Implements​

Constructors​

Constructor​

new GeoJSONShapesData(geometry, ids, names): GeoJSONShapesData

Defined in: @tissuumaps-storage/src/geojson/GeoJSONShapesData.ts:8

Parameters​

geometry​

ShapesGeometry

ids​

number[] | undefined

names​

string[] | undefined

Returns​

GeoJSONShapesData

Methods​

close()​

close(): void

Defined in: @tissuumaps-storage/src/geojson/GeoJSONShapesData.ts:38

Releases all resources held by this data object

Returns​

void

Implementation of​

ShapesData.close

getIds()​

getIds(): number[]

Defined in: @tissuumaps-storage/src/geojson/GeoJSONShapesData.ts:18

Returns an array of item IDs

The returned array is owned by this data object: callers must not modify it, and every call returns the very same array (see ItemsData).

Returns​

number[]

The item IDs

Implementation of​

ShapesData.getIds

getNames()​

getNames(): string[] | undefined

Defined in: @tissuumaps-storage/src/geojson/GeoJSONShapesData.ts:30

Returns the item names if available, otherwise undefined

Optional: data types that never carry item names need not implement it.

The returned array is owned by this data object: callers must not modify it, and every call returns the very same array (see ItemsData).

Returns​

string[] | undefined

The item names, or undefined if not available

Implementation of​

ShapesData.getNames

getSize()​

getSize(): number

Defined in: @tissuumaps-storage/src/geojson/GeoJSONShapesData.ts:26

Returns the total number of items

Returns​

number

The item count

Implementation of​

ShapesData.getSize

loadGeometry()​

loadGeometry(): Promise<ShapesGeometry>

Defined in: @tissuumaps-storage/src/geojson/GeoJSONShapesData.ts:34

Loads the geometry for all shapes

Returns​

Promise<ShapesGeometry>

A promise that resolves to the loaded shapes geometry

Implementation of​

ShapesData.loadGeometry
