Getting started
This is a small utility class that helps you stream an object and all its sub-components from the Speckle Server API. It is intended to be used in contexts where you want to "download" the whole object, or iteratively traverse its whole tree.
Here's a sample way on how to use it, pfilfered from the 3d viewer package:
async load( { serverUrl, token, streamId, objectId } ) {
const loader = new ObjectLoader( { serverUrl, token, streamId, objectId } )
let total = null
let count = 0
for await ( let obj of loader.getObjectIterator() ) {
if( !total ) total = obj.totalChildrenCount
console.log( obj, `Progress: ${count++}/${total}` )
}
}
If you do not want to process the objects one by one as they are streamed to you, you can use the getAndConstructObject() method. Here's an example:
let loader = new ObjectLoader( {
serverUrl: "https://latest.speckle.dev",
streamId: "3ed8357f29",
objectId: "0408ab9caaa2ebefb2dd7f1f671e7555",
options: {
fullyTraverseArrays: false, // Default: false. By default, if an array starts with a primitive type, it will not be traversed. Set it to true if you want to capture scenarios in which lists can have intersped objects and primitives, e.g. [ 1, 2, "a", { important object } ]
excludeProps: [ 'displayValue', 'displayMesh', '__closure' ] // Default: []. Any prop names that you pass in here will be ignored from object construction traversal.
}
} )
let obj = await loader.getAndConstructObject( ( e ) => console.log( 'Progress', e ) )
