Detailed Description

A layer which contains any number of features. These features consist of attributes and usually (but not necessarily) vector geometry. This layer provides access to these features through various filters. Corresponds to OGRLayer. Its name property corresponds to the layer name.

Member Function Documentation

clear_cache()

void godot::GeoFeatureLayer::clear_cache

(

)

Clears all cached features. Note that this will cause newly returned features not to have shared signals and changes with previously returned features.

create_feature()

Ref< GeoFeature > godot::GeoFeatureLayer::create_feature

(

)

Adds the given feature to the layer. This change has no effect on the dataset on disk unless save_override or save_new is called.

get_center()

Vector3 godot::GeoFeatureLayer::get_center

(

)

Returns the point in the center of the layer in projected meters. The y-component is 0.0.

get_features_by_attribute_filter()

Array godot::GeoFeatureLayer::get_features_by_attribute_filter

(

String

filter

)

Returns all features which fulfill the given SQL-WHERE-like attribute filter, e.g. "attributename < 1000" Note that syntax errors are printed to the console by GDAL.

get_features_near_position()

Array godot::GeoFeatureLayer::get_features_near_position	(	double	pos_x,
		double	pos_y,
		double	radius,
		int	max_features
	)

Returns all features, regardless of the geometry, near the given position (within the given radius).

get_file_info()

Dictionary godot::GeoFeatureLayer::get_file_info

(

)

Returns information about this file: path: the path to the dataset name: the name of the layer within the dataset

remove_feature()

void godot::GeoFeatureLayer::remove_feature

(

Ref< GeoFeature >

feature

)

Removes the given feature from the layer. This change has no effect on the dataset on disk unless save_override or save_new is called.

save_new()

void godot::GeoFeatureLayer::save_new

(

String

file_path

)

Applies all changes made to the layer to a copy of the original layer which is created at the given path. Will be created as a Shapefile.

save_override()

void godot::GeoFeatureLayer::save_override

(

)

Applies all changes made to the layer to this layer, overriding the previous data permanently.

set_native_layer()

void godot::GeoFeatureLayer::set_native_layer

(

std::shared_ptr< NativeLayer >

new_layer

)

Set the OGRLayer object directly. Not exposed to Godot since Godot doesn't know about GDALDatasets - this is only for internal use.

set_origin_dataset()

void godot::GeoFeatureLayer::set_origin_dataset

(

Ref< GeoDataset >

dataset

)

Sets the dataset which this layer was opened from. Not exposed to Godot since it should never construct GeoFeatureLayers by hand.
