Methods​

load()​

load(normalizedDataSource, options?): Promise<GeoJSONShapesData>

Defined in: @tissuumaps-storage/src/geojson/GeoJSONShapesDataProvider.ts:79

Opens a data source and returns the loaded data accessor

The data source has to have been normalized by DataProvider.normalize beforehand.

Parameters​

normalizedDataSource​

NormalizedGeoJSONShapesDataSource

The normalized data source to open

options?​

DataProviderLoadOptions

See AnnotatedDataProviderLoadOptions

Returns​

Promise<GeoJSONShapesData>

A promise that resolves to the loaded data accessor

Implementation of​

ShapesDataProvider.load

normalize()​

normalize(dataSource, projectUrl): NormalizedGeoJSONShapesDataSource

Defined in: @tissuumaps-storage/src/geojson/GeoJSONShapesDataProvider.ts:68

Returns the data source with all of this data provider's defaults applied and all of its relative URLs resolved

Data sources that normalize to the same value are considered equal, and their data is loaded only once and shared between all referencing objects. Normalization has to be idempotent: normalizing an already normalized data source must return the same value again.

Relative URLs are resolved against the URL the project was loaded from, and against the document base URL for projects without one.

Parameters​

dataSource​

GeoJSONShapesDataSource

The data source to normalize

projectUrl​

string | null

The absolute URL of the project, or null for projects that were not loaded from a URL

Returns​

NormalizedGeoJSONShapesDataSource

The normalized data source

Implementation of​

ShapesDataProvider.normalize
