NTVectorElement


@interface NTVectorElement : NSObject {
  void *swigCPtr;
  BOOL swigCMemOwn;
}

A base class for all vector elements (points, lines, texts, models, etc).

  • Checks if this object is equal to the specified object.

    Declaration

    Objective-C

    - (BOOL)isEqual:(id)object;

    Parameters

    object

    The reference object.

    Return Value

    True when objects are equal, false otherwise.

  • Returns the hash value of this object.

    Declaration

    Objective-C

    - (NSUInteger)hash;

    Return Value

    The hash value of this object.

  • Returns the bounds of this vector element.

    Declaration

    Objective-C

    - (NTMapBounds *)getBounds;

    Return Value

    The bounds of this vector element.

  • Returns the geometry object that defines the location of this vector element.

    Declaration

    Objective-C

    - (NTGeometry *)getGeometry;

    Return Value

    The geometry object of this vector element.

  • Returns the internal id of this vector element.

    Declaration

    Objective-C

    - (long long)getId;

    Return Value

    The internal id of this vector element.

  • Sets the internal id for this vector element. The id is used for internal caching, and should not be changed by the user. User id can added to meta data as a key-value pair.

    Declaration

    Objective-C

    - (void)setId:(long long)arg1;

    Parameters

    id

    The new internal id for this vector element.

  • Returns a copy of the vector element meta data map. The changes you make to this map are NOT reflected in the actual meta data of the element.

    Declaration

    Objective-C

    - (NTStringVariantMap *)getMetaData;

    Return Value

    A copy of the vector element meta data map.

  • Sets a new meta data map for the vector element. Old meta data values will be lost.

    Declaration

    Objective-C

    - (void)setMetaData:(NTStringVariantMap *)metaData;

    Parameters

    metaData

    The new meta data map for this vector element.

  • Returns true if the specified key exists in the vector element meta data map.

    Declaration

    Objective-C

    - (BOOL)containsMetaDataKey:(NSString *)key;

    Parameters

    key

    The key to check.

    Return Value

    True if the vector element meta data element exists.

  • Returns a meta data element corresponding to the key. If no value is found null variant is returned.

    Declaration

    Objective-C

    - (NTVariant *)getMetaDataElement:(NSString *)key;

    Parameters

    key

    The key to use.

    Return Value

    The value corresponding to the key from the meta data map. If the key does not exists, empty variant is returned.

  • Adds a new key-value pair to the meta data map. If the key already exists in the map, it’s value will be replaced by the new value.

    Declaration

    Objective-C

    - (void)setMetaDataElement:(NSString *)key element:(NTVariant *)element;

    Parameters

    key

    The new key.
    element

    The new value.

  • Returns the state of the visibility flag of this vector element.

    Declaration

    Objective-C

    - (BOOL)isVisible;

    Return Value

    True if this vector element is visible.

  • Sets the state of the visibility flag for this vector element. If set to false the element will not be drawn.

    Declaration

    Objective-C

    - (void)setVisible:(BOOL)visible;

    Parameters

    visible

    The new state of the visibility flag for the vector element.

  • Notifies this vector element’s datasource about the change in this element. The data source may then notify the layer to update the view.

    Declaration

    Objective-C

    - (void)notifyElementChanged;

  • Undocumented

    Declaration

    Objective-C

    -(void)dealloc;
