Methods

public getCacheEnabled(): boolean

Returns whether or not caching is enabled for vector-based requestors.

Returns

boolean

Whether or not caching is enabled.

public getDataFormat(): string

public getUsesEndpoint(): boolean

Determines whether or not this requestor uses an endpoint rather than local data.

Returns

boolean

Whether or not this requestor gets data from an endpoint.
