Constructors

constructor

new PythonSkeletonSource(chunkManager: ChunkManager, options: SkeletonSourceOptions): PythonSkeletonSource
Parameters
- chunkManager: ChunkManager
- options: SkeletonSourceOptions
Returns PythonSkeletonSource
Inherited from (WithPythonDataSource(WithParameters(SkeletonSource, SkeletonSourceParameters))).constructor
- Defined in src/neuroglancer/skeleton/frontend.ts:657

Properties

OPTIONS

OPTIONS: {
    parameters: SkeletonSourceParameters;
} & {
    dataSource: PythonDataSource;
    generation: number;
}

RPC_TYPE_ID

RPC_TYPE_ID: string

Should be set to a constant specifying the SharedObject type identifier on the prototype of final derived owner classes. It is not used on counterpart (non-owner) classes.

chunkManager

chunkManager: ChunkManager

chunks

chunks: Map<string, Chunk> & Map<string, SkeletonChunk> = ...

dataSource

dataSource: PythonDataSource

disposedStacks

disposedStacks: any

generation

generation: number

immediateChunkUpdates

immediateChunkUpdates: boolean = false

If set to true, chunk updates will be applied to this source immediately, rather than queueing them. Sources that dynamically update chunks and need to ensure a consistent order of processing relative to other messages between the frontend and worker should set this to true.

isOwner

isOwner: undefined | boolean

key

key: any

parameters

parameters: PythonSourceParameters & SkeletonSourceParameters

refCount

refCount: number = 1

referencedGeneration

referencedGeneration: number

rpc

rpc: null | RPC = null

rpcId

rpcId: null | number = null

unreferencedGeneration

unreferencedGeneration: number

wasDisposed

wasDisposed: undefined | boolean

`Static` encodeOptions

encodeOptions: ((options: Options) => any) & ((options: {
parameters: SkeletonSourceParameters;
}) => any) & ((_options: {}) => {
[key: string]: any;
}) & ((options: Options) => any)
