createUrl

createUrl(contentParts: (string | ArrayBuffer | ArrayBufferView)[], mediaType: string, forceDataUrl: boolean): IBlobUrlManagerResult

Converts the passed content to a Blob and creates an Object URL. If the runtime platform does not support blob URLs, a base64 URL will be returned.
The life-time of the URL is connected to this instance. Free memory by either:
- calling revokeUrl() to revoke a single blob URL created with this instance.
- calling revokeAllUrls() will revoke all blob URLs created with this instance.
Parameters
- contentParts: (string | ArrayBuffer | ArrayBufferView)[]
  
  The contents that should be wrapped in a Blob and served with an URL. If a string is passed, text content is assumed.
- mediaType: string
  
  The media type the content should be served with.
- forceDataUrl: boolean
  
  If set to true, always create a data URL, even if URL.createObjectURL() exists.
Returns IBlobUrlManagerResult
The URL to the contents.
