Methods

defaultRetryParameters() → {shaka.extern.RetryParameters}

Gets a copy of the default retry parameters.
Source:
Returns:
NOTE: The implementation moved to shaka.net.Backoff to avoid a circular dependency between the two classes.
Type
shaka.extern.RetryParameters

getLocationProtocol_() → {string}

This is here only for testability. We can't mock location in our tests on all browsers, so instead we mock this.
Source:
Returns:
The value of location.protocol.
Type
string

makeRequest(urisnon-null, retryParams, streamDataCallbacknullable) → {shaka.extern.Request}

Makes a simple network request for the given URIs.
Parameters:
Name Type Attributes Default Description
uris Array.<string>
retryParams shaka.extern.RetryParameters
streamDataCallback ?function(BufferSource):!Promise= <nullable>
 null
Source:
Returns:
Type
shaka.extern.Request

registerScheme(scheme, plugin, priorityopt, progressSupportopt)

Registers a scheme plugin. This plugin will handle all requests with the given scheme. If a plugin with the same scheme already exists, it is replaced, unless the existing plugin is of higher priority. If no priority is provided, this defaults to the highest priority of APPLICATION.
Parameters:
Name Type Attributes Default Description
scheme string
plugin shaka.extern.SchemePlugin
priority number <optional>
progressSupport boolean <optional>
 false
Source:

unregisterScheme(scheme)

Removes a scheme plugin.
Parameters:
Name Type Description
scheme string
Source:

clearAllRequestFilters()

Clears all request filters.
Source:

clearAllResponseFilters()

Clears all response filters.
Source:

destroy() → {Promise}

Request that this object be destroyed, releasing all resources and shutting down all operations. Returns a Promise which is resolved when destruction is complete. This Promise should never be rejected.
Implements:

Returns:
Type
Promise
