Returns whether data object contains specific property

boolean

DataObject.hasProperty

▸ indexOfChild(data): number

Return index of child data ( index of the specified child or -1 if data is not found)

▸ isDisposed(): boolean

Returns whether this object has been disposed

▸ notify<E>(type, source, args?): CurveDataObject

Notify listeners

CurveDataObject

this

DataObject.notify

▸ off<E>(type?, callback?): CurveDataObject

Detach listener on event. Calling .off() with no arguments removes all attached listeners. Calling .off(type) with no callback removes all attached listeners for specific type.

CurveDataObject

this

DataObject.off

▸ on<E>(type, callback): CurveDataObject

Attach listener on event that will be called whenever the specified event is delivered to the target

If the callback function is already in the list of event listeners for this target, the function is not added a second time.

If a particular anonymous function is in the list of event listeners registered for a certain target, and then later in the code, an identical anonymous function is given in an "on" call, the second function will also be added to the list of event listeners for that target.

▸ onPropertyChanged(prop): CurveDataObject

This method is called if property bag is changed using setProperty method

▸ query(): QueryBuilder<any>

Query data item and child items by different conditions

Example

// Select by function
import {DataObject} from '@int/geotoolkit/data/DataObject';

const dataobject = new DataObject({'name': 'test', 'uri': 'testuri', 'type': 'testtype'});
const item1 = new DataObject({'name': 'item1', 'uri': 'item1', 'type': 'test'});
const item2 = new DataObject({'name': 'item2', 'uri': 'item2', 'type': 'test'});
dataobject.addChild([item1, item2]);
const item5 = new DataObject({'name': 'item5', 'uri': 'item5', 'type': 'test'});
item2.addChild(item5);
let founditem = null;
dataobject.query()
.where( (item: DataObject) => item.getParent() === dataobject)
.where( (item: DataObject) => item.getUri() === 'item2')
.select((item: DataObject) => {
founditem = item;
});

Example

// Select by expression
dataobject.query()
.where( 'item => uri(item) == "item5"')
.select((item: DataObject) => {
founditem = item;
});

QueryBuilder<any>

query object which has methods 'where' tp specify conditions, 'select' to run query, 'selectToArray' select results to array Expressions syntax: "item => expression", where expression:

• logical and arithmetic operators
• embedded functions: name(item) - gets name of the data object url(item) - gets url of the data object type(item) - gets type of the data object
