Inherits from NSObject
Conforms to NSCoding
Declared in EILLocationLinearObject.h

Overview

Represents an object in a location which position can be described by a line segment. Typical examples are doors, windows, internal partition walls etc. Object is immutable.

Properties

  type

Type of the object.

@property (nonatomic, assign, readonly) EILLocationLinearObjectType type

Declared In

EILLocationLinearObject.h

  position

Coordinates of the object in form of an oriented line segment. Orientation typically represent direction toward center of the location, perpendicular to the line segment.

@property (nonatomic, strong, readonly) EILOrientedLineSegment *position

Return Value

A linear object initialized with position and type.

Declared In

EILLocationLinearObject.h

+ linearObjectWithLinearObject:

Returns a new linear object based on the given linear object.

+ (instancetype)linearObjectWithLinearObject:(EILLocationLinearObject *)linearObject

Parameters

point

A linear object.

Return Value

Parameters

dX

Value of translation on X axis.
dY

Value of translation on Y axis.

Return Value

A new linear object translated by (dX, dY).
