for labels on or around point feature symbols. The angular position may be different for each feature (driven by one or more feature attributes) or constant for all features (specified by a fixed number).

arcadeExpression

Creates an AGSLabelAngle object with the specified AGSArcadeExpression object . The AGSLabelAngle::rotationType property will be defaulted to AGSLabelAngleRotationTypeAutomatic.

Parameters

arcadeExpression

The arcade expression script.

initWithArcadeExpression:rotationType:

- (instancetype) initWithArcadeExpression:		(AGSArcadeExpression *)	arcadeExpression
rotationType:		(AGSLabelAngleRotationType)	rotationType

Creates an AGSLabelAngle object with the specified AGSArcadeExpression and AGSLabelAngleRotationType.

Parameters

arcadeExpression	The arcade expression script.
rotationType	Whether the angle should be interpreted as arithmetic or geographic.

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.

Reimplemented in AGSPortalItem.

Property Documentation

angleExpression

- (AGSArcadeExpression*) angleExpression

readwritenonatomicstrong

Specifies how the angle (in degrees) is calculated from the feature attributes, using an arcade expression. The calculation may use attributes, fixed numbers, or a combination of both. The default value is an AGSArcadeExpression property containing an empty expression string, which will produce a zero angle when evaluated.

Since

100.11

rotationType

- (AGSLabelAngleRotationType) rotationType

readwritenonatomicassign

Whether the angle should be interpreted as arithmetic or geographic. The default value is AGSLabelAngleRotationTypeAutomatic (which will be interpreted as AGSLabelAngleRotationTypeArithmetic).

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.
