GLMapPointArray

Objective-C


@interface GLMapPointArray : NSObject

Swift

class GLMapPointArray : NSObject

Array of GLMapPoint. Usesefull to load lines and polygons into GLMapVectorObject. Based on C++ vector and works faster with GLMapPoints without obj-c overhead, *

  • Initialize array with no capacity hint

    Declaration

    Objective-C

    - (nonnull instancetype)init;

    Swift

    init()

  • Initialize array with initial capacity hint

    Declaration

    Objective-C

    - (nonnull instancetype)initWithCapacity:(NSUInteger)initialCapacity;

    Swift

    init(capacity initialCapacity: UInt)

  • Initialize array with points

    Declaration

    Objective-C

    - (nonnull instancetype)initWithPoints:(nonnull GLMapPoint *)points
